I have a model 33 ASR that has been modified for RS-232. I am not sure
exactly what has been done without taking the RS-232 converter out of
the machine and risking breaking something undocumented.
I have both an Automatic Reader Power Pack and a Manual Reader Power Pack.
The model 33 does not have an automatic reader installed.
I will be connecting the model 33 to a PDP-8 which uses reader
start/stop control via a custom DEC board installed into the model 33).
I can't just plug the automatic reader power pack because (i believe)to
the manual reader because the manual reader is missing some wiring and
circuitry.
Is there anyone out there who has an idea how I can remotely start and
stop the reader using a currently loop output from the PDP-8?
I already have the PDP-8 working on the PDP-8 without reader control.
Feel free to reply directly to bitwiz at 12bitsbest.com.
Thank you,
Mike
