The Sinclair QL Forum

They are here. The QL shown is broken, so it couldn't say anything.

Thanks but I wanted not to use any Basic expansion. So I had to find another way. My project is to convert an Amstrad CPC Basic program to other platforms. The last results are here .
I have to confess that the QL conversion has so far been the most difficult task because of peculiarities of the FOR ...

Is there a way to get the color of a pixel at a given location in Basic? It seems I have to use some PEEKs for this, right? I hope somebody solved this problem long ago. However I can't still find any trace of this solution. So I am seeking for some help here. A lot of thanks in advance.

I just ran your programs under QDOS, and they are very impressive indeed...

However, under SMSQ/E, they lock up the QL (and of course QPC2) !

An SMSQ/E version would please many users, but the machine code would need modifying....

Accidentally, I have found out what makes my code ...

I wonder how it compares with my own Quick Mandelbrot III - http://www.dilwyn.me.uk/graphics/Quick_Mandelbrot_III.zip
This is a very good program which has much more features than mine. However it is very difficult to compare the performance of both programs.
My program uses a fixed set of ...

I downloaded the Quick Mandelbrot III, but found I could not unzip the downloaded file in QPC2, SMSQmulator or Q-emulator.

I have just put all files in folder MDV1 and added two ...

No, It is just a constant that helps to convert two ASCII values into a byte, The formula is (x1-65)*16+x2-65 = 16*x1+x2-1105. ;)
Sorry, I know very little about SMSQ/E so it may take a while for me to make a variant for it. I ...

I downloaded the file, but in the 'mandel' program, the procedure 'mandl' (see line 310) is missing... so there is no screen output...

Sorry to know this. I just put both files on the mdv1 virtual drive using sQLux or QemuLator. You need to run BOOT (you may rename this file), this asks about the ...

I had a look at your source code, it look very good.
Thank you very much. But it seems you flatter me. I am rather lazy to do all comments and other code chores.

Is there any chance of making the programme work on higher resolution QL systems, which might mean the screen is not located at 2000 ...

I have finally finished my first gfx program for the QL. It is the Superfast Mandelbrot Generator. It is available in two variants: 128x256 and 256x256.
