That's cool. I need to scrounge around and find my copy of Forth we used on a 6809 tape controller firmware. I had forth in the diagnostic firmware that we had on a snapon module and you could compose whatever diagnostic exercises you chose by executing the basic
test functions we had in Forth.
Thanks for posting and finding it or writing it, Eric. thanks jim On 3/27/2017 10:51 PM, Eric Smith via cctalk wrote:

The documentation that came with it stated: Written for Motorola by Joel Boney, 1980 Released into the public domain by Motorola in 1988 Docs and apps for Tandy Color Computer by Rich Kottke, 1989 What I haven't been able to find is the actual *source code* to the module. Is it available anywhere? I've been playing around the the MC6839 on an emulator but having the source would clear up some issues I've been having with the code.https://github.com/brouhaha/float09 I haven't modified it to assemble with a readily available assembler, so I don't know whether it assembles into the exact MC6839 ROM image.
