This is the port of the Tatung Einstein TC01 & 256 for MiSTer FPGA by Pierco (Pierre Cornier).
Insert a DSK file then press CTRL+TAB to load it. Use the DIR command to list the files if it's not a bootable disk. If you want to run a COM file, just type the name without the extension and press the [ENTER] key. For XBS basic files, you will need to load the XBasic first (insert the disk and type XBAS), then load your XBS file with LOAD "filename" and type RUN.
I want to thank Stan Hodge and Alan Steremberg for their help! And I would also like to thank Fabrizio Di Vittorio for allowing me to include his diagnostic ROM with the core. You can enable it in OSD.

The diagnostic ROM will fail at the floppy disc controller.
- PIO connected to port M001 for printer.
- PCI for serial communication.
