Hope someone build one USB rom emualator for openmarket.
What is the minimum useful size? Would 2Mbit be enough? Can anyone suggest a reasonable target price?
A USB micro, SRAM and some mux chips is really all that's needed. Maybe even use flash in the emulator. But to have an upgrade path and best configurability would probably require a PLD. (So that one hardware can do both LPC and parallell, and maybe even 3V3 but still be 5V-tolerant.)
