Nice job. I only had a glance at the code, and spotted one instruction that seems unnecessary (the ASL three lines after NOTNEG), but that's a bit of a silly optimisation - there are probably more significant ones elsewhere!
Thanks!

Here's that ASL instruction in context:

I put together some 6502 code to output the exact decimal ...
