I'm happy and have current time to do a PCB layout, and I suppose such a 
design might match demand.  My main concern with a 6532-based approach 
is the long term viability of sourcing 6532 ICs.

I agree, in place programming would be more trouble than value.

I'm game to design and run a small run of boards, just let me know.
