[Coco] Max number of floppy drives with DOS

[Bill Pierce]

The limitation of the drives (4s - 3d) is actually not just a a DOS problem but it's the logic of the controller itself. There are only 4 drive select lines with the 4th line being used as a side select when doubles are used.
So just changing the rom will not solve the limitation.
As someone suggested, with a multi-pak and 2 (or maybe 3) controllers, you could have multiple sets of 3/4, but you would still have to write a rom (or driver for OS9) that would switch slots when needed. I remember someone here on the list playing around with 2 controllers in the past.
