I am working on the Submillimeter Telescope today, fixing a fine old
German instrument.

I found a parts cabinet with TTL part numbers on all the drawers.

Here's the 7441 Nixie driver drawer:

Yeah, be careful with those ones, David. They look like the lower voltage types.

To be fair, though, they look like they can take pretty high current.

Wow. Screwed again! That's about like every time
I walk in to Skycraft in Orlando, FL and walk back
to their drawers of TTL. I always check the drawers
labeled 7441, 74141, 74142....and I always see the same
old dust in each of them, but no ics.

However, checking the 4500 drawer, I found it slam full!!
Bought 5 of them, and have yet to fire up a 4500, but
am planning to when I have some time. 4500 is a one-bit
16-instruction processor. And, here's the best part
about it: It can run at a clock speed from DC to 1 mHz.
I like the DC part. (can you say push-button?)

I'd suggest you bolt while you still can!

I was browsing the board, when I saw you post about Skycraft.  I live in Okeechobee, Fl and have been planning on visiting my daughter in Orlando.  Now I know where I can go while mom and daughter start gabbing.  I love surplus places, and I have been looking for an electronics surplus place for a long time.  Thanks for posting this.
