IMHO it is doable but would it > create enough interest? 6809E are typically available from synthesizer parts sellers as it was used in several 1980's machines. And then there's System09, a compatible VHDL model of the 6809: http://members.optushome.com.au/jekent/system09/ OHO-Elektronik's GODIL module even makes drop-in replacements for ancient 5V technology possible: http://www.oho-elektronik.de/pics/UM_GODIL.pdf What is really scarce, though, is the 6309(E), i.e. Hitachis improved version of the 6809(E). You probably have to recycle Yamaha DX7s for harvesting these... > Software shouldn't be a problem IMHO: FLEX. Plus, 6502 and 6809 are almost sourcecode-compatible, so anything which was written for 6502 could be (unelegantly, but easily) automatically converted into 6809 mnemonics and reassembled.
