Re: ROM adventures (dev7rom)

Hello :)

I have a few questions.

1. In documentation, RTI (Return from interrupt) is a sequence of asm codes. Latest is LUP.
What is the parameter for LUP? Any?

2, In the same documentations wrote, a LUP changes vAC. Then for what vAC is saved if interrupt came?

Sudoku solver [prog]

Hello :) This time something different. I did sudoku solver. If you have a problem with sudoku, use this program :-) I used "brute force" and recursion method. But is fast (as a Gigatron). Time of solving may be different for different combination of digits. Usage: Coursors - move the cour...

Hello This time very easy Siepinski Trinagle generator. I used no recursion method. Very strange method, based on random numbers.
