<Has anyone ever upgraded a memory expansion card (000034, plugs into <slot 0-5 of the CTI bus) from 64Kbit to 256Kbit chips? (256KB to 1MB) <You can easily do this with the memory card that plugs into the <mother board--there's even two empty jumpers waiting for stuffing. No. the other board is also very different. <Is it possible? If someone thinks they can do it, I'll gladly <contribute a board for a proof-of-concept test. You keep the board <as long as you tell me how to do it! Yes, you will need to alter the PALs and also configure for an extra multiplex address line. Practical, not likely. Allison
