Hewlett-Packard 8080A OPT D01 Mainframe, 8081A 8084A 8083A Word Generator, output amp, rate generator 300MHz. This unit was made in West Germany in the late 1980s.
Unit was purchased 25.09.2024 from a reseller in Toronto, Canada for CAD$1440. Unit checked-out okay operationally, then one day it started to smoke...
Quite a complicated affair, including sourcing the part. Farnell has them, but need to find the exact match.
