This is a great product which I have used to program many eproms over the last year. Unfortunately this morning one of the Address lines (A14) has failed, I guess maybe a bad Eprom was inserted on my part. I have isolated the fault to CPLD U6. A pin has a 79 ohm short to ground and the pin has trouble producing output. The programming fails on verify at 0x4000. Is it possible to order a spare CPLD to fix my programmer?
