Polymodular CPUs

[The Proteus]

I've been seeing a lot of talk in the past day on this Polymodular
project, and I can only assume that it's a digitally controlled analogue
modular. Hope I'm not totally off my rocker on this assumption. Anyways,
I've got some comments on the CPU selection below. 
	If we're looking at a 6502 class CPU, why not the Motorola 68HC705
series as well? The 68K is a good choice, but bulky. The advantages of
the '705 are single-chip systems, and there are about 50 to 100 devices
to choose from with various onboard RAM/ROM, serial, timer, and
A/D<->D/A options. 
	One of the older modular designs I worked on in '95 used a 68340 as the
core CPU, and then every module had a 68HC705P9 on them for digital
control. Since they cost something like $2.50 each, it wasn't that great
of a cost. The '705 series could also solve the optical front panel
problem as well, since you take a distributed processing approach. 
	If anyone wants to pursue this, I have tons of information on these
little CPU's. Let me know! :-)
