BTW: do you use the optimized base where the call to MC is fully placed over sysvar and so saving most bytes?
You bet I did. I just totally copied the code you'd put into the 1K Jewel game and used that. So this program does not ever use the Basic system.

Re: 1K Sudoku Solver

@ Moggy I found the problem. The zero to indicate stop went missing in the change over to the new compiler from the other compiler I had written it on. If I input your clue numbers and hit solve, it goes around and around until it stops with no solution found. I tried your clues with an on line solv...

Re: 1K Sudoku Solver

@Bukster. Tried the following grid (see picture) on both emulator and real 81. It never seems to get beyond the third line, going into an endless loop as it were. Have run it on emulator speeded up X100 and still no solution after 2hrs run. Just a heads up nothing more as I still think it's great f...

1K Bejewelled style game

Here's a 1K game I wrote I call Chain Reaction. It's basically a bejewelled game where you swap two numbers to make a line and try to start a chain reaction. You get 1 point for every number removed, then 2,3,4 up to 7 times for a chain reaction. The controls are: Any key to start (gives the randomi...

Re: Hello from North-East England!

Early computers are still worth studying. Modern computers may seem different, but the underlying technology is essentially unchanged. A lot of people using computers today have no deep understanding of how they actually work. You can learn a lot here.

Re: ZX81-IDE Software Development Tool, IDE

I've been doing some ZX81 work with Flat Assembler and am working on a 1K game. However with 1K every byte counts and I haven't seen any examples or documentation where I can make the program go straight to the USR routines without ever using ZX81 basic. So under Autorun I have to have the command R...

Re: Berzerk in Hi Res

After some suggestions and bug fixes here is the final version of Hi-Res Berzxerk. This features robot movement and a number of bug fixes. Only two robots move at a time to keep the game play fast and keep the challenge up. If they all move, it's more like robotron. Shoot one moving robot and anothe...

Re: Berzerk in Hi Res

I've had a few requests to make the robots move. Here is an updated version with robot movement. Only two robots at a time move. I had to cut back a few game frills to fit this in. There is still the mini game on the title screen. I didn't want to lose that.
