Re: USCII, the User Specified Character Integrated Interpreter

USCII is very cool.

LINE,x,y,x,y

Re: Zxpand to sell?

Re: Started learning Machine code: Am i doing this correctly?

I don’t see any sarcasm.

I would recommend the book Machine Code for beginners, that learns both Z80 and 6502 machine code for any 8-bit micro. Or Mastering Machine Code on Your ZX81 that specifically targets the ZX81.
