Forgot to mention, I have a 2382A that works (affectionately known as the
"Munchkin" terminal). I could measure some stuff in mine for comparison if that
could help out.
For the HP curious, the 2382A makes an appearance at the end of one of my videos:

It is very cute (I think) ;-)

Can't find it either in any of the X-ref lists I have. As you know already, 1854 are
usually NPN transistors, but around these numbers I see mostly Darlingtons in my
collection. So maybe that's what you have, and why the junctions would test weird.
