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.

!Projector Version 1.08 (FOR NOTES ON LATEST VERSION SEE END)
=======================
This projector is for playing Ace film format
films, produced with either:-
Euclid+Mogul (3D)
Paint+Splice (2D pixel based)
Draw+Tween (2D object based)
This is a Multidocument/Multiwindow version.
You can pop up a menu in the film window.
Most operations are obvious (try them!).
In Freeze mode you can single step the film
by using Select/Adjust on the window.
The New View option (under Misc) plays another
instance of the film, but uses the same copy in
memory, so is different from actually loading a
film twice.
Using an Obey file you can load a set of films, and
optionally set them to play immediately in a rolling
demo. The syntax is either:
[<Projector$Dir>] Film Film Film ... [-Cn] [-Fn] [-R[n]]
E.g:
Films.Humans Films.LitLogos Films.Chess -C2 -R
The -C and -F flags control the count for repeating
each film and the flyback count per frame respectively.
Or:
<Projector$Dir> -L {[-Cn -Fn] Film}...
E.g.
WimpSlot -min 800k
<Projector$Dir> -L -C1 -F8 Films.Chess -C2 -F2 Films.Flag
Note that the usual controls over each film are available.
Pressing S will skip to the next film irrespective of the
repeat count.
The -L flag forces the films to be loaded one at a time
rather than all in one go for the -R flag, and allows a
longer rolling demo from a Hard disk.
Please send examples of good films together with
permission (or not) for distribution to:
Ace Computing, 27 Victoria Road, CAMBRIDGE, CB4 3BW.
Details about Euclid, ArcLight, Mogul, Splice and
Tween can be also be obtained from the same address.
Tony Cheal Jan-Feb 1990
=======================
1.07 (Jul? 1990) The projector now intelligently
plays films in new modes which match the film's
mode in bits-per-pixel and aspect ratio.
1.08 (Aug 1990) New key - Ctrl-B in full screen
mode puts the keyboard into a mode which will
always single step the film forward one frame.
Another Ctrl-B will get it out of this mode.
Now includes a new EuclidX to play Lempel-Ziv
compressed films. Note that if a Euclid module
is already running which does not have Lempel-Ziv
decompression (i.e. prior to 2.12) then Lempel-Ziv
films will still cause errors.
