Memory card locations are special, meaning they aren't EMCA slots.
You can fill up all of the memory slots and still have all of your
slots free for adapters.

I can't answer 1), but I can answer 2) and 3).

The SCSI adapter does sit on the MCA bus.  It has a connector on the
back end of the adapter, which is available to connect anything you
want [ more or less ].

To connect a new SCSI device, power off the machine [ duh ], cable up
the new device [ making sure you don't duplicate any SCSI addresses ],
and re-boot.  The machine should locate the new SCSI device when it
configures itself.  There is a "Hardware Quick Reference Guide"
which gives LED values [ numbered 800 and up ] for the different
devices.  Look up your device in the back of the reference guide and
you should see your device ID flashed on the LEDs while it is being
configured.

DISCLAIMER: I don't speak for IBM, and they don't speak for me.
