[GreenKeys] Got new Teletype writer,need help to make it work.

[Jason]

Hello ,I just got a teletypewriter ,it seems to be a imitation of RFT T51
which was an imitation of  the Siemens T37.
I love these mechanical computing things,and want to make it work again.
I'm trying to make a ttyloopdriver
<https://github.com/John-Nagle/ttyloopdriver>(
https://github.com/John-Nagle/ttyloopdriver) to connect it with my
computer.But because of lack of hardware design knowledge,I encountered
many problems.Last night after running awhile I saw smoke rising from the
motor remote control part.
Another question is this one needs 40mA current to work,I want to know what
if line in a 60mA current loop which is supplied by ttyloopdrive board.

the motor runs with sparks in the carbon brush.
