Korg M1 (c) 1988
Notes:
- Memory cards are branded Korg MCR, one row of 32-pins plus write protect dip
and a CR2016 battery slot, awfully similar to MSX/PC-9801 Bee Card/PC Engine HuCard.
Four known options:
- Memory cards are MSX/PC-9801 Bee Card re-branded Korg MCR-*, one row of 32-pins plus
write protect dip and a CR2016 battery slot.
Four known RAM options:
- MCR-02, 128 kB
- MCR-03, 256 kB
- MCR-04, 1024 kB x 4 banks
- Radiusz Bee-Card, custom made multibank card with rotary knob, 16 x 32 kB/8 x 64 kB/4 x 128 kB
- "Ext. Cards" are coupled with MPC-** (Bee Card) & MSC-** (PCM data) cards, latter is a 19x2-pins
that fits in the back of the synth.
Numbered official releases goes from 00P (factory preset) to 16 + some third party options.
