Hi,
Disconnected new HDD, and floppy still did not work.
Found some "thing" on the control board that were not working, replaced them, now floppy works.
But new HDD still does not work.
Nor does the keyboard format it straight away. Do you know if ther is there some way to "manually" format the drive by pressing the menu buttons? I have looked but cannot find a way.

The new HDD is recognisable when it is connected to a PC, so I know it works and is not damaged.

Thanks for your help anyway.
