Sinclair ZX80 / ZX81 / Z88 Forums

I took off 1 table and now memory will be enough to code the game.

At this moment I only need to add the AI of the computer

The comments say that I can use #4000 to #400B for variables, but the org starts at #4009. Would I start it at #4000 if I wanted to make use of that RAM? Would I leave the rest of this snippet alone for my own game? I assume I could at least use the two bytes with the mem label after initialization...

What I was afraid for just happened....

OUT OF MEMORY in 1K.

I am working on solving it but it might end in cutting of a table so @dmitrii, last one added, might lose the table.

I had hoped to have a small loader that would allow loading more data in a 1K machine. Now bound on around 949 bytes.
Alas, this routine is way too large to have use in 1K. My optimized model is more effective on a 1K model.

This is an interesting thread. Is a long time that I was thinking that in order to fully (at least to the maximum extent) utilize the 1K memory it would be good to have a extremely small piece of code that (also reusing the standard load routines) could load programs. It means that first you would ...

S for Sweden would do (because i've grown up in Stockholm, Lidingö, and my ZX...

The short answer: RTFM The polite answer: ATTR(Y,X) returns the setting of the colours on that field. So when your last printed character there is a different INK or PAPER then you will get that in return with something like LET A=ATTR(Y,X) SCREEN$(Y,X) can return the printed character there but onl...
