That looks great. Bookmarked to have a closer look. I cut my teeth on a Model 1 Level 2 in 1979 and have been coding ever since. Still have my original working one, a spare and a model III in the attic. Probably a decade since I switched them on though :-(

The manuals were excellent and even showed a short machine code program to white the whole screen. Having used the "poke" statement in basic to do the same thing (which took around 2 minutes), I was blown away that machine code was almost instant. I taught myself assembler with the Zaks Z80 book

Did lots of hacks to the hardware, lower/case, speech synthesiser, motor control, added a parallel EPROM to hack the ROM code. So many memories.
