Mystery 1702A(?) EPROM Programmer

[Jonathan Chapman]

Reformed the big capacitors, tested the power supply, replaced all electrolytics on the control board (two were leaking) with hermetically sealed axial tantalums, and powered up on the variac today. Seems to be largely working at least for reads!

Thanks,
Jonathan
