The Sinclair QL Forum

OK, I did it the old fashioned way... Took the EPROM out off the QSound board, inserted it to a QEPIII, downloaded the contents to a MDV cartridge (one that still works...), then switched off the QL, connected a Sandy Q-Board and floppy drive, copied the file from MDV to a floppy disk, then took the...

I have purchased the QSound/QPrint interface. I will be happy to assist. Ah that is great! I am so happy you read this and answered. QSound seems to be very rare. can you read the ROM content and mail it to me? I will try to find out most of the connections from your photo. May I ask you for contin...

This was the first Byte I bought back in the 80s. It was like discrovering I new world...

Any chance to share the article from BYTE magazine, I hope I did not put you off by my posts?

Many thanks

Certainly not Tomas - I just saw the messages.

I will scan the original article from BYTE and send a link. It contains the DATA lines for other shapes. I think the parameters of the code can be adjusted for a higher resolution QL compatible to produce more impressive images. The article also explains how to convert any shape to appropriate value...

Adjusting lines 110 to 160 as follows will produce the Sierpinski triangle:

110 DIM A(3),B(3),C(3),D(3),E(3),F(3),P(3)
120 DATA 3
130 DATA .5,0,0,.5,0,0,.33
140 DATA .5,0,0,.5,1,0,.33
150 DATA .5,0,0,.5,.5,.5,.34

an example is shown here:

The following code has been adapted for a standard QL. The original program appeared in an article by Michael Barnsley and Alan Sloan in Byte Magazine, back in January 1988. It can generate a number of different fractal shapes, including a fern and Sierpinski triangle. Lines 120 to 160 control the s...

Hello everyone,

I am new to the forum. I have my original QL since 1986.
