Re: Spectranet Game docs/SDK
I was looking more into Spectranet, and want to help add support for it to Chaos and GravityPower+2 - i have some half-baked ideas for how i'd go about that, but can't find much via search and wondered if there are docs/plans already written up somewhere? Spectranet provides a bsd style socket inte...

Re: zx spectrum +2 video (composite)
You must have a load connected when measuring as it forms part of the circuit. It's also a video signal so the only way to sensibly measure it is with an oscilloscope.
The video should be on the order of a volt between the sync tips and peak white but there's probably a large DC offset.

Is it really predictable when it's governed by the random number generator?
(Yes, yes it is, especially with the random number generator Gollop wrote )

Re: RetroTINK recreates the beauty of CRT displays for serious and seriously deep-pocketed retrogamers
Don't get me wrong, I think trying to emulate shadow masks and suchlike is a worthy endeavour so that people can see the software the way it was expected to look rather than painfully pure colours and infinite-bandwidth pixel edges. I just think great big scanlines look dumb

Re: RetroTINK recreates the beauty of CRT displays for serious and seriously deep-pocketed retrogamers
To me "scanlines" is about as irritating as all those supposed VHS filters people slap on videos. You know the ones, where the picture's tearing side to side all the time and everything looks like an old 3D movie without the cardboard glasses.

Re: Noisy audio on +2, but only when RGB is connected
There's no need for a voltage regulator, one 12V pin goes to aspect switching, and the other just needs the right resistance to give the correct blanking voltage, e.g. 560Ω

Re: Noisy audio on +2, but only when RGB is connected
The only relatively cheap source I can think of, is to chop up a VGA cable… I have done this to make SCART cables for my Spectrum +3, and BBC micro. I wouldn't really recommend it as the cores are fantastically thin and horrendous to strip and solder. If I was doing it over (which I might if any of...

Re: Spectrum 128K +2 Fault Conformation?
You can find the schematic for the tape board in the +2 service manual https://spectrumforeveryone.com/wp-cont ... Manual.pdf
The short would be something after the inductor, possibly C323 if it's not a short in the motor or switch wiring.

Re: Spectrum 128K +2 Fault Conformation?
It's not a resistor, but an inductor. The value according to the schematic is 82μH. For it to have burnt up something else in the circuit is presumably shorted out. Do you mean that when you plug the tape board in it kills the machine? That would be consistent with it having a short on the 5 volt ra...

I seem to remember reading that @Guesser frowned on using such things, but I've never had any issues (touch wood!).

Why guess if there is a specification.
