Draw a Sierpinski Triangle using a Chaos Game method.

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.

So the kids and I had a bit of a play with some graph paper and felt pens last night. We are going to write a Bruce Lee Vs Ninja's platform game using Trickys BASIC sprite routines.IMG_20201009_094253.jpg I use Excel's Conditional Formatting function to design sprites. BBC BASIC code can even be wr...

Hi Joe,


I have an A3010, and am looking to replace the bottom half of the white plastic case as one of the four plastic protrusions that the keyboard sits on has broken off. As you are breaking the A3020 for spares, would you be interested in selling the bottom half of the case to me?

I have a tiled background and a second layer of sprites - players and a cursof- over it. I want to move the layer 2 objects especially the cursor without havinv to redraw the whole tiled map which really slows the cursor down. What is the best option to remove the layer 2 sprite 'smudge'? Rather th...

Is there a document that explains how many Sideways RAM slots there are? How do you load a ROM to them , what the addresses are? Basically everything you need to know to get ROMS to load in your Master Cheers! I like the book 'Advanced Sideways Ram User Guide' by Bruce Smith. https://www.brucesmith...

The Rocketman sprite in the first Planet Nubium game was drawn using the XOR method. Here the background undergoes a bitwise XOR with the sprite. The method is quite simple and the same bitwise XOR routine is used to remove the sprite. However, with this method when Rocketman crosses over a coloured...

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 ...

- There are lot af games, but finally "few" classic games coming from C64/Spectrum/CPC on this computer. Why ? Because it was consider as an educational computer ? (like Thomson computer in France). The BBC Micro had many great conversions from the 8-bit arcade games, but as software hous...

The Wikipedia article (below) on the Rugg/Feldman benchmarks (used by PCW magazine back in the day) found that BBC BASIC was the fastest of the 8-bit BASICs. The reference does not give a figure for Locomotive BASIC and I guess this figure for BBC BASIC is for BASIC2 rather than BASIC4. It would be ...

I found the book 'Advanced Sideways Ram User Guide' by Bruce Smith useful when writing Planet Nubium and PN2. Both games use all four SWRAM Banks of the BBC MASTER, some lines of BASIC in the main game loop, and both main and shadow video RAM for two separate video frame stores to double buffer the ...

I thoroughly enjoyed Andy Remic's superb movies on the ZX Spectrum.

My games for the BBC Master, Planet Nubium and Nubium 2, keep the guardian sprite bitmaps and blitting code in SWRAM Bank 7, with the location in screen memory of each sprite in a parameter block in main memory, just below screen memory. To draw the sprite in PN1 a CALL is made from the BASIC part o...

I have never played Planet Nubium (spending too much time in my Acorn Electron bubble :mrgreen:) but I just gave PN2 a go in jsbeeb. Very cool game, well done!! =D> =D> =D> Thank you. My childhood machine was an Electron, so it is great to see your demos pushing the Elk to its limits.

pure brilliant =D> =D> =D> How did you design your loader? Nice. Thank you, AJW. The loading picture is based on clip-art from the Internet, modified, colourised and resized with Microsoft Paint. I imported the image into the BBC Micro using the 'BBC Micro Image Converter'. The loading tune runs of...

This thread (below) maybe of interest.

I have not yet figured out how to make an interrupt timed palette switch work for both interlaced and non-interlaced displays though.

I have run Jonathan Harston's BBC Basic for the C64 on the VICE emulator, and very good it is too.

Jon also has a port to the Spectrum.
