If the 6702 is nothing more than a dongle, then it is most likely a logic array. Checking my old data books, I find the Monolithic Memories PAL 20 series. These have enable on 1, ground on 10, clock on 11, VCC on 20, inputs on 2-9, and outputs on 12-19. If you switch the inputs with the outputs, you have a 6702. This should be easy to crack. Pull the daughter board, put a test clip on the 6702, and wire lines to an eprom programmer, and read it out like a 256 byte ROM. wlevak@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org Message was sent through the cbm-hackers mailing listReceived on 2012-02-12 04:00:08
