[Coco] Multi drive controllers

[Bill]

I know I can run the 5 1/4", as 2 drives (drive 0 and drive 2), and the 3
1/2" as a single sided drive (drive 1). I have no way to hack the other
controller. Can the I/O address be changed by a POKE?

If you're asking about running all three drives off one floppy
controller, you need to make sure each drive has a different number
and have a cable with enough connectors.  I've run my CoCo with 2x
5.25" drives and 1x 3.5" drive for years.

If you're asking about using multiple floppy controllers you'll have
to hack the hardware to change the I/O address on the second
controller.

BTW the limit per controller (without hardware hacking) is 3
double-sided drives or 4 single-sided drives.  Tandy wired up side-select
and drive-select in a ....unique.... manner.
