A memory expansion is not hard to implement. If its a stack of 2114's you would just be a rotary switch clearing the various CS- lines. If it was done with a larger dynamic RAM, then some cascade logic. This is not a battery backed sequencer so I would think it would be of limited use to me. I suppose it would not be a big deal to use SRAM and then battery back it. Oh no... I am getting mod fever!
