This demo has been made for ZX81 with ZXpand with AY-module. It's only BASIC, in a joke convention rather, but still - actually it shows for real coders what could be possible to do with the mentioned full hardware combo, if even such a bone-head like me could do anything bearable.

ZX81 is a Sinclair Research computer released in 1981. It has no sound, 1Kb of memory, and black&white (monochrome) graphic in hardware resolution 64x48 pixels. BASIC is its main operating system, working on Zilog Z80 CPU 3,5Mhz.

The newest device for ZX81 users is ZXpand invented and developed by SirMorris and being sold by RWAP Software. The ZXpand gives to our ZX81:
- 32Kb of RAM,
- flash (instant) loading/saving of programs,
- SD card as an easy data-transfer with PC,
- sound of AY chip (nowadays it's mostly Yamaha YM2149, like in Atari ST and a lot of ZX Spectrum machines),
- joystick port (in the AY module),
- the port mentioned above is also a port for mouse (also in standard of Atari ST).

The song from this demo is called "Rubber pleasures" and You can download its MP3 recording from here: http://yerzmyey.i-demo.pl/Yerzmyey-Rubber_pleasures.mp3

Also I invite You guyz to ZX81 forum:
It's quite strange to hear such song from a ZX81(a "no sound" computer by design).
The chiptune is nice and the 1k twister make me smile ;)

Made me smile, also this must the ultimate niche platform to make a demo for.

Unless someone made a colour graphics card for the ZX81? There was a rumour back in the day?

Why do you keep insisting that the ZX81 cannot produce sound, because it most certainly can.

Cool demo!

Music makes up for the basic effects; but alltogether very enjoyable. Loved gasmans twister :).
