Having learned assembly language programming on the
beautifully simple architecture and instruction set of the 6800, the Byte magazine article
linked to below that I read when it was originally published really impressed me. In the
6809 they made one of the earliest efforts I know of to really tweak an already great uP
instruction set based upon an analysis of existing software:

I was introduced to the 6809 when I was at university and it just seemed
right. I came home and bought a CoCo2 and an EDTASM+ cartridge just to
play with it. I still have it.
Is there a source for 6829 MMUs? I would love to build a 6809 SBC with
an MMU that could run OS-9.
