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.
