Re: A Gaggle of ZX81's for sale

Nice to know they went to a good home! Even better if you decide to redistribute if you have too many :)

Re: New release of EightyOne available

Porting would be a waste of someone's time as EO runs very well in Wine under Linux. I'd imagine it runs equally well using Wine for MacOSX?

Re: Document Swedish Library...ZX81/Floppy

Now, how are you getting that from Sweden all the way to Texas?
Hope you get it, and share with us. If you need help, let me know as I live in Sweden.

Re: 3-lace

A tip for viewing interlaced pictures, both standard and 3-lace: lower the contrast and brightness and the flickering will be reduced A LOT.

Re: 3-lace

I was secretly hoping I could use this for my next game and not bother developing my own hi-res code. If the 'none' mode was that, then it could save me a lot of bother. However, you say this isn't usable for games, so I'll keep looking for code examples and reading up on how it works so I can do i...

Re: 3-lace

Thanks for the source code. I've been able to compile it with Flat Assembler. As you predicted, it does not work with an emulator. So I take it the 'none' mode is just straight pseudo hi-res? Yes, the source is made in ZX-IDE (flat assembler), sorry I forgot to mention that. What do you mean by 'no...

3-lace

I happened to read a description of interlaced video (again) when it dawned on me that interlacing is simply an analog function of the TV synchronisation hardware. The way interlacing works is by delaying the start of VSYNC for half a line period, every other frame. The delay shifts the start of the...

Re: ZX81CRSS.ASM

Very nice way to save some bytes in 1k-mode, which is truly needed.
