Mystery 1702A(?) EPROM Programmer

[Jonathan Chapman]

I assume the box is just a somewhat generic project enclosure, similar to standard offerings from Bud, Hammond, etc.

I'll go through the power supply tomorrow or Monday and see where I can get with read mode. It looks like writes should be hardware timed, so that's good news!

Thanks,
Jonathan
