[GreenKeys] Update - ASR-33 lives

[Jeffrey Golas]

Well an update to my ASR-33 TWX machine that I got a few weeks ago - its alive! I had to replace the motor start cap, and once I did the machine seemed to run (open). I left the dataset power off to test it first.

I removed the boards from the 101 dataset and checked out the power supply - it seemed to be happy and the capacitors held 40+ volts for MINUTES after I unplugged it, so I used a resistor to drain it off, got the boards back in, and fired it up. It now runs in local mode and the keyboard certainly needs help, but seems to be transmitting OK.

I actually connected the modem to a line emulator, and much to my surprise it answered and handshaked from another modem! That said, it was all gibberish so either I need to find a compatible modem or somethings wrong with it.

Either way, very happy so far, just need to go through it, give it some lube and find a way to switch out the loops to use it with other stuff, which looks easy enough.
