Back in the day for my AO-Level computer project I used an Electron with PLUS-1 interface to both read temperatures from an analogue temperature sensor via the analogue joystick interface, and to drive relays from the printer port through an eight channel Darlington driver chip. I used the printer p...

Re: Elementum for Electron and BBC Micro/Master

Brilliant and original game.

My only suggestion is to make additional keys, such as A and S keys, move the electron left and right as well as the Z and X keys. This way, the game can be played under emulation on PCs with foreign keyboards such as the German QWERTZ keyboard.

Planet Nubium Two uses a sprite mask to display the Rocketman sprite. First, the background where the sprite is to be plotted is copied to a scratch area of memory. The screen memory then undergoes a bitwise AND with the sprite mask, then undergoes a bitwise OR with the sprite itself. The result is ...
