[GreenKeys] PDP 11/05 to ASR 33 Update

[billdeg at aol.com]

Just a quick note of thanks for anyone who wrote to me about the reader control question I had, and in general about the process of hooking up a PDP 11/05 to an ASR 33.

The connections I have are 

Transmitted data return (-) attaches to terminal strip screw 6 or "number 2 connector" #7 

Received data return (-) attaches to terminal strip screw 3 or num 2 connector #5 

Transmitted data send (+): Terminal Strip 7, #2 connector 8 

received data send (+): Term strip 4, #2 connector #6. 

I now have a stock full-height version pdp 11/05 with M9970 wired to the teletype.  When the computer is powered on, the teletype in LINE mode comes to attention.  I reproduced the connection on another teletype to be sure the result was the same on both.

I have the PDP 11 docs and now I have to work through the I/O processing now that the physcial connection is done.  

Best,

Bill Degnan
