Hi! What are acceptable voltage supply ranges for an

am assuming 115VAC input. My intended application is a small home

S-100 backplane.
I have seen the S-100 voltage rails vary but I believe +15VDC,
-15VDC, and
+9VDC would be sufficient. Herb's S-100 page lists the voltages as
+18VDC,
-16VDC, and +8VDC but I have seen other voltages used.
Every S-100 chassis I've seen has +/- 16VDC and +8VDC power
supplies, and most of them are unregulated due to distributed
regulation (7805s, 7812/7912 if needed) on each board.
