and I want to say "add 'foo bar blat' after line blah"
Talked to the RE Attorney this morning, It be tough to prove w/o having a copy of the will which isn't public document. Would require a lawsuit to be started and for us to subeanu the will.
does halcmd spit out the offending line?
Jymmm, look at the bright side - you didn't buy a Bridgeport :)
you mean on an error?
it only spits out the line number
ok. maybe the offending line (or at least command) ould be a good thing
Our biggest problem is we have 21 birds, not easy to find a place for rental wise. We are looking at buying a MH.
you were referring to echoing the line itself?
crap - I gotta get to the grocery store, was gonna do that an hour ago
oh yeha - I have milk and donuts now
time for a snack
back in a bit
as soon as I think I might be able to get my EMC development machine up and running again, my wife's computer dies
no - haven't grabbed them yet
just ghost it
the problem is that the easiest solution for fixing her computer is giving her the hardware in mine
don't tell me you only have one computer's worth of parts around
are you in the boonies?
the advantage is taht I'd be able to upgrade that machine ;)
good god man
are you in the technology boonies?
I have only functional PC's around here (except hers)
yes - Vermont
I've heard of that place
do you have stores there? or UPS?
less than 1 mile from the factory that used to make 90% of the world's high density DRAM
(wehen 64kbit was high density ;) )
SWPadnos Should I buy/ship you out some P3 600 machines for $15/ea ?
I'll be placing an order to NewEgg as soon as my wife forgets that I spent $1400 on a ticket to Poland ;)
it may be a while
that's what she sait
The computers are ship, just think you'ld lose out in the shipping.
P3 600 machines are great for emc
she was trying to say something longer, but her throat constricted
cradek and no onboard video/audio either
SWPadnos that's the Poland thing?
no - that's cheap P3 computers
Poland is for a wedding
thought you were already married
in fact, I should call him - I have no hotel reservations yet, and I leave in two weeks
a friend for 20+ years is getting married there, so what the hell
visiting old friends is nice
would be better if my wife were coming along, but oh, well
SWPadnos Just an excuse to justify seeing Poland, huh =)
but I avoid weddings whenever possible...
cradek including your own?
or was there a shotgun involved?
Jymmm: um do you know something I don't?
it's funny - the first movie Sharon and I saw together was "Four Weddings And A Funeral"
we used to call it "Five Funerals"
cradek oh, I thought you were married for some reason
nope, not married, not single either
cradek: and jepler doesn't count
no - he writes software to do that
jepler's not really my type - too brainy
* Jymmm bets he could guess cradek's "type"
let's not play that game
cute, big tata's, can cook, keep a home. and overall fun spirited
how close did I get?
I'm sure it's the same as everyone else: good looking (subjective), fun to be with (subjective), interesting (subjective) ...
fwiw, swp is definitely closer
I never meant cover of a magazine.
covers of magazines aren't that fun to be with
what's that old saying... beauty is in the eye of the beholder
"beauty is in the eye of the beer-holder"
(it's funny that I remember those, because I really don't like beer
beer is ok sometimes but coffee is better
you're not a drinker at all (for the most part) iirc
Bailey's is about it
ever had a Bit O Honey?
coffee and bailey's is always better
coffee and Bailey's is my preferred form
milk is OK as well
Baileys and Butterscotch Schnapps. Very good even if you're not a butterscotch fan.
too bad I just finished the donuts
what's your secret? seems you're always eating donuts or ice cream
Bit O Honey == Baileys and Butterscotch Schnapps.
nice MB: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260019736595
4 pci express??
I don't think so - 2 x16, plus 1 x4 with an x8 slot
it's basically the motherboard I have, but it has an Ht slot as well
mine does have a parport
I've been a little tempted to get one of these and put two full consoles on it (running two X servers) for both of us to share
half the fan noise, HD noise, heat, etc
not necessarily this board, but one that handles two video cards
cradek two X servers?
interestingly, there's a nice quiet power supply from PC Power & Cooling that's very quiet, and can run this board
sure why not
cradek you mean like dual consoles 2 kybd, 2 crts, 2 mice, ?
could use two dual-head cards even (I'm used to two screens now)
that board needs a larger than normal case though
it's full EATX
it does look big
cradek sounds like you could use a vga terminal
or SVGA I suppose
plugs into ethernet, and acts just like remote terminal.
oh X station? I have some of those, they're not fast.
they're from the old days
the newer ones allow you to upgrade the video cards
used to use one at work, no fan, no HD, totally quiet
the real killer is 8-bit color on mine
that used to be normal, now I doubt apps would even work right
[00:27:21] <Jymmm> http://www.imsltd.com/products/terminals.htm#book3
that was NOT the one I was looking for...
