SC127 is a Compact Flash interface for the Z50Bus.
Actually, this card provides an 8-bit IDE interface via a 40-pin male header. In theory, you could connect other IDE devices, not just the recommended Compact Flash adapter module (shown above).
As this is a very simple interface, which uses the processor bus directly, without buffering, the IDE interface should not be extended for than a few inches and only carefully selected devices should be connected. In general, it is best to only use this interface to connect a Compact Flash card.
The main features of this card are:
- Z50Bus compatible (“Standard” card size 100mm x 75mm, but with a cutout for the Compact Flash adapter module)
- Tight address decoding
- Choice of two I/O addresses
- Jumper for optional power to IDE connector
- Activity LED
