Wow! If it was black, it would look just like a unit I dumped on ebay last year!
Mine was probably much older (mid 1970's) - based on a generic Intel 4004 processor board. Actually sold pretty high as people wanted the Intel 4004 board and not the rest of the unit.
As far as this programmer is concerned, I would ask seller questions such as software needed? If so, is it included? Does it work with newer operating systems? What parts are supported.
Looks like it comes with two 0.6" adapters and two unknown adapters on the right. Many parts such as PROM's and PAL's/GAL's come in 0.3" configurations.