I use old laptops as X stations at home, bought a bunch the same, they boot from a floppy and load everything over the network
[00:29:01] <Jymmm> http://www.wyse.com/products/winterm/5150SE/index.asp
sorta like that one
probably no good as a primary machine, but might have its place
also found these (used wyse terminals "thin clients") http://www.interstateterminals.com/Terminals.html
3270 emulation built in :-)
you know, if you can get pizza box cases, CF card to boot to the net wouldn't be a bad thing
you can do it with a floppy but it's very tight
CF I'd think be faster.
who cares how fast it is
instant on might be a nice touch
true but if the screens shut off, no harm in leaving them on
Yeah. I like the used laptop idea better. Seems suited for the task.
it's dirt cheap to buy laptops with no hard drive, no cdrom, no battery
Then you REALLY can toss in a CF card in place of the hdd and netboot
8MB CF cards are cheap
or a floppy :-)
yeah I bet the tiny cards are dirt cheap now
I bet ppl are giving them away if you ask.
I know I have an 8MB, 64MB and 110MB CF cards I don't use
Hell, I have 30 pin simms for that matter
I have 10, 64, 128, I only use the 64
SWPadnos yeah, weird number, price was right though.
I haven't seen any non-power-of-2 capacity before
I only use my 1GB cards
or my 512MB if It's tight.
maybe it's 128, dont know. All this "GET OUT" doens't have us thinking too straight the last couple of days.
and to think that all I have is two 16M and one 512M card
both xD though
They're for my Nikon D70
I get a weird smiley for ex-dee cards ;)
they have >200 computers that have PIII-600 or higher, 512M or more, and are $200 or less
and 40-60 that are $100 or less
machines like that are everywhere
I guess that'ws why they have them
well usually it seems like you have to add ram
but pc133 ram is everywhere too
these have 512M, so that should be OK
and the CD-ROM is included
CD-ROM drive, and ~20G hard drive
did the link not work?
heh, I didn't try it
here's the cheap one: http://www.retrobox.com/rbwww/home/unit_view.asp?id=1698578&bin_id=world
yeah - a good terminal
Oh, I found a solution for my pedant problems... RF remote control
they have a few with DVD-ROM and 512M for $110-ish
I've still not needed a dvd so far
Jymmm, I'd be leery of that
a DVD-ROM is good if you want to watch DVDs ;)
true I'm sure
SWPadnos, Yeah, I know. it's 300MHz Hopefully there won't be many garage doors within a MH park.
there's now software that's distributed on DVD, but not that you'd run on that kind of machine
not that - machine noise could cause the PC to lose the "key release", depending on how the remote and the PC side software are set up
SWPadnos: Oh, I'd only use it for jogging and zeroing out the axis'es
key release on jog...
jog + missed key release = travel without stopping
I agree, any wireless seems like a really bad idea
push button, axis moves... let go, axis keeps moving
of course, the most likely panic response would be to hit the key again, and you _might_ not miss that key release message
I'm not sure that that kind of problem would happen, but I see it as a possibility
well, I should get boring
man - they've got P4-2.8 GHz machines with 512M and CD-RW/DVD-ROM for $276
you are boring ;)
heh their cheapest machine is 98c
you achieved your goal rapidly :)
jmkasunich: See, I wasn't the smartass this time, SWPadnos was. (Though I was thinking about it =)
.geez - that $0.98 machine could run a headless EMC
.98 + shipping
free for shipping
I'm sure the $1.82 one could :)
but if you find them locally they're just free
it was only a few years ago 300-400 MHz machines were our daily workers, they're still the same speed today
it's sad that an equivalent to my panel PC is $25.38 or so
software is slower though, so you've got to keep up
hell it was only a few years ago that 33-40 MHz machines were our daily workers
Computers are the only thing that are worht thousands today, and hundreds tomorrow.
