@fae @lynn The S-100 bus power supplies were nominally +8V, +16V, and -16V, filtered but unregulated. Each card was expected to have linear voltage regulators from +8V to +5V, and, if needed, ±16V to ±12V. The more cards in your system, the more amps of each supply you needed, though the "1400 amps" in the song is gross exaggeration. Early Altair 8800 systems, and some others, had small backplanes with few slots, and were provided with wimpy power supplies. 1/
