| 5 | 5 | 31/08/2010 Skeleton driver. |
| 6 | 6 | 18/11/2010 Connected to a terminal |
| 7 | 28/09/2011 Added more bioses |
| 7 | 8 | |
| 9 | Some Monitor commands (varies between versions): |
| 10 | |
| 11 | B - boot a floppy (^N to regain control) |
| 12 | E - prints a number |
| 13 | I - Select boot drive/set parameters |
| 14 | K,O - display version header |
| 15 | N - newline |
| 16 | Z - print 'EFFF' |
| 17 | |

| 19 | |
| 20 | I/O ports (my guess) |
| 21 | 30 - fdc (1st drive) |
| 22 | 40 - fdc (2nd drive) |
| 23 | F0 - terminal in/out |
| 24 | F1 - terminal status |
| 25 | |
| 26 | SIO? - F0 to F3 |
| 27 | PIO A-Data 0F4h, A-Command 0F5h, B-Data 0F6h, B-Command 0F7h |
