   @trcwm No, i didn't know that podcast. This is the board i am using:
   https://github.com/Z80-Retro

   It's a rather simple SBC with Z80, CTC, SIO, 512k RAM and 128k ROM, and a questionably implemented SD card interface that shares an IO port with the RAM banking.

   The original designer wrote a CP/M 2.2 BIOS for it, and I took that as a start to write a CP/M3 BIOS. The only thing left from the original is the SPI code for the SD card.
