[GreenKeys] Off topic: variable transformer

[Paul Heller]

What am I working on? One of these: https://en.m.wikipedia.org/wiki/IBM_5100

And one of these: https://en.m.wikipedia.org/wiki/HP_series_80

They were given to me about 15 years ago. The IBM had been recently powered on a the time. I don't know about the HP. 

Thanks again!

Paul