cradek: thats more than a few now
same as cars, until they're old and unused
I think it was 15 years ago or so
67 Camero SS
SWPadnos: that software still works just as well too
well not all of it I guess
hey jmkasunich, where's that photo of the truck that was upended by the pallet jack?
when I started with Reliance Electric in 1991, I was assigned a 33MHz 386
one of the retired files directories, maybe 2002? 2003?
named truckfront.jpg or something like that
jmkasunich: you got your very own cpu? they must not have been using unix :-)
no they werent
I remember one of our professors getting a 486-33 - man that thing was fast!
there were a couple unix boxes, used only for Mentor PC board layout IIRC
when I started at this company about ten of us shared a 40 MHz 68040
sparc 2's or something like that
I think that's the one who has the second patent ever on a piece of software
it was old, but it still worked
[00:56:08] <Jymmm> http://www.interstateterminals.com/Terminals.html
before that I did cad on a sun 386i? i386?
[00:56:15] <Jymmm> http://www.metalworking.com/dropbox/_2003_retired_files/TruckBack.jpg
[00:56:24] <Jymmm> http://www.metalworking.com/dropbox/_2003_retired_files/TruckSide.jpg
dat beez da one
yep - found those
though the back photo wouldn't load correctly from the file listing
just recently I fired up that same 68040 to read some very old tapes!
still works fine of course
aha - they have a capital D in dropbox on the directory link
gotta yell at steve stallings about that
hmmm - nope. I got a bad version of the directory listing
now it works fine
that's so weird - TCP is supposed to be a reliable transport. I wonder how I get erroneous web pages
pages plural? it happens a lot?
I see it daily, I think
sometimes it's on generated pages, like eBay search results
SWPadnos: TCP is, but you have to remember about dropped packets.
you're supposed to get an error if a packet is dropped and no replacement arrives
it might take 15 dropped/resent packets to give the final results
it's weird that in this case, I had one bad bit - a 'd' changed to a 'D'
sure, so I'll have to wait longer, but if the browser is finished loading the page, then I should have all the information, and it should be correct, as far as a CRC32 can tell
SWPadnos assuming the http server isn't fubaring
sure - I'm not sure I've seen it on static pages, so it could be any number of problems at the server enc
I don't recall ever seeing that
maybe your machine is somehow bogus?

I stopped in because I have a hang-up I hope someone may be able to help with.
The company I work for is switching to linux for workstations and I will get a sweet new computer with Pro NC.
mecheng: describe the problem
However I can't seem to find any good posts or gcode editors or anything for linux.
post processors I mean
pro-e uses Gpost which doesn't work under linux
any info on where to start or look for info would help.
[15:36:44] <cradek> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?Cam
I will read through it today thank you very much.
I hope it helps (I don't know much about the stuff there)
this channel is about emc which is just a machine controller, most of us don't use cam
not that we wouldn't like to ...
I think you'll find that there aren't a lot of inexpensive options for CAM on Linux
well, I should rephrase that - there are free options for CAM on Linux, but they probably don't interface to your CAD software, and the user interface won't be what you'd like
for Linux CAM that is easy to use and interfaces to CAD, I think there are only expensive options
(but I'd love to be wrong about that)
yes that is what I have found as well.
We already have good CAM software for linux (Pro-Engineer) just need to convert APT-CL files to G-Code.
and maybe have a nice editor to read the gcode after it is converted.
there was some work done on a G-code syntax hilighter for Kate (the KDE editor)
yeah something like that.
it's straight text, but at least it would show different kinds of commands in differnt colors
That is exactly what I need
I can have IT Dept customize it as well
it didn't work well for me, but I may not have had the final version
any way to get a hold of it?
I'd love to see something that could collapse groups of similar codes - like a bunch of G1 moves (with a little +/- icon next to the group
hmmm - I'm not sure where it is, except on some BDI discs
no problem I will probably make something anyway
haha that would be very cool (the +/- thing)
the hilighting file format for Kate (and probably GEdit) is a relatively easy to understand XML file, with regular expressions for determining the tokens to hilight
bbiab gotta go work for a sec.
wow - this one looks great: http://www.cnc-syntax-editor.com/
yeah no,linux support though. There are plenty of good free ones for windows.
I like the "mirror" dialog box
yes mirror seems nice but I never seem to use it.
well time to go flip my part and hit cycle start again :)
more useful for people who write code by hand, I imagine
yeah hand writing code is a pain. Especially on a 5 axis machine :)
hard to get the math right all the time ;)
yeah and switch on +/- and KABOOOOOOOOM!!!
