Re: Musical potential of the NEXT.

The exUSSR community has extensive experience in the development of sound systems for the ZX Spectrum. TurboSound and TurboSound FM systems are our developments. Experience in the development of these sound systems has shown that it makes no sense for ZX Spectrum to create an iron system that does n...

Re: Musical potential of the NEXT.

There is a contradiction with the original concept of ZX Next. Using YM8930 instead of the third AY891x would probably make sense if it was originally planned. But in the ZX Next, the first two AY were originally positioned to play TurboSound music, while the third AY was positioned as an auxiliary ...

Re: Port system documentation updated

No problem. You have the opportunity to offer a better way how to separate Kempston mouse and Kempston joystick. :)

Re: Port system documentation updated

Say, I want the value in a register other than A, especially if I want to preserve A. Once the rules are written, and embodied in the hardware, these rules should be executed, otherwise the software will not work correctly. You can break existing rules if you don't care about your reputation. You h...

Re: Port system documentation updated

Sometimes the plane crashes, but nonetheless, the aircraft continues its development. Civilization means development. The exUSSR community has 30 years of ZX Spectrum development, and we are not afraid of possible problems. The Western community is taking only the first steps in this direction. The ...

Re: Port system documentation updated

The only misunderstanding is yours. A16 adds *new* rules. How much existing software is broken by these new rules. It is you who have the abrasive opinion that not following the rules for a separate branch of development is somehow broken. In cases where it is intended to use A16, the existing soft...

Re: Musical potential of the NEXT.

Since "AY-3-891x" has the upper bit of the register fixed to "0", I think that the function can be extended. I posted such a thing. "Turbo sound", AY is adopted. Would it be possible to adopt the waveform memory sound? The issues are always time and space but I'm hopeful something can be done. Ther...

Re: Port system documentation updated

I see the general superiority of your (eastern, soviet, exUSSR, etc.) decoding scheme, but you seem simply incapable of understanding how it breaks compatibility. I do not know if this is a failure in communication, you being too stubborn to actually have an open enough mind to perceive the problem...

Re: Port system documentation updated

It doesn't cause problems for the Eastern machines simply because they don't need compatibility with legacy software accessing those ports in the wrong way. You are mistaken, in exUSSR computers, if possible, compatibility with old software is supported. Given example: Example 1. The demo often use...

Re: Port system documentation updated

The additional address line A16 is used selectively only when justified.
