B/FEA1

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.

Another look through the back issues of "Electron User" magazine.

ARTICLES
~~~~~~~~
Intoduction to programming (Part Five) - by Pete Bibby. The list of BASIC
commands already explained was growing. This time the ins and outs of
"INPUT" were discussed.

Graphics - by Mike Macmanus. Delved deeper into the use of VDU19 to
enliven screen displays.

Program Probe - by Nigel Peters. Explained how multi-coloured User Defined
Characters could be constructed by using VDU5 to join the text and
graphics cursors together creating an overlay effect.

Maths Workout - by Mike Bibby. The wonders of Bits, Bytes, Nibbles and
Hexadecimal numbers were revealed.

LISTINGS
~~~~~~~~
Random Coloured Lines - by A. Farmer. It's strange to think that ten years
ago we were all enthralled by programs like this that had almost no merit
whatsoever!

Screen Set-up - by A. Oldham. This prog took 34 lines to set the
background and foreground colours of the screen display when two simple
VDU19 statements could have done the same job.

Code Breaker - by Roland Waddilove. Long before he became Elecron User's
editor, Rolly baby was sending in well written little progs like this
which was a computer version of the "Mastermind" coloured peg logic game.

Laser Shootout - by Marcus Adams (I think!). This shoot-a-moving-target
game appeared as an accompaniment to a review of the Signpoint Joyport - a
joystick interface designed to fit straight onto the Electron's expansion
bus, which wasn't much use if you wanted to add a PLUS-1 at a later date!
If you didn't have a Joyport you could use the keyboard instead.

Sounds Exciting - You were invited to pin back your lugholes and sample:-
Piano Scale, Wasp, High Dive, Singing Alien, Crash landing, Boing, Foghorn
and the rather pretentiouly titled "Music of the Spheres"!

Fun with Circles - by M. Philips & A. Golden. A short, well structured
program that used (pinchable) procedures to draw filled circles and
semi-circles. The resulting picture was of that smiley face that first
appeared in the early 70's and was later hijacked by Acid-House music
freaks in the late 80's.

Casting Agency - Modes of transport seemed to be the theme this month. The
bit patterns were for:- Bomber, Oil Tanker (ship), Motor Bike, Car, Plane,
Racing Car. Vrooom Vrooom!

Money Maze - by Roland Waddilove. Rol(or "R" as his friends called him),
presented his second offering which was a PacMan clone. 

V.A.T. - by Simon James. A short prog to calculate the Value Added Tax for
a given item.

Crystals - by David Davies. Graphics demo that used palette changing to
create the illusion of rotating crystals.
