I am wondering how far you can go with it though especially as you can't really use page 7 which is needed for disk access and page 3 at the same time (where the bootstrap is stored in memory).

A fair few of his videos are multi-platform comparisons, but he does do the occasional standalone review now and again. Also Villordsutch, who mainly does a mix of ZX81 and Spectrum re...

Re: Finding LSB in a register

Seems to almost do what it needs to. The only thing left that I should've mentioned before is that it needs to RESet the LSB in HL (the data register).

ld c,a

ld bc,hl isn't a valid z80 instruction
