Re: 7Eh near end of REM
Why would you edit machinecode? You should always place new versions of your code over the line, but better code outside the ZX81 and built a .P from that. In this way you can use much more of the RAM, like printerbuffer, sysvar and no loss of bytes for line nimbers and lengt or start of machinecode.

Re: RAM speed issue

Re: RAM speed issue
I made a simple testprogram out of a game.
After NEWLINE you will see 16 hires lines (well more, but also lines with zero)
First line 1 and 1
spaceline
Second 2 and 2
spaceline
Third 4 and 4
etc....
So you can see which bit are set by your computer.
