This is pretty much what I got out of everything I've looked at. There
were no hooks for adding storage. I just wasn't sure if there was a
common work around for this problem. (As if anything about UCSD is
common...)

This was largely true for the z80based and PDP-11 based versions as well.
I still have the P-system for horizon single density.
The language addressed "units" as devices. The standard ones:
unit volume
--------------
1 console:
2 systerm:
3 graphic:
4 <volume name> system disk
5 <volume name> alternate disk
6 printer
8 REMOTE: system peripherals
9-12 <VOLUME NAME> ADDITIONAL DRIVES
Now if the code for the system interface didn't go beyond 2 floppy
devices your cooked as that was a p-system hard coded thing.
