Re: Calvary Class - sequel to Masada Class game
If the ZX81 cannot access memory over 32k, does that mean with 8k taken by the ROM, you've only got 24k to use? Minus screen ram (lo res 792 bytes) and it's closer to 23 kb usable ram. Is that correct? If I'm using hi res the screen is around 6K, so that would be 18kb usable ram It's still a lot mor...

Re: Calvary Class - sequel to Masada Class game
Both Chroma and ZXpand provides at least 32k RAM, so it wouldn’t be bad to use that amount of memory for your great games. True, but I'm trying to write games that will run on original hardware. It's a personal rule, however if I put that to one side, there would be enough memory for powerups, more...

Re: Calvary Class - sequel to Masada Class game
A valid point. I had wanted to add powerups and more stages however, by the time I had the backbone of the game programmed there wasn't much memory left. In hindsight, perhaps I should have done it in lo res.
Still, it could make a good basis for a low res game with more stages and more features.

Calvary Class - sequel to Masada Class game
I've finally finished a Hi Res sequel to my old 1994 game Masada Class. This continues the story which left the heroic Masada damaged in space and spinning out of control after defeating the alien menace. In this game, you are the AI of the newest ship off the line - the Calvary. Travel to the alien...

Re: 1K Sudoku Solver
I'm using FASMW-ZX.EXE version 1.71.01
If there is a new version out I'd be interested in having a look at it.

Re: [TUTORIAL] How to disassemble ASM in VB81 XuR ?
It's rather ironic that I was working all this out only a couple of weekends ago to disassemble and old program for mine so I could replace the basic bits and make it 100% machine code. So only after I'd done it myself do I see this guide. Never mind, thanks for posting it.

Re: New to the ZX-81
Get an MP3 player, download some ZX81 software and see what this little machine can do. They are a lot of fun and can do more than you might expect.

Re: What does ULA stand for?
I think it's Uncommitted Logic Array. So your link was close to the mark.
