LED Matrix with homebrew gaming computer

This is the first demo run on my homebrew gaming computer. It has been a long road (one man and five months of spare time, still needs input/output device capabilities and some hardware debugging). The system is housed behind a custom built LED dot-matrix display featuring 18-bit colour and a 64x48 pixel resolution.

The demo was written for Hacknight II ( http://hacknight.se & http://forskningsavd.se ).

The microprocessor is the Zilog eZ80F91, a descendant of the famous Z80.
The sound- and graphics-hardware is custom VHDL on the Altera EP2C8.
The system consumes up to ~14A at 5V when displaying an all white screen (it is very bright, it's midday summer outside).

The soundcard is Amiga 500 compatible and plays ProTracker mods without conversion. Audio has been added after the video was recorded due to the bad quality of the recorded audio, but it is a true recording from the sound card. See http://www.soundcloud.com/stg-1/ for more audio demonstrations.

This project is published as open hardware, open source and all schematics, pcb designs and half blog/half wiki on the construction is available at http://forskningsavd.se/wiki/index.php/Rbox_game . I have not yet had the time to publish the code publicly, but it is freely available upon request. The same goes for all original schematic and pcb designs, should anyone be interested.

Mine is called Enigma.mod

If I'm not mistaken it is the theme from the Enigma demo on the Amiga :)

[SenseiTG]

Thanks dude(tte)s :)

[keoni29]

Music sounds like Christopher Hüelsback composed it!

[ZXRulezzz]

@SenseiTG Well, my mistake, that's actually Enigma. They both sound very similar in the beginning :)

And they both were in Amiga (Enigma.mod also had Atari 8bit conversion) demos, Stardust.mod is from "World Of Commodore 1992" by Sanity :)

Good times... :)

Wow super thanks for share

STARDUST.MOD :D

Simply awesome!

How did you learn all of this!

PLEASE IM DESPRITE TO KNOW.

Im a programer so it should be quick at learning.

I shall call you MASTER from now on. Too bad I don't have time to get into using FPGAs... Well done!
