The adapter arrived today, and it appears to work just fine. I was planning to use a newer ATX PS, but it has a 24-pin connector (not a 20+4), so the adapter's connector would not fit. I scavenged a 100W ATX PS (without a -5v rail) from a dead OEM box, and it posted a 486 DX2-50 / VLB board. I need to find an old AT keyboard connector adapter now to do any more testing, however.

You can turn on the power with a jumper loop or with a power switch, both included. The power seems to be a little tocuhy, though; if you jostle either one, it will kill the power. Not sure if this has to do with the adapter or with the crappy PS.

That's odd, how does it not fit?

Can you clip parts off the connector to make it fit?

I guess you could break off the tab on one end of the connector, yes.

This is one of the reason why I use cheap OEM desktops: when a PSU blows up I do not lose too much $ in exotic hardware. 😀

Just have to deal with awful unflexable BIOSes

Well it could take some nice ISA cards with you...

BIOS isn't an issue. I would say that is a plus, especially for retro gaming beginners. OEM machines are very stable and just work. No need to fiddle around with settings 😀

Exactly. To be honest: I play games up to the Pentium 1 era. This means tweaking was very limited: games work or do not. 😀 Very different from the later overclocking era.

And I no longer use expensive ISA cards: just MIF-IPC-A replicas. In case one of those blows up: limited loss. Much better than losing a LAPC-I / SCC-1 and so on. 😀
