[GreenKeys] Selector Magnet Driver circuit for DOVETRON Tempest units?

[Ralph Irish]

Did someone come up with a fairly simple circuit to be added onto or wired inside the
DOVETRON Tempest TUs?  I have a line on one and know that it will not work as it came
from the factory to directly drive a teleprinter at 60 ma or 20 ma.  

If someone has come up with such a circuit, I would like to know how to get it.  A 
PC board layout would make things even easier.

Thanks,

Ralph - W8ROI
