S-100 Power Supplies: thanks!

Hello all, Thanks to all those who replied to my message regarding S-100 power supplies, and thanks especially to Dick Erlacher, who offered to sell me some cheap. I got a private email reply from someone offering the same thing, and I took him up on it first. So to Dick, I'll pass but thanks anyway... The main problem in all of this was not ever the design. As Allison pointed out, an unregulated supply is dead simple to design. Even looking at some commercially designed/built S-100 supplies, you can see it's not rocket science. The problem nowadays is finding one part -- the transformer. Most all computers are +5V, +/-12V now, and of course transformer manufacturers gear towards those. Even some of the surplus places I've gone to on the web only have "common" voltages (+5V, +/- 12V, +24V, etc). That's why I wanted to see if there was an SMPS that would do the trick. After looking at SMPS prices, however, I've decided no to go that route. I'm sure they're bullet-proof, and would function admirably, but I'm not going to plunk down $200+ for one :-) (remember, we're talking high current here, not just the little 1A switcher). Anyway, thanks to all ... Rich B.
