This isn't awfully new in the S-100/IEEE696 world; in the 80's Compupro
sold a number of IEEE696 systems that distributed regulated +5V instead of
unregulated ~8V, courtesy of a switching power supply.

To put a "regular" S-100 board in all you had to do was jumper around
its on-board voltage regulators, no big deal.