APTOS seems interesting but old.
SWPadnos, Thanks for the help yesterday.
there sure - did you get it going?
I went back to the transcript and digested it a bit. Now it make sense. Not that bad once you see a few simple relationships.
you can probably decrease the BASE_PERIOD by quite a bit as well
I haven't started making changes yet.
what's the CPU speed again?
But I wanted to ask...
The BASE_PERIOD I left at the default I think- 50 uS (50000 nan0Sec)
right - but you can get faster (or smoother) operation if you decrease BASE_PERIOD
Q is: is there a rule of thumb or formula for determining the theoretical min. BASE_PERIOD based on uP speed or sdomething?
yes, but it doesn't work ;)
Sorry I was typing while you asked-
I think the limit is in the 6-10 microsecond range (for most computers)
uP speed = 733 MHz
and it gets wirse as you move to slower computers (I think Alex had it down to 6 uS on an Athlon XP 1800 or so)
it really depends on the chipset as well
So I could go 5 - 8 times faster?
I have a Celeron 500 that can reliably do 20, and I'm pretty sure I've had it down to 16 or so
you can probaably get to 20 easily enough
this is a P3 @ 733 (I think thats right)
you can tell that you've gone too far if the machine locks up when you start EMC ;)
Just got it used awhile ago. Have to double check that.
OK, just like WQindows then. ;)
you'll notice a slowdown in X when you're getting close to the limit
I'd try 20, and con't bother going further if that works
why x only? First to process or what? Just curious.
the problems occur when the execution of the base thread takes up too much CPU time
if the thread period is shorter than the execution time, the machine locks up (it never finishes that thread, since it restarts before it's done)
if the thread takes up a lot of PU time, it just makes applications slow - it's basically loading the CPU a lot, in the kernel
so if you go down to 25 uS, and X is still reasonably snappy, you can probably go further
OK I'll try that. Might as well start with an optimal system before I do all the calcs for MAX_VEL etc.
I think the default used to be 20 or 25 uS, but it was changed to 50 when there was a bug in RTAPI that would take several microseconds per thread (for time measuring, ironically)
you should figure out what step rate you want, and choose the base period for that - no sense going much further than necessary, since it will impact the performance of other parts of emc (such as the UI)
OK. By the way, the "resonance I thought I had seems to be actually due to software kinematics settings. When I approach moving faster than the numbers allow, that's when I start seeing roughness.
OK, that makes good sense.
Main thing is getting the BASE_PERIOD up fairly near to the optimum (with your last note taken into consideration) so I can increase the uStepping rate to a good level.
That really helps a lot for quiet operation. BIG difference.
Even at 2K compared to 400.
Thanks again - I'll give it a try. I think I understand enough to get it right now. I really apprecite that. Immensely.
no problem. good luck
SWPadnos, or anyone - one more question please?
What determines the velocity sent as the starting velocity on an axis during an accelerated move?
Is it the DEFAULT_VELOCITY in the TRAJ section or what?
Or just same always?
davidf: I don't understand the question
err -that was what I was going to say :)
(& accel at MAX_ACCEL?)
hierr, hium, hi guys
sorry to jump in, I only read the last line or two
well, I guess the starting vel. is 0 of course.
But is the vel simply dependent on the acceleration?
is your question "what is the default acceleration used on a move, and how does it change?"
hi er hello err howyadoin cradek
Well I guess I didn't think about the Q enough first.
wonder how I typed control-Us in there
heh - I was wondering what the [\0x15] was for (I assumed it was a color thing - that whould be bright white)
acceleration is limited (for all moves) by the axis acceleration (from AXIS section) and the tooltip acceleration (from TRAJ section)
ctrl-U is "clear the line" in irssi
and many other terminal programs
not right then it wasn't
although it's working again
ok, so say you set the acceleration to 0. Then you cant make a move at any velocity, right?
My question is really - Is there an independent velocity figure for the axis or is the vel at any given moment, including the start, entirely dictated by the time and Accel?
