SC127, v1.0, Description

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
