Talk about flash·backs…
"they made their own power supplies back then – huge metal boxes with a massive transformer that had about a hundred secondary taps and took up half the case." … A lot of things needed —12V back then and shunt regulators waste perfectly good electrons. Laminated steel core transformers; none of this effete woke switch mode nonsense. ;)
"the cases all had fat, chassis-mounted diodes and smoothing capacitors that filled up most of the rest of the case. And they'd always output oddball voltages, like 27.3 volts – at 87 amps."
In retrospect seem hardly credible in the age of cloudy oversell and misrepresentation that then "we did get to see the hardware, and it did what it said on the tin" even if it required a new utility substation, removing an exterior wall and hiring a forklift.
"the uninsulated mains bus that ran lengthwise down the inside of the case. Life was both simpler and cheaper back then..."—and occasionally shorter.