I thikn the answer may be that the overall accel for the move will be governed in the same way as the velocity, except that there's no limit from the G-code
for a single-axis move, the TP will accelerate at the maximum of the following, with the limitation that it won't try to accelerate at a rate that would overshoot hte endpoint:
the following being the axis MAX_ACCEL and the TRAJ MAX_ACCEL
cradek can correct me if I'm way off - he wrote it ;)
davidf: each servo cycle, emc commands the machine to a new position. The new position is such that you can move from the old position to it while respecting the velocity and acceleration limits.
davidf: however, "stepgen" issues all the pulses during a particular servo cycle at the same rate (+- 1 base period), not an accelerating or decelerating rate during a single servo cycle
at the start of a long move (when coming up to cruise velocity) you are restricted by just acceleration limits
OK so in a G01 say, the move starts at v=0 and simply increases velocity over time according to max_accel respecting the vel limits.
I think that might have been the question, still not sure
yes that was the Q.
and when you get near the end, you have to start decelerating at the same max_accel in order to stop in the right place.
2B || !2B =Q. :)
could someone give me a hand with make emc2 pls?
yep - ask away
I get an error "Depending rtapi/rtai_ulapi.c"
in make process
don't know how to handle it
did you apt-get build-dep emc2 emc2-axis ?
(I'm assuming this is an ubuntu installation)
as a matter of fact no... I am still haing a go
with installing emc2 on my slack distro
please put the full error on http://pastebin.ca/
-- the message "Depending rtapi/rtai_ulapi.c" is not an error message, it is a normal step of compiling emc2.
well - I'm not familiar enough with the build process to help you there - jepler is the man
thanks all the same
on my system line 299 of rtai_config.h reads
on my system line 299 of rtai_config.h r 299#include "/usr/src/linux-headers-2.6.12-magma/include/linux/autoconf.h"
this may indicate that there is a problem with your rtai installation, or that it requires an extra -I argument that we are not using
that #include on line 299 must find the file that is associated with the correct kernel, and the one in /usr/include/linux/config.h is generic, as described at http://ep09.pld-linux.org/~mmazur/linux-libc-headers/doc/FAQ
mine on line 299 reads: #include <linux/config.h>
perhaps the search path is not correct
it is true that we don't use the flags printed by '--lxrt-cflags
er, 'rtai-config --lxrt-cflags'
root@darkstar:/home/pier# find /usr/src/RT_linux-184.108.40.206/ -name config.h
what does 'rtai-config --lxrt-cflags' print?

here's what it prints on my ubuntu system
well, you may wish to manually add -I/usr/src/RT_linux-220.127.116.11/include in Makefile's CFLAGS
in the INCLUDE variable?
make went further now!
[19:11:48] <pier_casa> http://pastebin.ca/144938
sounds like the wrong include

pier_casa: can you pastebin your Makefile.inc ?
ok right away
[19:16:36] <pier_casa> http://pastebin.ca/144946
I dunno -- my bitops.h doesn't seem to include <linux/config.h>
pier_casa: reading it now, just as a small matter, it might be wiser to try to run it in place first
maybe, but it won't fix the compile errors
then afterwards try to install it to the proper location .. I suspect it will save you some problems first
no, of course not.. but it helps dividing possible issues on the way
jepler: do you need to include /usr/realtime/include for CFLAGS?
alex_joni: there are probably lots of things there that are superstition...
jepler: I hear ya ;)
perhaps it is not correct... but wouldn't a ln -s to /usr/src/RT_linux-18.104.22.168/include/linux/config.h /usr/include/linux/config.h do?
pier_casa: when doing make prepare_all, that should be done automatically I think (or at least something similar involving symlinks..)
pier_casa: I'm talking about the kernel make..
but it's been quite a while, can't really recall
I did that long ago so I can't recall either
pier_casa: sorry, can't say I know what to tell you..
but it seems odd that you get that message, it sounds like it thinks you're compiling a kernel module
which you aren't (halui is only user-space : defined by -DULAPI)
maybe jepler knows how to make it more verbose
maybe there is a -DMODULE in the cmd line
spooky thing is that I managed to compile once
but giving the ./script/emc command
on the old program returns
EMC2 - 2.0.1
./scripts/emc: line 129: /usr/local/share/emc/tcl/bin/pickconfig.tcl: No such file or directory
oh, sounds like you didn't do 'make install'
so I decided (perhaps stupidly) to compile again
emc is compiled for installed, and you are trying to run it in place
without the scripts/ before it
should be in /usr/local/bin/emc (if you did 'make install' )
no.. there isn't such file
this will print the compiler commandline used: objects/hal/utils/halcmd.o
I just can't paste right today
jepler: we can understand, you've been away lots :D
make -n objects/hal/utils/halcmd.o
pier_casa: try 'make install'

make install returns always root@darkstar:/home/pier/emc2/src# make install

did you alter your rtai installation since you first compiled emc2?
