Well, Paradox 2000 finished a while ago, but checking the offifial site, there's been no releases of Speccy demos (or have I missed something). So, with a little of my help, Gasman set about finding and converting some of the demos. I've not noticed an update on Demotopia, so instead I'll put up some files here:

Zool 4k Intro/FS/DHG

Whim 16k/Accept and Nature 16k/FS/DHG
So far, this is all we've converted to friendly .TAP files, although I have the music in some obscure Russian-clone-format (well, it's obscure to me <g>). If anyone wants it, I'll be happy to send it on, tho' it's probably safer to wait until it's been converted.
Enjoy.
