Dan, FYI… If you want to run 5V on the bus instead of 8V, you really don’t have to remove the regulators (yeah, that sound like an annoying job). Just solder a jumper wire from input to output, then be sure you mark the board VERY carefully so you don’t put it into an 8V backplane. In this configuration, the regulators draw a very nominal quiescent current that is significantly lower than anything else on the board. I run many boards like this in two S-100 computers. I use a MeanWell QP-200F switcher that has been adequate for both machines, one a 12-slot and the other an 8-slot. I no longer heat my basement with these computers, and sans that boat anchor power transformer and filter caps, I can actually LIFT them now without getting a hernia. Now if I could just get those IDE/CF boards built and working so the 8” floppy drives could go onto a shelf… (Please, no help needed at this time on the IDE/CF card – I just need to find the time to work on the.)

I bought a few of the S-100 backplanes that Josh & Todd made a few weeks ago. But I'm still looking for a chassis. Which kind of mini S-100 chassis would you have ?
