Re: Four drives on a Disk II controller?

[A2Aviator <a2aviator@gmail.com>]

Rana and Concorde, are two four drive controllers. I modified one of
those Rana cards back when to do 8 by flipping one more bit, the
drives on a Disk II card are hooked in parallel except for he head
select. With DOS patched to take more than 1 or 2 for the drive
argument, it just means some way of reading the location to toggle
which drive gets the head/drive select enabled. Thats the one that the
motor will come on.

The DOS patch in simple is changing the max value to be what you need
it.. Beneath Apple DOS should have the answer there, as to the
location.
