RE: Unused registers on 67 and 97
Nice work!

In my attempts at 67/97 firmware hacking, I haven't tried to maintain the ROM size. I've added additional bank 1 ROM. Getting more program steps by relocating the secondary and status registers is not too difficult, but expanding the available indirect registers takes more work, and I haven't yet started on card reader support for larger programs.
