I've got one of these--actually a no-name, but the same Taiwanese unit. At one time, I think these were also sold under the "Sunshine" name. You could get them with different "heads"--anywhere from a single ZIF socket to 8 or so; maybe even 16. I have the 4-socket version. You've answered your own query. This board is strictly 5150/5160/XT clone territory. IIRC, even a PC AT doesn't work--at least with the software that I have (I haven't tried JDR's). I believe that this is due to many CPU-based timing loops. I remember patching the code to detect the board so it would run in a 386/20, only to have it fail to program EPROMs, whereupon I gave up and stuck it back in the XT, there to stay until the present. This forms the basis of my suspicion that CPU loops are used exclusively for timing--not a really bad idea back when the world was filled with 8088 systems. Certainly, it wasn't alone in this respect. Get that 5160 going and you should be fine. I suspect though, that you're faced with a chicken-and-egg situtation--you need to get the EPROM burner going so you can get the 5160 running. Source code for the programming software should make things easier to modify for faster machines, but I suspect that it's unobtainium. Disassembling is another option, but not one that I'm interested in, as I have a parallel-port driven programmer that can still handle the older EPROMs just fine. Cheers, Chuck
