Thanks for your work on this (I was the guy who wrote the original Wiki
article, but no access to a TPDD1, so it was all conjecture).

Hello all,
I haven't done much with reverse engineering work the PDD1
firmware in a while, I've been too busy with work again. But I did
drop everything I have on GitHub if you want to have a look. I've
given names to the different registers, and some subroutines in the
assembly file. The Hitachi 6301 uses the same opcodes as the Motorola
6800, and is fairly easy to follow.
