Apple IIGS: How to Mix a 3.5-inch Drive with Other Drives



I am using an Apple IIGS with a DuoDisk drive and a single 5.25-inch drive.
The controller cards are in slots 5 and 6. I want to use a 3.5-inch drive
along with the other drives. I installed an Apple UniDisk 3.5-inch drive
with its controller in slot 4 and tried slot 7 with no success. I changed
the slot settings under the Control Panel each time. How can a 3.5-inch
drive be used with the described 5.25-inch drives?

Try this configuration:

1) Plug the UniDisk 3.5-inch directly into the back of the computer (no
controller).

2) Plug the DuoDisk into the port on the UniDisk 3.5 disk (no controller).

3) Plug the single 5.25-inch UniDisk into a controller card in slot 7.

Set the Control Panel as follows:

slot 5 smart port
slot 6 disk port
slot 7 your card
startup scan

This configuration tries first to start up from the UniDisk 5.25. If no
disk is found, then it looks to drive 1 of the DuoDisk. If no disk is
found, then it goes to the UniDisk 3.5.
