I have Motorola's "linear circuits" and "interface circuits" from 1979, but
actual Semiconductor Data Books I only have are from 1969-1973.

Randy, if you're looking for Moto databooks, Al has archived a pile of
them on bitsavers:
'80s Motorola Semiconductor Reference - anyone?
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

Not directly useful for part number interchange, but schematic and
mechanicals for the 3T series switching regulators here:

Annoying, but I still appreciate the tip. I think I can get where I need to go
with the assorted Boschert manuals on Bitsavers, if I put the effort into
tracing mine out.
Tony forwarded me some schematics which i've added to

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

if you do trace it out, I'd like to add it to bitsavers.
there aren't many boschert schematics on the web

Until someone comes up with a better theory, yes. Consider this supply:
