H.M - When selecting files on an A1200 (and a '030 expanded one at that!) with the keyboard, it is very easy to select the .ADF and automatically select 'SAVE & REBOOT' on the next screen.
You have to tap the ENTER key very quickly. Otherwise the MENU goes to the second screen for allocating the ADF to a file slot so quickly it has already selected REBOOT.
If adjusting the timing in the MENU PROG is tricky, how about a 'dummy' line on the SECOND page of the MENU, so if it does jump to the SECOND MENU PAGE you will not REBOOT the computer. You would just press down once for SAVE & REBOOT and down again to the part where you put the ADF into the required SLOTS.
