Disappointed that no one responded to my question but glad they did on the Data I/O site and landed up buying a used Data I/O Labsite.........Sorted !

Hi All, I need to program some vintage 82S129 bi-polar proms and can't find a programmer capable of doing it now. I was wondering if I made an adaptor on overboard to 'fool' a programmer into thinking it was programming a modern eprom but am unsure of timing, algorithms etc. Any advice appreciated. ...
