It appears that it's a ROM card. You either write your ROM to the 6116 ram and back it up with the rechargeable batteries, or you can burn eproms and insert them. If I can adapt it to larger ram or Eproms, then it will be a nice card. Otherwise, I have a FlashROM card that can go up to 512K easily enough. What good is 16K in this day and age, when larger ROM cards are possible?? :o)
The capacity limit will depend on the decoding and bank select logic on the board. Given that it was intended for 2KB EPROMs/SRAMs, it would be surprising if it went much beyond that. All addressing of the on-card memory must be "windowed" into, I would guess, the 2KB I/O extension space on the Apple II, from $C800 to $CFFE. -michael New Applesoft BASIC interface for NadaNet networking!
