[GreenKeys] Speaking of ebay

[Paul Heller]

Well this is encouraging!! I have a TWX machine and the pedestal has the 101C in it! It was a mouse machine when I got it but the damage was minor as near as I can tell. 

Might have to give it a try.

The circuit I used provides optical isolation but that's really not necessary - the 101C has very nice +/-20V power supplies; my circuit requires a separate 5V supply on the computer side.  Overly complicated, but  that was just my mindset carrying over from working with my Model 15's 60 mA loop.  Been meaning to simplify the 33 i/f, but inertia being what it is...
