FoxyLab:
Hello!!!
I want to present to you my vintage computing related project cpm4nano - a complete CP/M system based on Arduino Nano 3.0.
Currently one Arduino Nano in my project:
- emulates the Intel 8080 processor (all tests succesfully executed), 64 KBytes RAM (with two FRAM chips) + 4 FDD (with SDHC card);
- with the help of the PS/2-UART converter on STM8 allows you to enter information from the keyboard;
- displays text information on the TV screen (20 rows with 45 cols) without jitter (with duplication of information to the PC through serial channel);
- receives data from the PC through serial channel (and uploads files from the PC using the XMODEM protocol);
- loads the OS CP/M and runs its programs.

 Needs must - it's like this temporary control panel I had on my model railroad - which lasted until I tore it down to move.
