Re: Today I received.....

I received a ZX Spectrum+ in the post this morning. It'll likely need an RGB mod before it'll be of any use though. This is the second retro machine that I was literally just given (the other being an Electron). Seems once you become known as a retrocomputing freak, people just start giving you old ...

Re: Apple goes ARM

Mmm. Saw this today. I like the ARM architecture and feel a certain wistfulness towards it for obvious reasons, but I'm not convinced about performance. I suppose there are arguments to be made that most users who spend their time in a browser don't need bleeding-edge speed any more, that the Mac ha...

Re: Elite's graphics

I've never read the code and I suspect I'd be too stupid to understand it anyway, but I believe the line drawing routines are all custom. IIRC they actually had multiple redundant routines, one of which was picked for the job depending on the nature of the line to be drawn. Apparently there was some...

There was a type-in from Beebug (or was it The Micro User?) that sounds a bit like this. Will see if I can find it.
It was BEEBUG, titled Artillery Duel, and I'm pretty sure it was in Volume 1, or possibly 2.

Re: BBC sampled sound discs: smooth streaming, 50Hz oscilloscope

Very cool!

Great stuff as always. Impressive that you can get entire songs on a disc.

It's interesting that it wouldn't work at all if the chip implemented its attenuation symmetrically!

Good work. What's the best way to fix this, then? What happens if you just get rid of the SOUND altogether? Or move it outside the loop? Or just reduce the duration from 2 to 1 (or 0)?

I played this on the Beeb BITD and it was indeed ridiculously fast.

Re: Seeking ways to showcase fast second processors

The BEEBUG BBC BASIC Mandelbrot implementation was the algorithm I suggested over in the beebjit thread. Disc image here . I think it takes about 15 minutes (~900s) to draw the default Z^2 set on a Beeb, and you can watch it progress, so it should be good for three orders of magnitude improvement (9...
