Teletype Model 33
This belonged to my Dad. I remember playing a lot of Startrek(.bas) on it when hooked up to the 'ol Imsai. I'd sure like to get it working. One problem I have with getting it working is I left it behind when I moved! (S/N xyz. It's in storage where I can't get at it at the moment.) I would also be nice to add paper tape to it too.

Wanted to buy
- Roll(s) of paper tape
- Typewheel hammer ?felt?
- Call Control Unit plate under rotary dial with holes for buttons
Goals
- Restore to operation as an S-100 computer interface
I've got parts to make a 20ma current loop to RS-232C adapter, but hopefully will be able to resurrect something like an Imsai SIO S-100 card in current loop mode for authenticity.
Restoration History
- 7/30/2015 Retrieved my Dad's KSR and bought an ASR on the way home.
- 8/4/2015 electronics details
Apparent current loop cable is attached to pins 1,2 and 7,8. There had been a DB25 connector on the bare end it's fallen off over the decades since last use.

I need a spring to hold this bar up. I think it's called a "Function Pawl" Section 574-122-100TC
