It works out there's 1k more useable ROM space than the older CPU.

I'll use it if I need to. Fortunately SDCC 2.4 (the C compiler I use to
build to P3 firmware) produces noticably more efficient code than the
previous version. The current P3 test build is at 469 pages of a possible
492 in the original CPU, or 500 in the newer (pages being 128 bytes). So
there's plenty room for the time being.
The current release build is smaller than the test build too - I'm working
on a simplified playlist edit mode, and transmission of controller messages
from the knobs in play mode.

If it comes to the point where the code size exceeds the capacity of the
older CPU, and someone wants to upgrade, I'll be happy to supply a CPU
upgrade for minimal cost.
