This is David Hansel’s Disk Controller expansion board for the 26-pin bus. You can read more about this board at David’s Github.

This includes the circuit board and all necessary components, including an ATMega328p programmed with MITS firmware, to replicate the function of the MITS 88-DCDD 8-inch and 88-MDS (Minidisk) 5.25-inch floppy disk controllers. You will need to provide a compatible floppy drive, power supply, and cable. No additional instructions are provided, you will need to follow the Github and OSHWLab pages for construction.
