Manic Miner Level Select/Skip

At one point in time I did have an .ssd of this game with a level select or skip, I cannot recall exactly which as it was a long time ago now I think, it was either: 1. Watch the demo then press a key to start the game on that level being shown (this seems quite likely) or 2. Press alpha key to pick...

Re: Acorn teletext adapter

Although slightly off topic, I had one of these not that long ago, maybe about two years back. I did sell it along with a few other items I did not require at the time, although I did have a very vague idea of selling its internals and keeping the 'cheese-wedge' case for other projects but decided n...

Re: Any short type-ins for unattended Beebs?

Thank you! I like AndyF's idea of making an animated Technician Ted. Does anyone know of a sprite sheet for the Spectrum version of the game? Technician Ted seems to cycle through more than 4 frames when he walks. In the TechTed game he has 8 per direction ( ! ) however I used his sprite in a few J...
