Hello all, I recently obtained a 1702A EPROM programmer, but it's having some problems. Does anyone have docs or schematics for the following programmer? Tenor Inc, Model 763 Solid State Programmer Other markings: EPROM Loader 763-7-0120, S/N 763 3303 P 1083 See http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1678511077 for pictures. It helps to see the item for the description below... Basically there are 16 switches/LEDs. In Read mode, the LEDs should show the byte values, and in Write mode, the switches select the data, and the LEDs should reflect the data being input. None of the LEDs fire. There is a display for memory location, and it properly resets when "reset" is pressed, and properly increments when "step" is pressed. One other note, the "load" button is supposed to write the data, and advance the memory location display, but the memory location does not advance... I suspect at least the "Read/Write" switch is bad, as it is very mushy feeling, and doesn't seem like it is switching. Perhaps that holds things in some weird state. Standard DPDT, so no big deal to replace. Beyond that, though, I'm at a bit of a loss w/out docs or schematics... Disassembly reveals no blown parts, no smoke marks/burns, and no broken connections.... Thanks!
