Move SD Card subsystem outside of RC2014 recipe and add protocols Although the SPI Relay driver is RC2014-specific, the SD Card driver is generic enough to be a subsystem. That's the second subsystem we add and this warrants, I think, the formalization of a new concept: protocols.

Make the SPI Relay protocol support multiple devices Working on programming AVR chips exposes a glaring omission in my first design of the SPI Relay: not allowing multiple devices make this task hard. I constantly have to unplug my SD card before, plug the AVR chip holder, then play a bit, then unplug the AVR holder, then replug the SD card... My prototype for a SPI relay design is built, but I haven't tested it yet. I need to adapt the code first, which is what I do here. When the prototype is tested, I'll update the SDC recipe with a new schema.

  1. SD Card subsystem

  2. 

  3. Load range: B423-B436

  4. 

  5. This subsystem is designed for a ad-hoc adapter card that acts

  6. as a SPI relay between the z80 bus and the SD card. It requires

  7. a driver providing the SPI Relay protocol. You need to define

  8. SDC_DEVID to specify which ID will be supplied to (spie).

  9. 

  10. Through that layer, this driver implements the SDC protocol

  11. allowing it to provide BLK@ and BLK!.
