Yes, and don't forget that the lower 16k of spectrum memory has an access speed restriction, too.... > I considered moving into Z80, since my 8 bit background concentrates on 6502 > coding, which is far simpler (For Constant speeds and variety of > instructions) but i am rather heavily put off by the speed restrictions > noted! > Like you, my first experience in machine code was 6502 on a Commodore 16, and I found the z80 to be quite weird at first.... lots of odd instructions I thought I'd never need, no zero page, and bizarre 16-bit registers. But I'm glad I did bother learning - the z80 is a lot easier to build hardware for than the 6502, and you can pick up z80s for about a quid. I don't think the speed restrictions are that serious - the excellent games on Sam (eg Prince of Persia) are proof. And you could always turn the screen off to get full speed. Andy
