Wang 2200 basic computer from 1975

Short demonstration of a rare Wang 2200 (SE2) basic computer from 1975. Still working nicely after 42 years. Doesn´t have a microprocessor, processing is handled by hundreds of TTL-ICs inside a separate huge “black box“, which includes also the power supply. In this video, you can see the terminal 2216 with built-in tape drive 2217 and the keyboard 2223.
