Mandelbrot Set Plots

[GCHarder]

Here's a collection of Mandelbrot Set plots for those interested.

There are 15 plots, each with two versions.

MuNNNF.p (NNN=000 to 015)...

These require a 16K+8K LOW RAM WRX capable ZX81.

They were created using the program "Mand-FFP", (Mand)elbrot (F)ast (F)loating (P)oint by Fred Nachbaur, 1986.

MuNNNM.p (NNN=000 to 015)...

These require a 16K+8K LOW RAM WRX capable ZX81.

They were created using the program "Generalized Mandelbrot Prototype", MGP, also by Fred Nachbaur, 1988.

See the contained txt file for more info.

Works very nicely with the No$ZX emulator, unfortunately, this emulator
has some problems with Hi-Res displays.

Can't wait to try this on the ZXpand.

Where's the turbo-charger when you need it?

I'll watch for the lights dimming

These programs, with the exception of "Generalized Mandelbrot Prototype" could run on a 16K ZX81 with a HiRes modified RAM pack. All that would have to be changed is a pointer to the Hi-Res display file, I think.

Unless you plan on rendering plots these aren't hardware intensive programs.
