Does anyone know if all 16 address lines can be used on the memory slot? A
IIGS with 64MB would be nice, but I have always heard that the max
addressable memory was 8MB. Is the upper portion of memory reserved for
anything? Or does the ROM just not support it? If anyone knows, please let
me know.
By the way, I am nearly finished with my 8MB memory card design. So far
it uses only 4 4Mx4 SOJ's and a handful of gates. When it is tested, i will
post the schematics. The nice thing is, it can be built with only about $30
worth of parts and a 16MB SIMM (to scavenge for DRAM's).
Thanks in advance for any help!
