Someone a while back offered to help with questions I had regarding reinstalling a touchtone keypad I foolishly removed from an ASR33 while trying to convert it from 110 baud dataset use to current loop. I just located the keypad this weekend. I have two here, same era, different connections. ISTR that the one with more leads came out of the ASR33. Here goes... Number one: Top marking - 35Y3D 4-77 Under the "3" button - red w/green stripes Under the "2" button - red, black, orange w/black and white w/blue (4 wires) Under the "1" button - green and blue (two wires) Under the "6" button - white for a total of 8 wires Number two: Top marking 35AF3A Under the "3" - black jumper, purple, red w/ green (2 external) Under the "2" - green w/white, red, white (3) Under the "1" - black, orange w/black, white w/blue (3) Under the "5" - orange Under the "4" - green Under the "*" - blue Under the "#" - the other end of the black wire from under the "3" For a total of 11 wires. I would appreciate any information or leads to information about Western Electric touchtone pads. The plan with the ASR33 is to set it up on a phone line simulator with a 110 baud modem on the computer side, driving the teletype through its original interface. Much less work that grubbing around inside the TTY to install a current loop. I already have the simulator. We used to make them at a place I used to work at. I have the last run of bare PCBs and enclosures, etc. They were 8048-based, and simulated failures as well as successful calls. I used one once to add V.22 synchronous autodial support to our HASP and 3780 products for the VAX (thus keeping it within the 10-year rule). Thanks, -ethan
