I have several, but can only get to a few RS232 readers. If you are
interested
I'll try to get the model numbers later this week.
I also have several REMEX interfaces probably Unibus, possibly a Omnibus.

David Collins of the HP Computer Museum and I just recently completed
reading some 200+ paper tapes from the museum collection. He used a 2748
coupled with a custom A
Further to Dave’s post below, I’m happy to share the Arduino code and schematic
if anyone has a suitable reader and wants to try it. It was indeed designed to
