This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

A DFI production. Released 23/10/96. But written ages ago...
-------------------------
This is the second release of dfi. A wobbly textured flag type thing.
Tripple sine wave distortion with depth cueing are used to make it more
interesting.
Yet again it was all written in assembler and squeezed with Acorn's squeeze
utility for decompression on StrongARM machines. This demo was actually
written about 6 months ago for a laugh but never released as we couldn't
think what to do with it. See if you can come up with some uses. I find it
boring after one cycle.
Full source code would normally be available for exchange - but I accidently
deleted it.
Creation credits...
-------------------
- Graphics / coding : PT
Future productions...
---------------------
The 'WhiteRoom' mega demo is still under construction. Expected time of
arrival should be 10/96. Ha ha. Maybe 10/97? Here's some more info though:
Split into 8+ sections, this demo has a story, lots of 3D graphics and more.
Work is progessing well (cough cough) and some interesting items are:
.: Realistic weather simulations.
.: Environment mapped vector objects.
.: Bump mapped textured objects.
.: Fractal textures.
.: A cow.
.: Psuedo realtime raytracing (eh?).
As PR Wheatlee would say 'presentation is to the fore'.
We're currently busy working on the 3D graphics engine and various utilities
to aid the creation of both code and graphics. Keep your eyes pealed for
future releases of these.
Who?
----
Expect to hear a lot more from us in the near/distant future. In the mean
time, we're always happy/desperate for new contacts so please mail us at:
