The basic trick to multicolour rendering on the Spectrum is changing the attributes between scanlines. Then, the next time the ULA reads them for the following line, you'll get different colours. Because it's so timing critical, it's really hard to get it working inside an action game where code wil...

I first got a ZX81 because they were cheap and nobody really knew what a home computer was back then. It was always going to be a limited machine, but it was an incredible bit of design to build a computer from just four chips at the time. I liked it so much that I persuaded my parents to get a Spec...

If you want some evidence that the Atari 8-bit scene is very much alive and kicking, have a look at this Spectrum emulator that was recently written for the machine:

I think that's worth a few brown pictures, eh? :)

Revs is worth a mention too. The best racing simulator around until Geoff Crammond did it again with Formula 1 Grand Prix on the 16-bits. OK, there was a port to the C64, but that's like playing the game at half-speed compared to the BBC version. I'd guess that where the BBC loses out is that it did...

so the video chip does not steal extra cycles when it comes to more colors? a z80 at 3.3 MHz doesnt sound much faster than a 6510 at 1mhz. :P Especially when you lack charmode for moving level data fast. No. The only cycles stolen on the CPC are so that instruction timings are bumped up to the near...

No. Whatever gave you that idea?

The CPC has far more CPU power in all graphics modes than the C64, that's for sure.

oh missed this one amongst the lines, okay now show us what pictures can you do with your machines :lol: Here are some CPC ones I had lying around: http://stuweb.cms.gre.ac.uk/~bm10/CPC/oeil.gif http://stuweb.cms.gre.ac.uk/~bm10/CPC/landscape.gif http://stuweb.cms.gre.ac.uk/~bm10/CPC/almaden.gif

What is the deal with the CPC and scrolling? I've heard about it having some kind of smooth scroll capability, but just about every CPC game I've seen has jerky scrolling. Did it have some kind of hardware scroll feature that most programmer's didn't use or didn't know about? It supported a quick a...

@Oswald Dare I say it but they're a bit, erm... brown. :lol: If you want to get technical, both the BBC Micro and the Amstrad CPC were capable of much higher resolutions than you could get out of the C64: Up to 640x200/256 pixels in standard graphics modes and even more with overscan. They can also ...

About 17 million C64s were sold. This is about the only hard number we've got though as it came from the report after the company was wound up. All other figures are pretty much anecdotal. The Spectrum sold about 7 million, plus there were around a million partially compatible Timex TC/TS2068 machin...

Ah, now that's what i used to run CP/M on - not the Z80. Actually, I can't remember what I did with the Z80, expect learn Z80 machine code. Another mystery solved :D If you had an 80186 you were probably running DOS+ on it. There might have also been a version of CP/M for it, but I never saw it. Th...

I remember a lab at the university of Cambridge that was packed full of BBC Micros with 32016 second processors. They were pretty useless at the time though as there wasn't much software for them. Rumour has it that the 6502 second processor was higher performance than them too, despite being only a...

You've not played Elite properly until you've played the BBC Tube (2nd 6502 processor) version.

Here's a video of the game in action:

@Darran I think the difference is that when you get up in the morning you don't know what's going to happen for the rest of the day, whereas with a poll like this, you pretty much know the result from the off. The Spectrum vs C64 question is basically just down to who can raise the biggest flashmob....
