A complete bus interface design and floppy drive emulator for the Tandy Color Computer using Arduino/AVR!
This is a combined open source/open hardware project to design a development board for a variety of 8- and 16-bit computers, starting with the Tandy/TRS-80 Color Computer.
Videos of how these components work together are available at https://www.youtube.com/user/Greyhound716.
Directories:
firmware2 - AVR gcc project for the firmware to act as FDC and ROM programmer. fpga - Altera Quartus project to implement the control logic for the board. kicad - Kicad project including the schematics and board layout. cpld - Some legacy stuff, for some earlier attempts to build the logic using small CPLDs.
