2708 EPROM progreammer - old magazines designs

[Steve Robertson]

I recently bought a "Willem" programmer off Ebay for about $50. I've been
using it for 2764s and 27256s. It does a lot of different ROMs including (I
think) 2708s. It beats the crap out of my old, tempermental, PIA, Prolog
programmer :-)

Highly recommended.

See ya, SteveRob
