You can always rotate the cop, just remove the fan and physically rotate the clip 180 degress ^this. But going trough the trouble of removing the fan is not needed - simple small socket 7 heatsinks like the one in the pic do not cover the latch mechanism part of the cpu socket, and the clip can …

Rotate the CPU cooler so the clip winds up on the other side. Easy.
Re: Your favorite retro socket/platform
Posted on 2020-07-12, 15:31
Hmmm... hard question to answer. From a practical point of view, my favorite platform would be super socket 7 since it's the most flexible. Runner up would be socket A for it's performance in 1998-2002 3d games, as well as it's ability (*with an athlon XP Mobile) to run a slew of older dos games. …

Would it be possible that the PSU could be causing these issues? It's pretty old and beat up...

Odd about the cache chips not running same voltage. Maybe the tag you have is 5v, not 3.3v so it acts up if supplied at 3.3v. Also possible you have all 3.3v non-5v tolerant chips and they do not like 5v supplied to them, Do the main cache chips get warm ? What are the cache model numbers you have …
Re: Resurrecting an old IBM Valuepoint 486 machine. How can I get it to contribute to World Community Grid?
Posted on 2020-07-11, 16:19
I love these old IBM Valuepoint machines. I have a similar one but the motherboard is very restrictive. No L2 cache, and it only takes a special IBM cache card similar to a COAST module for socket 7 boards. The bios is also very limited, and it will only run with drives smaller then 1.2GB. It seems …

Hi. I got my hands on an IBM PC100 Type 6260 (dumpster find) and I'm trying to get it up and running, and upgrade it a bit to fit my needs. I have a bit of a soft spot for these old IBM machines, so although I have other (working) socket 7 hardware, I'd love to get this one up and running. The PC is …
Re: Is there any reason to keep a Win9X machine around for gaming except for fun or nostalgia?

no. Retro games and legacy software are the only reason to keep a win9x machine. Plenty of reason for me.

Interesting thread. I have a Lucky Star 5VP3 socket 7 board that will run at 8, 20 and 40 MHz unofficially. I discovered 8MHz accidentally when trying to get a K6-2 to run at 6x66MHz. It's stable at all these speeds, but at 8MHz multiplier selection is disabled, the board will always force 1x …

The manual says to use 1-2 closed, 3-4 open, 5-6 open on JP2 for non-intel CPUs - is that the setting you used? If that results in 4x, have you tried the intel 2x setting (1-2 closed, 3-4 open, 5-6 closed)?

I seem to remember someone saying that the motherboards that have the 4pin P4 plug are not entirely safe from this issue either and you still need a powerful 5V line. Has anybody ever looked into that? OP, are you running the original Thoroughbred 2800+ or a Barton model? Phil's Computer Lab tested …
