Re: How much longer?

Winfield: we all want keyboards that work well enough. I was just pointing out that comparison to the Vega+ is definitely unfair. I think that we will eventually get a proper system with a keyboard that works well enough (noting that most modern computers don't have good keyboards).

Re: How much longer?

JoeZX: I have a *working* caseless ZX Next. It is a beautiful piece of machinery that works pretty well. It has a keyboard jack for a PS/2 keyboard, and so will the final machines. It is the appropriate size to fit in a standard ZX Spectrum case and has a standard ZX Spectrum keyboard connector. Peo...

Re: zx spectrum next

The copper is feature that can automatically manipulate the registers of the ZX Next according to the screen position being drawn. It is basically a reduced version of the Amiga's copper. If you look in the Wiki you can find all of the extra instructions. DMA just allows movement of data without CPU...

Re: "PiTubeDirect" Pi co-processor system for BBCmicro (at FB)

Having looked into the functioning of the tube interface on the BBC Micro, I can tell you that you have a set of (memory mapped) I/O ports that allow communication between the BBC Micro and the CPU on the tube. Basically you are right, you pass code through the interface to be written into memory lo...

Re: Had no trouble reading the specnext group

People don't generally understand how the device actually operates. They visualize what would happen if the Z80 in Spectrum could be run at 100MHz (or more) without all the additional issues. They see everything running 32 times as fast. This isn't helped by the fact that well behaved programs on th...

Re: Making ULA screen transparent

you need to make the paper color you are using the current transparency color. The simplest way to do this is to set the default paper color (dim white) to $e3 (8-bit colour). To do this: nextreg $43,$80 ;; select ULA primary palette for changes (no auto-increment) ;; primary palette active for ULA,...

Re: Simple Sprite editor (update to 0.4.1 10.11.17)

If you are simply splitting image files into sprites or tiles. I have a set of command line tools which include a command to do this. My tools support the full 9-bit palette. What my tools don't contain is a sprite or tilemap editor with the idea that you will edit them in another tools then use the...

I have created a set of tools to aid in cross developing for the ZX Spectrum Next currently called zxntools. Currently the tools do three things: generate sprite and tile data from an image Convert images to raw ZX Spectrum Next formats for use as loading screens Contain an extended version of NexCr...
