[vcf-midatlantic] Paper tape

Recently, I've been deep into paper tape territory. I exhumed my HP 2748B
high speed paper tape reader, and got it running after a clutch plate
adjustment. It's connected to my HP 2108A minicomputer, along with a 2645A
terminal. I can punch tapes from a Linux system to a GNT-4601 paper tape
reader/punch, connected via serial port. Then load the tape into the 2748B and
read it into the 2108A. They're not kidding when they say "high speed".
So, I'm able to load diagnostic tapes from a very large paper tape library
on Bitsavers. Some of the diags only require front panel operation, while
others need a terminal. There's also paper tape BASIC, which I'll get to after
a connector arrives to make a different terminal cable.
The 2748B reader doesn't have a takeup reel, so naturally the tape goes all
over the floor. Rewinding it is a PITA. I saw a picture of a handheld HP tape
rewinder, and built my own to chuck into my cordless drill. Rewinds even
faster than it spits out!
