Re: Resizing the screen (number of lines)

I found a work-around to what I wanted to do which meant not POKEing anything :-)

See my new Fruit Machine thread in this sub-forum.

Re: Resizing the screen (number of lines)

Thanks for the link, but there was also a way to do this in BASIC on an unexpanded ZX81 - unless my memory really is failing me.

Resizing the screen (number of lines)

can it be used for graphics?
In what way? DEF FN can be used for any calculations, so yes. You may also be able to use the USR command with it as well to call let's say certain ROM or MC routines directly.

Re: ZX81 Clone Tynemouth Minstrel 3

Just a thought, does the Chroma Interface work with the Minstrel 3 clone? If so, is the Chroma still available to purchase?

Thanks,

Shaun.
