Still can't quite believe this! Hello everyone! My quick lockdown project has turned into a labour of love.

I'm currently working on a proper bios, bootstrap, monitor and native assembler using the tutor monitor as a starting point. Then I think the following in no particular order:

- 8 or 16 bit external data bus level shifted to 5v through the two remaining pmod ports

- keyboard and screen modes via gameduino. I've already got the amiga font working on it.

- audio output on a pwm pin

- case

- in-line assembler modification for eh-basic a la bbc basic.

- custom pcb design (once I've taught myself layout)

Anyway, thanks for following :)
