Re: Slot settings on a ROM 3



Technically, you should not issue a blind call to the PR#3 routine
either. According to the old Apple, this is bad programming. For one
reason, there is a switch on the //c which controls the 80/40 column
output. If you are looking for an approved method, check the //c
utility disk or the early IIe Prodos utility disks with the BASIC
versions of these utilities.

Actually, you should check the machine type you are running on, and
then call a m/l routine which will scan the slots for a video card.
This routine can then call the init code or return the slot value to
the caller who can then deal with it as necessary.
