Mandelbrot or Julia fractal

Hi, I am looking for a mandelbrot fractal or julia fractal program for the Apple II.
Preferably written in 65(c)02 assembler, alternatively in Integer BASIC (using I lot of peeks and pokes, I suppose).
I have looked all over the Asimov server, but found nothing.

Any hints?

Hmmm, really? There's an Apple 3 Business BASIC implementation:
documentation/apple3/dtca3doc/DTCA3DOC-097 basic - mandelbrot set.pdf
And of course a version for the GS (GSOS/Pascal):

Another option is to take a look at Mike Willegal's Scelbi site

http://www.willegal.net/scelbi/apps8008.html

There is an assembly language Mandelbrot program for the 8008 processor.

You could adapt it to an apple II, the 8008 is way harder to program for than a 6502.

Cheers,
Corey

This magazine article was very good.

Better get that Info Quickly...

CALL-A.P.P.L.E. is reporting that Bob Bishop has recently left us.

David:
Sorry if I didn't make everything clear. Of course I have seen the GS version and the A3 mandelbrot program (which is a good thing, because what I am really trying to accomplish is a sort of benchmark test).
However, as of yesterday, I haven't found a mandelbrot program for a standard Apple II that is not written in AppleSoft or Pascal. So I will check all the links you all have provided in this thread.

Ultimately, I will find a program that is easy to convert to other 65xx platforms (Atari XL, Commodore 64/128) and that will allow me to compare
- standard Apple IIs
- GS running at 2.8 MHz
- various accelerator cards
- Apple III.

Stupid idea? Perhaps ... but I love the idea ...

Not stupid at all .... but i´d recommend to take a source from Pascal because it´s portable to all named platforms and might even be used at none Apple brands....
you might even compare the runtime also with different kinds of Z80 cards ( with different speeds ) at CPM or even at IBM clones at CPM86 !
