Been working on making MS BASIC for the 6809 to assemble on modern assemblers; managed to get a script together to correctly prefix all comments in as9 listings.
With a few more tweaks I managed to get MS BASIC to assemble on asm6809, still some clear issues with the origins on old as9 vs asm6809

@ted_dunning @Houl That was exactly the kind of thing I wanted to know. I'm an #assemblylanguage geek. Thanks! I've *cough* spent more time looking at #motorola #M6809 documents today than I should have. Damned ADHD. :-P
Do you think the arch will live on in some way? Even #Fujitsu bailed on it.
Got a new 6809 machine at the weekend... no, wait, a 6309 machine! The future is here. And it runs BBC Basic, with - of course - an assembler built in.
I think I need to write down somewhere an appreciation of BBC Basic's excellent features.
The board is a design by Jeff Tranter derived from the classic 5-chip circuit by Grant Searle.
A green board, 5V operation, through-hole parts, excellent.

Yesterday I started playing with a new single board computer, freshly fitted with a 6309, both board and chip courtesy of @Revaldinho: Youβll notice the board design is by Jeff Tranter, who used Grant Searleβs one-chip glue circuit design as a starting point. And youβll notice the BBC Basic label: Dominic Beesley wrote a 6809 port (and also a 6309 port) and @hoglet crammed a mini-MOS into the same 16k ROM, so the machine boots to BBC Basic. (Jeffβs original boots to Motorolaβs minimal machi...
