om...

Comes from never throwing anything away. I've still got my 1985
Signetics Linear LSI Data and Applications manual (because it had so
many app notes).


I have the same affliction. I still have apps & data books going
back to my 1973 National Linear Apps Handbook.

That beats my 1964 G.E. Transistor manual.


I'd be very interested if anyone has any old Mullard data sheets; OC, AC,
AF
etc.


Sorry, don't have any Mullard.

Does ring a bell though. Back when I was a young whipper snapper I
might have used one of the OC line in a 'talking on a light beam'
science fair project but all I can remember is the 'cost saving trick'
was to scrape black paint off the transistor body so it could be used
as a photo transistor. Sounds like maybe an OC7 (or 71, 75, etc).


A common trick with the OC71 but Mullard started using opaque grease to
protect the substrate assembly.

I have a small stash of NOS genuine OCP71s.
