[GreenKeys] Model 33 ASR (ASR-33) Parts needed and questions.

[Mike Katz]

I was recently given a Teletype Mdeo 33 ASR (model UK800DRA, serial 
#245210).

This unit has been modified for for RS-232 with a wire wrapped perf 
board in the call control unit space.  I believe that during that 
conversion the Reader Power Pack was removed (it isn't in the stand either).

I have been able to send and receive data from the ASR-33 to a VT-330+ 
terminal set to 110 baud 8-N-2 so the keyboard and teleprinter are 
working.  The punch seems to work also.

I have some questions:

Can I used the Automatic Power Pack (183079) with a reader that was not 
designed/wired for it.  The reason to do that is to connect the relay 
control input to the reader run control of the PDP-8/E M8650 
Asynchronous board.

Looking at the schematic for the 183087 Reader Power Pack board should I 
assume that T1 is connect to the 110 AC hot and that T2 is connected to 
neutral?  If this is the case I could possibly build one of these.

I am looking for the following parts for the ASR-33.  Please contact me 
if you have any of them.

reader power pack (183087 or possibly 183079)
rubber hammer (180502)
paper spindle (181043)
paper tape spindle (183918)
paper tape ends (182935)
chad box (182924 or 182965)

Thank you,

                Mike
