Didn't Astro of a while ago have a most excellent thread on his adventures with an old P90 CPU...!

Actually, it was a P60, the first generation Pentium ever released.

I just binned mine on the weekend...mind you it never ever did a seti wu, now or in the classic days.

Was it still in working condition? I collect computer parts as part of my hobby (I'm making my own sort of 'museum'), and I need an 'original' Pentium 60 or 66 (the only two speeds initially released) for my collection. I offered to buy Tony's, but he never got back to me.

I still have my socket 7 AMD K6-2 550mhz and lives on a GA-5AX v5.2 board nicely wrapped in it`s antistatic bag,
it ran seti classic wu in approx 18 hours over clocked to 600mhz stable as a rock almost silent, always cool.

one of its co crunchers is still on the go and works for cosmology@home http://cosmologyathome.org/show_host_detail.php?hostid=8152
It was in classic days a 600mhz amd slot athlon AMD-K7600MTR51B and took 12 hours,
I just dug it`s old cpu out of the cabinet beside me to check the number,
though it now has an upgrade from ebay (that works....)
a whole 1000mhz in the slot, so its a super computer by P60 standards.

Yada, yada, yada.

So there are those out there who run BOINC on the latest greatest and get to crunch a workunit a second and have a RAC in the billions. Yes? So?

2 of the machines I run SETI@home on are dual 450MHz Power Mac G4. OK, so they have 1.25 GB RAM each, but that's not going to help them crunch, much.

Here they are:
Apollo and Artemis

What's the SLOWEST machine you're running BOINC on? Something that's crunching daily, not a part time thing or something that you used to crunch one workunit on 9 years ago. Something current. A link to it is going to be required, I'm afraid.

Go on, show off, you know you want too :)

My old computer is not listed on the site any more. It was a Pavilion x86 family 6 model 8 stepping 1 Intel 605 Mhz. I used it to process 2,175 classic units at more than 24,000 hours starting in May 1999. I tried a few units when the switch to BOINC happend. Of the three I remember doing, I lost one due to an error. I got a credit of around 40 for another, and one unit timed out before finishing. At that point, I gave it up until I could get a bit faster processor.

16MHz? I could do one and only one better, 1.79MHz and that was an Atari 1200XL computer which I have now, But It's awaiting a new motherboard and psu brick which should cost Me w/shipping $60.68 total, Would It run Seti? Not likely at this stage as I'd need a C compiler and I'd have to configure Seti to do what Seti Classic did and yet support Boinc and in a limited memory envelope of 64K to 512K or even as much as 1024K, As hdd capacity or access to a hdd isn't a problem, Internet would have to be via dialup as the 1200XL has no ethernet capability. Somebody must have something slower, somewhere.

I just thought I'd let you know I used to have the Atari 800 and before that it was a Timex Sinclair with a Cassette drive. Unfortunately, the Atari was destroyed in a flood. But I do have my original pentium around here I can't remember if it was a 100 or 133. I might just have to take it apart and see, I have 2 others that aren't much faster, then a big jump to one on my list. A Dell Optiplex running 996 MHz. The pentium 100 or 133 was used on all of my SETI classic I couldn't tell you how long it took to crunch a workunit. Seems about like this optiplex, the fast ones 17 or 18 hours, some much longer. Aparently if you google atari computers down at the bottom there are still enthusiasts there will be a Swap meet in Columbus OH on Sept 13, 2008 so if you still need parts...

Don't worry I know where to get the parts, NOS parts too, Straight from the warehouse Atari used to own. Used parts may or may not work and I'd rather not always take that sort of chance.

Well I thought it was kind of interesting anywayz... Who knew???

The OP asked about machines that are regularly running.

I don't beat Joe, but My P233 MMX has just returned it's latest WU.

Sir Arthur C Clarke 1917-2008

Well I went to BOINC Stats and started looking around...Interesting enough when sorted by Average Credit per CPU second the pentiums don't start showing up until # 20 Intelx86 Family 5 Model 2 Stepping 5 90MHz there are 3 listed... above that at 18 unknown 486 with 2 listed...

the link for you to see for yourselves


<edit> BTW, before I sorted them I was looking manually through the list and found a lot of Computers that make Richard's seem really fast... Of course I used a Pentium 100 or 133, I think way back then I should pull it out and see if it will still run. there were over 2000 users for listings of around 297 - 300 Mhz.
