In this video I deal with an unusual problem in the HP9845B vintage computer which I am restoring. The processor hybrid modules appeared to be dead but are they?
Note that this footage was shot early in the restoration process but I decided to post it as a separate video so it may seem out of sequence with the rest of the series.
