Re: Spectrum Next: Status of production

A KS update has just come out. The first 1000 keyboards and cases are being air shipped to the UK to get the assembly running as soon as possible. It is hoped that this means the first nexts will be shipped before Christmas. The assembly process can only put out x units per week as it's too expensiv...

Re: PI Used as Audio Card for ZX Next

The interface to the accelerator board from the Z80 side is only UART (however, it seems that the state of GPIO pin can be known by the extended CPU instruction). It seems that the communication between the app called “NextPi” and Z80 is limited to the exchange of messages through the serial port o...

Re: Next Game Music Wanted

Now I know which game it is :) Just FYI, in case you aren't aware: SNA is considered legacy by nextzxos so it will put VGA modes into 48k or 128k timing depending on the size of the SNA. It will also turn on contention and the z80-dma compatibility mode (dma transfers will be one byte more). Of cour...

PI Used as Audio Card for ZX Next

The video shows a terminal program running on the next connected to a bash terminal on the pi. Commands are sent to the pi, in this case to play various audio formats (sid, mp3, etc), the pi generates the audio and sends it back to the next via a stereo i2s interface. The digital audio sent by the p...

Re: DAAD Adventure Writer and ZX Next

The clipping approach has an issue: if the game have some rooms without picture, then the whole screen is used for text, and my code won't be called so I cannot remove the clipping area in ULA layer, what would lead to see half screen in black. So you can't clip the ula below the layer 2 area when ...

Re: DAAD Adventure Writer and ZX Next

You can't disable transparency but you can do something else. I see that there is nothing behind either layer 2 or the ula. So you could do something like make the transparent colour black and then make the fallback colour black as well. If nothing puts a pixel someplace (maybe all layers are clippe...

Re: DAAD Adventure Writer and ZX Next

Can't even recall how long ago that was, I think the cards have now something like 2.00.12 +- ... But I recall "it was the last time, there's no more budget for another rewrite" ... I can't remember when that was either, maybe when the pcbs were first made and some tests were done? There has been a...

Re: DAAD Adventure Writer and ZX Next

About transparency, I'll let the user (the writer) choose wether to use it or not. If he doesn't know how to create a file with transparency or he just doesn't want to, I will make sure the transparency register has a value different from last palette entry. You will probably want to reserve one 8-...
