<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.
