I'm wondering if a TRS-80 Model 4 can be converted into a 4D simply by
swapping out the floppy drives. Anyone?
I don;t think you end up with exactly a 4D, but it's certainly possible
to put double-sided drives on a Model 4 (I've done it). You may need to
replace the edge connectors on the floppy drive cable, Tandy did their
drive selection by having missing pins in the connectors, and I think one
that's often pulled is the side select line.
You can also have 80 cylinder drives, but I advise you to keep drive 0 as
a 40 cylidner one (if only becasue you'll not be able to boot standard
disks if you don't).
