The Sinclair QL Forum

Greetings all, as my QL continues to sit in a cupboard and I find more fun to play with QPC2 and SMSQ/E, I developed an alpha version of a "missile command"-type of game under QPC2. It should adapt to various resolutions. It only uses COLOUR_QL so it can run in virtually any resolution and...

If you need/want a 32 bit by 32 bit multiply routine, then Issue 11 of the extremely random eMagazine on Assembly Programming has on which I wrote and is free for all to use.

Decided to rediscover the 68k assembly language and try to implement a mandelbrot code iteration in asm with fixed point integers. 1st go used 16bit due to the 68k 16-bit MULS/MULU limitation (16bit operands). Limited to 11 bits after decimal point. 2nd go implemented a 64bit multiplication with 32b...

170 REMark PI=4*ATAN(1) , wil avoid the name-table clash ! 370 & 530 change FOR i% to FOR ii , as QDOS does not accept integer for loops.... Thanks Steve, I couldn't remember if PI needed definition on a QL or not.. and thanks for the note on integer loops. Fill fix that and update the repo.

Hi folks, played a bit more with fractals over the weekend. If any of you has got one of those red/blue 3d glasses, you can play with the Lorenz attractor. Source is here: https://bitbucket.org/mrzap000/lorenz/src/master/ Pretty basic, not smooth, didn't have time to find some smarter way to animate...

Hi there. While moving with family to a new flat, not much time these days... thought I would put the program on a public Bitbucket repo, you can download it from there https://bitbucket.org/mrzap000/mandel/src/master/

Hi, Apart from my spelling and grammar errors, I was hoping for a comparison of SuperBASIC and SBASIC to Turbo compiled when performing Mandelbrot Set generation. Not SuperBASIC against SBASIC, it is well known that SBASIC is faster, can execute basic programmes. Whereas QDOS requires Minerva v1.90...

Hi folks, silently been on this forum for some 8 years, switched on my QL last time in 2015. Been coding since the '80s as a pastime, mostly C/C++/python on linux, all sort of useless stuff from 3d libraries for 3d games in console mode, to new languages (both interpreted and compiled). Re-discovere...

Just read that the main man has died, aged 81. That's a bummer. I hoped he would go on forever. At least the things he put to market in the 80s are still being tinkered with and will certainly live on. That dark beauty that entered my room in 1985 and is still perfectly operational despite the laye...
