Re: Copper horizontal wait problem

setting it twice shouldn't pose a big problem even for real Next, depends what exactly you did and how it fizzled. Updating "live" copper code can be somewhat tricky, for example you can overwrite "halt" instruction without having rest of buffer cleared/initialized and if all the waits are already p...

Re: Copper horizontal wait problem

CSpect + ZEsarUX (+ZESERUse fork) run the CPU until the left-edge of pixels is reached, then they draw previous pixel + right border + left border with *current* status of nextregs. So your change from horizontal pixel 64 is retroactively applied since pixel 0. I'm not aware of any emulator working ...

Re: New versions of everything

There's lot of development going on whole year... https://gitlab.com/thesmog358/tbblue/ https://gitlab.com/SpectrumNext/ZX_Spectrum_Next_FPGA it's just keeping the noise to regular users low, so not every medium-size advancement is released instantly. Right now the Next "distro" 1.4 is being on the ...

Re: Wireless controller option - will this work?

Both of mine M30 2.4g were very difficult to fit into the ports, very very tight (I was almost considering to take some sandpaper and brush them a bit). Also I was not sure how deep they should go, and because of my wrong config of the ports causing the controls to appear malfunctioning (button C as...

Re: Basic vs Assembly language

Watch the last video from Jim Bagley's tutorial series, it demonstrates nicely that even 28MHz NextBASIC could struggle a lot, especially if written in straightforward way. I guess one could rewrite his tutorial game in a way to make it perform LOT more better in NextBASIC, judging by what is possib...

Re: updating NextPi?

and you can upload+run anything from the Next (some shell script or even Pi0 binary) (including script re-mounting system FS as read+write and destroy it.. err.. update it), but the size of the update would probably make this highly impractical and error-prone... :)

Re: updating NextPi?

1) the plan is to build KS2 units with newer version of NextPi, postponing next update quite a bit (the KS1 units have still actual version of NextPi distribution, there was no further release yet). 2) I think there's built-in mechanism to update it from drive connected to the mini USB port, already...

Re: Wireless controller option - will this work?

I have two 2.4g ones (not bluetooth) (bought from eBay from some China based seller-of-all-sorts-of-stuff - worked like a charm), and I have no issue to pair them correctly and use them as MD1/MD2 on the Next. I did run into some issues while trying to make them work, like the manual saying to pair ...

Re: Hi from Australia - New to Spectrum.

phone number: write to email info @ specnext.com

(generally for Kickstarter backers it is better to use the kickstarter contact form from the campaign, but as you ordered one through the "eshop" web, just email them with details - if you have some order number/etc).

BTW welcome and have fun. :)

Re: Raspberry Pi 400

you can have "power/price" cheaper than Next computing device by pretty much buying *anything* on the market except the specialized stuff, which is also the reason why Next costs how much it costs. It's FPGA based board, suitable also for developing your own chip designs, and it's designed to suppor...
