Restoring a 1976 Wang 2200F mini-computer, Part 1

About this video

Without a microprocessor, this 1976 Wang 2200F mini-computer runs on 113 discrete TTL chips. Episode 1 gives an overview, then takes the machine apart to look at its digital and analogue cards.

Good to know: Mains voltage inside the open chassis, and power supply capacitors that stay charged after unplugging. First of a series.

Why watch it

Parts 2 to 4 are linked, so this overview is where the series begins, and the maker promises a meticulous restoration across the episodes.
