Casio Collectors

Hi everyone,

I have two FZ-1 samplers, both without the expansion to 2MB and that's something I'd like to change in the long run. So I was thinking if someone here might have build their own 1MB expansion board and what types of DRAM they had success with. I'd hate to find that once I go out and buy a 1Mx16 DRAM (or an ensemble of smaller DRAMs that give the same configuration when suitably combined) that there are problems, e.g. with timing, logic levels or supply voltages.

Thanks,
Thomas