no... I compiled a new kernel 22.214.171.124 but now I am running the rtai patched one
pier_casa: did you re-run ./configure ?
configure gives an encouraging message :)
that's the reason why it wants to compile again
what's in /usr/src/linux ?
the old (patched) or the new 126.96.36.199 kernel ?
I see KERNELDIR = /usr/src/linux in your Makefile.inc
/usr/src/linux points to
ok, that sounds legit
can you try what jepler suggested?
make -n objects/emc/usr_intf/halui.o
what does it print?
I'll try again

well, remove the "@" from the lines under "Rules to make .d (dependency)" files in Makefile
the leading @ on each of 4 lines
then it will print the commands
pier_casa: care to share what it says now?
I am afraid I made a mess

can you pastebin the whole Makefile ?
sorry for that
pastebin may not make the error visible, because in Makefiles a tab is different from 8 spaces...
oh, right.. what editor did you use?
might be one of those that converts tabs to spaces

pier_casa: that's still Makefile.inc, not Makefile
gotta run for half an hour.. jepler knows this better than me anyways .. bbl
well maybe but my real work is also crying for my attention
ok ok thanks
perhaps I might run in here again to get thi sorted out
pier_casa: back now
alex_joni, I have not been on when your were for some time, must be the time difference
How are your projects?
not sure what you mean ;)
but most are well ..
I think you were working on halui the last time
oh, yeah.. I like to think that's finished now
till someone proves me wrong ;)
I was told today that the machine I am working on now is going to Mexico
oh .. nice
Nice for me, A free vacation to Mexico, to install and train
sure sounds nice ;)
I have never been to Monteray
Two weeks will be nice, and the company pays the bill for both my wife and I
danex: same here, if that counts for anything :)
What is your local time now, I am in eastern US zone
Day changed to 23 Aug 2006
just now ;)
GMT+3 right now
00:01 < alex_joni> GMT+3 right now
your clock's fast
cradek: ntpdate might be sleeping
2 more minutes till tomorrow :)
cradek, did you see the note I left yesterday?
Had some storms yesterday, so the internet went up and down a lot
anyway I got the brake signal working for each axis
danex: working as it should?
It,s Wednesday for alex_joni now
danex: sure is
Yes, but needs to be tweeked
The question I have is about the min and max for wcomp. What are the values in
I.E. pulses, volts, etc.
depends on what you want to compare
it's just a window comparator
if they're the pos ddt, they're in units/sec
you feed in a signal, then you have a min and max (if the signal is position, then unit is mm or inches, if it's speed then it's units/sec, etc)
so based on what you intend to compare
The other problem I have is that the axis overshoots by 10 micron +/- and then hunts till it is exact
sounds like PID tuning not OK
that's just a tuning problem then
danex: first hunch is that P is too low, but I haven't done this that often
maybe a bit of FF1 can help too
Some CNC i have worked on in the past have a parameter for inposition ?
might play with FF1 too (it's very sensitive)
danex: emc2 has too (HAL pin motion.in-position iirc)
What effect doe FF1 have in relation to FF0?
FF0 is position feedforward, and FF1 is speed feedforward?
danex: I only read about it a few times.. so don't bet any on my word :D
HAL pin motion.in-position iirc? any documentation on this one?
danex: try "halcmd show pin motion"
it will tell you the HAL pins starting with "motion.."
iirc = if I remember correctly
I will have to look at that one in the morning, after the Fire Department lets us back in the building
A forktruck driver hit a Gas tank, now it has to be inspected before we are allowed back in
Might be 10:00 before I can get to the machine
What computers do you suggest for emc?
danex: 7-800 MHzish
maybe P3 or better
very modern processors aren't that good
I am running one I really like (Athlon XP 1400+, a couple years old)
In the past I have used AMD only
They seem to work good
alex_joni, sorry about the disconnect, had a power failure
I am going to shut down now
Thanks alex-joni and cradek for the help
* alex_joni heads to sleep too
