I/O Port Summary

Address (default) Address (alternate) Usage
DFxxh N/A Schneiderware RAM/EPROM - Expansion ROM bank number (W)
Battery-backed SRAM and/or EPROM are selected when the bank-number matches the jumper-selected values; the memory is then mapped to C000h..FFFFh (in case of READing one must also enable upper ROM via Gate Array). The bank number decoding is a bit strange:
  • EPROM/Read bank: All 8 bits decoded (bank 00h..FFh)
  • SRAM/Read bank: Only lower 4 bits decoded (bank X0h..XFh)
  • SRAM/Write bank: Only lower 4 bits decoded (bank X0h..XFh)

The SRAM/Write mode doesn't disable the internal RAM in the CPC, so writes are going both to SRAM and normal RAM at C000-FFFF, that no matter if upper ROM is enabled/disabled via Gate Array; the author recommended to map VRAM to 4000-7FFF via CRTC registers, in order to prevent video dirt during writing.
