ZX Spectrum Mandelbrot

Despite the title, this version of the Mandelbrot set is monochromatic.
I was looking for something to mess with floating-point operations—something to showcase the ZX Spectrum—and I’ve always liked the Mandelbrot set: this combination of ideas isn’t exactly ideal for the Spectrum, but the journey was worth more than the destination, and if you have patience (or an emulator set to x10000), you might even have some fun.

But what is it?
The Mandelbrot set consists of those complex numbers that, when the recursive function Zn=Zn-1^2+c is applied to them, do not diverge to infinity. When interpreted as Cartesian coordinates, these numbers create beautiful fractal images!

Needless to say, this program also runs on the Spectrums repaired by Sfardo!

If you'd like, you can download this program here.

TED Game of Life

The Game of Life is also available for the TED family computer, The conversion from the C128 is almost straightforward, so why not?
I just scaled down the preconfigured examples so it would run on the Commodore 16 as well as the Plus/4.

With its included pre-built examples and a simple yet effective editor, it's a fun and educational program.
You can download it here, I hope you enjoy it.

In case you're wondering, the answer is yes—this program, too, has been tested on real C16 and Plus/4 computers by the legendary Sfardo! 

Dry Run Brusaretro 2026

Testing the setup for the Brusaretro exhibition, which will take place on Sunday, November 8, in Brusaporto, in the province of Bergamo, Italy. I can't wait!

All the hardware is provided by Sfardo, we will run only software developed by me.

We are the Hobbra Software, if you missed it. 

Gameplay

 

A glimpse of the gamplay.

It will be a game with the primary focus on 2 player and paddle controls.
However, there will also be a single-player mode and support for joysticks and keyboards.

I would like to emphasise that I do not use any kind of AI when developing my programmes; everything is  hand made.

 

Commodore 64 new game

 

A new game for the C64! It will be an old-school multiplayer game.
You’ll be able to try out a playable version at Brusaretro, a wonderful retro computing event taking place in Brusaporto in the province of Bergamo (Italy).
The game will run on a real C64 provided by Sfardo.

The Game of Life

 

Just another Conway Game of Life, this time for the C128.

It's pretty simple, with a very basic editor and a few predefined templates. I'm having a lot of fun with it, and I hope you will too.
Of course, it also works on the real C128, tested by Sfardo.

Bill Herd - Back Into The Storm

 

If you haven't read it yet, I highly recommend checking out this gem, written personally by Bill Herd.

He recounts his time working at Commodore and the creation of that magnificent machine, the Commodore 128. 

In my opinion, his creation, the C128, is the best 8-bit computer ever made.
It was also the computer I used and loved the most back in the day. 

(Thanks  Sfardo, as always)
