Looking for EPROM 2708 help

Is there anyone out there that can BURN a 2708 EPROM for me. My Data I/O System-19 W/UNIPAK is DAS Kaput. It will not burn me a good prom. Not Sure why though. My Fault ???? I am trying to add some code to Dave Dunfields Monitor to find out why the 2708 that Andrew burnt is malfunctioning on my N*. I have tried to add several lines of code but the resulting Prom just doesn't perform the way the Andrew Prom does. I am using a SOL-20 System/Bus Probe that will Single Step the N* CPU so I can then track the code and its execution. I can see the results of the OUT 3 & 2 Instructions but not the IN 2. I am going to add jumpers to the Probe to display "Data In" as well as the existing "Data Out" and that might help. I have at least 5 2708's and can mail one out then I can sent the Code as an attachment. ALSO is there anyone out there using Dave's Monitor Mapped at "0000" that would be willing to test the 2708 that I have; that works somewhat; that way I could determine if the Fault is in the N* or in the Code itself. Since I can't burn a New Prom I am up the creek without a Paddle so to speak. TIA Bob in Wisconsin
