Re: Silly Questions

No, you won’t. LIST will show the BASIC program as it is in memory. For example, the first two bytes you give in your example - 0, 10 - is the line number “10”. The machine code instructions are never stored anywhere, the BASIC is interpreted line by-line as the program is ran. This is completely di...

Re: Silly Questions

BASIC is interpreted on-the-fly, not compiled, so you won’t ever see the actual assembly call in the listing.

For more details look at chapter 27 in the ZX81 manual

Brilliant, thanks for the fix!
I’m so glad that a solution was found for that! 8-)

Re: Personal challenge: Writing a text adventure in 1k for the zx80

Machine code, and 16k. You can do a lot in 1k, but I don’t think an adventure would be right for it, especially as you want to include graphics.

Re: The hidden program on a blank tape...

I remember these from back in the day, I had quite a few. You’d be kinda curious about the program, but knew it wouldn’t amount to much as the type-in listings in the magazines and books of the day would be much longer to produce anything of merit.

Re: How to fully use the 1K ZX81

Yes, but 655536? Should be 65536, one too many digits.

Re: How to fully use the 1K ZX81

I’ve just started reading this. Although we both code the Zeddy for very different types of game styles I’m sure it will be interesting. I have noticed an error though on page 2, where you state that 2 bytes will be needed to store values up to 655536… There’s another further down in the Scoring sec...

Re: new game ZX81 - TERRA 81

Curious to know what happens to this project, as the kickstarter has now finished and the project wasn’t funded?

Re: new game ZX81 - TERRA 81

Hi I need hours to create the game. the necessary hours are taken away from my work. Maurizio I wish you the best of luck with this, but I don’t think Kickstarter is the way to do it, especially as you won’t see any of the money unless it is completely funded. None of my ZX81 games has made the amo...
