  1. A little bit of progress today ... Keyboard handling is now mostly sorted. Next job is probably to look at the additional 0xE0nn addresses that the #MZ80A uses for various things, including reverse video and screen / VRAM scrolling.

  2. Just looking at how straightforward it would be to extend the Pico MZ-80K to emulate the MZ-80A as well.

    Shouldn't be too difficult, and it could potentially run CP/M.

    I've a feeling I'm just about to fall down a rabbit hole that I swore I wouldn't ...

  3. Pleasingly the #PicoMZ80K also works with the #RC2014 pico based VGA terminal with the addition of an external micro sd card reader and speaker. As I've used the ground on the expansion header for the sd card, I've borrowed a ground from the unused tx/rx pins for the speaker :)

    Will be in my repo later once I've tidied the code up ...

  8. Taking a break away from the Pico MZ-80K emulator over December seems to have done wonders for my debugging brain. I think I've finally managed to properly sort the keyboard handling so that the F9 kludge is no longer necessary! Testing so far is encouraging ...
