Sinclair QL has a tiny demos without sound.

QL has http://www.pouet.net/prod.php?which=58498 Nyan with "sound".

I loved my QL when I was 12. I learnt a huge amount of programming on it.

In retrospect the hardware is a piece of crap!

QL-emulator and software too
xD

Speaking of Sinclair: Cambridge Z88 (there are some dev tools here)

where are no platform in list

link no work :(

"where are no platform in list"

where ? I don't follow.

@DaD1916: look at Prods->Platforms.

BeBox?

DaD1916: X68000 occurs twice in the list. FYI the NEC PC suggestions are among the "more Japanese hardware", but there are certainly others. :)

... mainly Sharp X1 and Fujitsu FM-7 (8-bit predecessors to X68000 and FM Towns, respectively).

NeXT?

@kuiash: there are some BeOS demos and even a pouet category for those. But right, not sure if any of these has PPC binaries.

A few more that I don't think have been mentioned in this thread:

Bandai Playdia
Casio Loopy
Casio PV-1000
Gamate
Hartung Game Master
Interton VC 4000
Konami Picno
Tomy Pyuuta

There is at least 1 slideshow for Tesla Ondra computer http://www.ondraspo186.8u.cz/?p=46

I am pretty sure there is no demoscene related production on Grundy NewBrain.

some prods for PMD-85 has made.

Haven't come across anything for the Canon X-07 either, unless some sound experiments count as demos.

Surely if the BeBox runs BeOS, then all these count as prods for it ?

^edit, well the three in that list that aren't some sort of port anyway :)
