Anyone have an early ?80s Motorola semiconductor
reference manual? I am attempting to repair a Boschert power supply from ~1983 that is
full of Motorola parts marked as 1027 (DO-42ish), 1077 (TO-3ish), 1078 (DO-5ish), etc. It
would be extremely helpful to know their specifications, or ideally how to cross-ref them
to ?standard? parts.
Those are Boschert "house numbers'. Unless you can find a Boschert
maintenance document that lists them and ther equivalents, it's going to
be a bit of a detective sleuth.
Ugh? I hadn?t even thought of that. You?re confident of it?
