There is a download for both versions of 8.04 here if your interested. In fact this provides links to a lot of old versions. I think the oldest you would be able to compile on would depend on your oldest pc. I know 8.04 wouldn't run on my dad's newish pc(maybe fixed in a later version of 8.04)

Suggestion for new versions of Prime95:

When Prime95 unreserves an exponent, have it place the reason in the prime.log file.

I added 2 exponents (1 per worker) today (using a worktodo.add file and forced communications). Once they were assigned AID's (and all of the manual comm. was done), I stopped and exited Prime95. I moved them to the head of each queue in worktodo.txt. Then I restarted Prime95. It promptly dropped the last 2 exponents off the list. My settings are for 10 days minimum work, 200 expos max, 365 days to unreserve. I had about 6 - 8 per queue and less than 2 months of work. Running v26.2

I noticed that when I started up Prime95 while I was compressing a video in the background, it suddenly works fine:

. Maybe you should load the CPU with a multi-thread workload before trying to detect (whatever it is you're detecting) ?

26.6 Win-x64 (p64v266.zip - 3.6 MB - 04.03.11 2:55:00) leaked into the ftp...

"Hands off!" or "Try at your own risk..." ?

Introduces a new undoc.txt item: NumPhysicalCores=n. For use in case where prime95 is not detecting cores/hyperthreading correctly. Specifically, dual-CPU hyperthreaded machines with hyperthreading disabled in the BIOS.

The estimated time of completion for this P-1 assignment is only showing Stage1 completion, not stage2. And even then it seems very wrong (it's 99% complete now, should be done stage1 in a day or so, not a month like the estimate says. And stage2 won't be done for many months, so that can't be right either).

Test/Status never displays the B2 value (applies to both P-1 and ECM). The estimate you see is for the completion of stage 2.

The formula for total stage 2 time (in seconds) is:
stage2_time = timing * (0.06154 * (B2 - B1)) * 1.285;
where timing is the time it takes to do one squaring. You can get this timing by doing Advanced/Time. Prime95 gets the timing by using a precomputed guess for that FFT length * RollingAverage.

I found that running Prime95 version 26.5 in my Windows 7 x64 PC with 12G RAM will cause my mouse clicking a little bit sluggish. Sometimes I need to perform a single click on a certain item for 2-3 times. When I stopped the Prime95 version 26.5 application, my mouse click operation will be very smooth and and click on a certain item ONCE.

I assume you left prime95 running at priority 1. How many workers are you running. How many CPU cores? Is your machine hyperthreaded? Are you in the middle of P-1 stage 2 which uses lots of memory? If so, how much memory are you letting prime95 use?

Prime95(user)-when Prime95 (program) v 26.5 is stopped on my pentium d, it restarts TF at 0% when continued. Not sure if happens on all pent d's, but has happened 3 times so far. If possible, suggest remedy or try to fix in next version. Thanks!

Is the disk full or write-protected?
