I don't know whether you'll have much luck finding a 6809 board for S-100
bus.  The ones I recall were

1. Logical (Systems?)--a Florida company that also made ROM burners.
2. Ackerman Digital--an Illinois outfit.  They had a 6809 board, no memory
   mapping so that you were limited to one 64K address space, and they ate
   4K of that by not bothering to decode memory-mapped I/O to their two or
   three on-board ports very well.
3. MicroDaSys might have had one, but my memory is very fuzzy; I don't know
   for sure.

I don't think any of them did memory mapping.

I think you'd have better luck finding a 68000 board for S-100.  Cromemco
(the folks with the infamous S-101 bus, the 1 being some kind of wire
running across the top of the board if I remember rightly :-) made some,
and Godbout might have made one.
