Re: Fastest way to do a little BEEP
Fine, @utz, it's like mine but with less bytes, congrats. But there's something odd... these routines make beeps not like ROM ones, but like the intro of Skool Daze: https://www.youtube.com/watch?v=ULCjgUNz6bQ I thought ROM beep would be the easiest way to do a beep, but I think there must be somet...

Re: The ZX Dev is back... ZX Dev Media - Demakes!
I don't know if the judges gave any extra feedback, besides the point by evaluation category.
But it would be nice to have some textual feedback on the games.
These things take months to do, ... some even years.
So a more in depth feedback would be nice.

Re: Website DNS is flaky at best
Unless someone else replies I would have to assume that it may be a small concern at your side. Its quite fast to load here. It's unrelated with sped or load. It simply doesn't resolve the server name. Perhaps you can if you wish do a flushdns on your machine or reboot your router maybe if it persi...

Website Issues
I have been having issues accessing the website, because the cloudfare DNS servers (registered for it: arvind.ns.cloudflare.com, daniella.ns.cloudflare.com), are not resolving the spectrumcomputing.co.uk domain name.

Re: Building an analog paddle converter
I'd suggest replicating the input ports of a Kempston mouse; use the X and Y addresses for two paddles (numbers 0-255 read with an IN) and combine the two buttons onto the third address. My own thoughts for paddles was to wire a couple of spinner encoders up to the XA/XB and YA/YB inputs of a real ...

Re: Reaction
Not too hard for sure. First run I did and I got 2 averages under 0.40 (Magenta 0.39 and White 0.38). Averaging 400 ms per reaction, it means, 20 PAL frames (20 ms each), which is a lot. If doing it a second time, I'm sure improvements would surface, since this first run was to understand how it wor...

Re: Keyboard and Kempston at the same time.
Yes. The keyboard, Sinclair, cursor and Fuller protocols are active low, but Kempston is active high. It was a bad hardware design decision that’s way too late to correct. ... I wonder why you consider it to be a bad hardware design decision ? If it was active when zero, like the keyboard: - There ...

Ast A. Moore, if no kempston is attached, then is the read value 0x00 or 0xFF? On some devices random byte is read if there is no kempston. ... Any ZX will read "garbage", if the reading is done just after the ULA read the pixel and attribute data to render the display. This is what is kn...
