Of course, that is what I do as well. But when I want to access the disk
(BDOS), I need to have the bios in page 0 (or at least the slot switching
routines). I don't have them in my own 0-page code, or at least not in a
dos-compatible way. (They will be dos2-compatible, but they don't switch
the usual way on rst 20). So does the BIOS always switch 1's in the
buttons and a 0 in the strobe, or is it random?
Thanks, bye,
