You'll be lucky, 2708s are a pig to find and even worse to program!

What makes you think it's the PROM that's faulty?

Ben at Cyber wave is working on it for me and he asked can I get access to this item I'm not sure it was very sick needed a new CPU and some of the patterns  weren't working he has fixed all that and now he's working on the programmable patterns so I assume it's got something to do with that

I fix one today, power supply problem (bridge diode), change 2 mc14175b, the battery make corrosifs on traces printed board, 2 days of work. And it's ok.  The CPU and Prom are ok.  Be shure for the problems. A+ :)
