> Doug, what does the nomenclature plate on your 6-bit units say? Does it say "BRPE8 6"? do we know what an 8-level BPRE name plate says?

I've transcribed all the nomenclature here:
-- https://homepage.cs.uiowa.edu/~jones/pdp8/UI-8/guide.shtml#BRPE

I summary, it says BRPE18 on the front.  No spaces.

And, wonder of wonders, after struggling with many small fiddly bits, I managed to reassemble all the toggle links, drag links and blocking pawls of the machine I'm working on, widening that part of the machine to 8 bits.  Still need to reassemble the eccentric that wobbles the whole mess up and down, but everything moves smoothly.  After that, I'll need to salvage two solenoids from the parts machine and move them -- I know which ones to take, and then wire them in.  The wires are there, the factory taped and tied off the extra wires.
