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.

StarBase Attack
***************
This is a version of the BBC and coin-op classic.
It will run on A3000's etc... but also features the option
to run using the Risc PC's additional graphics power.
To the unititiated few, the aim of this game is to prevent the nuclear
destruction of your cities by destroying missiles as they descend to earth.
Simply point and blast. You get 150 points for each city surviving each wave
of missiles, and 10 points per round of ammunition.
You have finite ammo so don't go too wild.
If you want ultra difficulty on the Risc PC, type this at the command line:
* RMFaster Basic
N.B. This is definitely NEEDED for the A3000's etc.
(This loads the BASIC module into RAM and makes the game run 30% faster... )
(... Due to faster access time... )
(... which RAM offers.)
There are 4 types of missile fired at your cities:
1 - Normal
These simply descend to earth in a straight line.
2 - MIRV
This type of missile looks like a normal missile but will spontaneously
erupt into 3-10 different normal missiles.
3 - Shifter
These missiles also look like normal missiles except that occasionaly
they will shift direction and speed.
4 - Smart Bomb
This missile appears red on the screen. It can 'see' your anti-missile
devices and if it detects one beneath itself, it will move up out of the
way and continue its descent. The only way to destroy these weapons is from
the side or above.
