The SF3 can now (recent firmware!) emulate the Dobbertin HD20 hard disc.
Therefore I made an 21 MB Image with:
- CP/M Plus + Apps
- Z3Plus + Apps
- 63 KB TPA CP/M 2.2 + HD utilities
See manual and have fun! :) :) :)
Another great piece of software supporting the Dobbertin HD20 hard-disc - and this way usable by owning an SF3:
