I've got an ALS "The CP/M CARD" together with all the documentation and CP/M
3.01c. I intend to upload the disk images, but I have a flight to catch in
two hours and I'll be away for a week, so if you have any more questions
don't expect a reply for a while :)

Slot 4.

Set slot 4 to "Your Slot" and set the system speed to "Normal" i.e. 1 MHz.
You'll need to reboot too for the changes to take effect.

No, at least one of the disks should be bootable.

No, just booting from the disk should enable the card, it should also give
an error message if it can't find the card.

Starting with 3.01c the software adds support for running from a disk image
on a ProDOS disk drive. This is very, very cool. You can boot into ProDOS,
then run a ProDOS system program which loads the CP/M boot files and starts
CP/M. ProDOS stays in memory and CP/M uses the ProDOS drivers for the clock
and disk drives, including 3.5" floppies and RAM drives. When you're
finished with CP/M you can quit back to ProDOS without rebooting.

It doesn't work as well on a IIgs though since you need to set the speed to
slow and turn on slot 4 every time you want to use CP/M. The other problem
is that the software was originally designed for installing to a ProFile
hard drive in slot 5. It works fine with an Apple SCSI card in slot 5 too,
but then you lose the 3.5" SmartPort. Fortunately it also installs fine to a
3.5" floppy drive, and 800KB is more than enough space for most CP/M
software.
