On just one breadboard now …

I removed the 32-pin flash and replaced it by an SPI-SD card breakout board.

So it’s only : Z80, Ram and the Cypress 4200 module, the sdcard. A few resistors,..

It runs the Monitor/Basic and CPM 2.2 from Grant’s CPM webpage.

It only started to work today. I will post more later, and put files on github.
