Thanks for posting this fractallyte! We're separated by an ocean, so I'm glad I can see this digitised.

To answer you dang (first, I don't consider myself that), I work as a consultant currently writing C#/.NET code for a large corporation. But hopefully one of my side projects (using various other technology stacks) will pan out one day, and I'll be able to escape, like many of us here dream about (and many have already achieved) :)

I haven't been active here, but have an account so I thought I'd chime in (being "the brother"!)...

That was great fun back then and I was (and still am) a total geek. I called the various programs "routines" back then, as they were commonly known.

There was a "plot routine" which would plot points in monochrome or colour, either on screen or on the virtual screen (i.e. the 32Kb of memory that included and went "past" the screen in RAM). The plot routine used fixed point math, which I coded in a separate portion, so was as precise as I wanted it to be. I forgot what that precision was now, but it was something like 4 or 8 bytes.

Then there was the "print routine" which took that memory and output it to the printer.

Finally, the main Mandelbrot/Julia routines were done using a direct translation of the A K Dewdney articles.

All the assembler code was written in a notebook and debugged by hand before even entering it, which was done in the Zeus Assembler. Would be cool if we could locate the notebooks. At least we have the 6510 source code.
