I Know it's stupid, I know it's pointless, and I know it will take months to do a single work unti, but I still wanna somehow get seti@home running on a 68K, any ideas?
Hey, it's better than having a land fill full of 030's?

Good luck. I have an 8600 at 200 Mhz and it takes about 25 hours to finish a WU. Those machines would take weeks. My father had an 8100 at 80 Mhz and it was 25% done after 20 hours. Any slower would be unbearable in my opinion. Don't forget the 24 Megs ram minimum. Most 68K machines won't have that.

You can't run SETI@Home on anything lower than a PowerPC 601 Processor.

People aren't as dumb as you think. Wait, what was I thinking, 90% of the world uses WINDOWS!
You don't like Macs? Good, more for me.

yeah but what about using a nix based os and a nix version, or what about an older version of VPC, and say win 95 and running the win version of seti?

I doubt LinuxPPC will work with 680x0 processors. Minimum requirements on VirtualPC 3 is a PPC 100MHz, and emulators are generally too slow to begin with.

an OLDER version of VPC, or softwindows would work.

I searched the SETI CLI download site and could not find a 68K client. There must have been one once because the CPU stats page lists 35,000+ Work Units returned from Motorola 68K. And that is not from the 68K netBSD client that has been retired, that only accounts for 189 WUs.

Yes, but that page also mentions a G5 processor, a "PowderPC", a "Drama Pentium", an "entium", a "gaga", and a "Pentium 4", along with dozens of other non-existent CPUs. Someone might be pulling your leg.
I seem to remember that ALL version of VirtualPC require PowerPC processors. There might be some DOS cards out there that might work, but I firmly believe that *ANY* emulator would be so slow as to be useless (30+ days per WU).
Are PPC upgrades still available for 68k Macs? I remember that Sonnet used to sell them, and that should bring you a PPC 601 at less than 100 MHz. If that is possible, that would mean 50-70 hour WUs, but it would be far better than 30-60 day WUs.

I'm not here to discuss how usefull or practical it would be, I'm here to discuss how to get it down. I'm pretty sure that at softwindows ran on 68K at one point, are there any processor limitations to seti running on windows?

SoftWindows 1 ran on a 68k, but it was Windows 3.1, which does not have a SETI client for it either.
Check page http://setiathome.ssl.berkeley.edu/unix.html . This is the list of all versions available for "off-OS" (non-Windows, non-Mac) computers. All of these SETI ports are CPU specific, and thus won't run on another without a serious rewrite, and none include Motorola 680x0, "m68k".
It is still possible, but you'll either need to find a 68k-to-PPC upgrade card or you'll need to port your own version of SETI from PPC to 68k.
Check page http://www.sonnettech.com/product/default.html for some of the available upgrades. Other manufacturers may still make these type of upgrade cards.

You say you only want to get it running and are not interested how useful and practical a seti@home running on a 68k is, but I want to mention anyway, that the seti@home server expects the WU results back before a certain period of time. As far as I can remember it's 1 week but I could be wrong on that. If it didn't get the result back for that period it passes the WU to someone else.

If SoftWindows 1 simulated a 386 or later then it should be possible. Run Linux or a BSD variety on it - there are about a half dozen CLI clients that may run under one or another of these configurations. If SoftWindows 1 only simulates a 286 or earlier, then there is just no way. Nothing I can think of anyway.
The SETI servers do reissue a WU if it does not return in a week. That is what they say anyway. However, they will give credit for an old WU so this would not matter unless you are the one who discovers the Klingon ultimatum. In that case you would have to share the blame for finding ET with someone else.
