Re: ZX Spectrum Next in Flux

scores/lives display etc., and that layer 2 is CPU intensive - presumably because byte per pixel means more memory writes (/reads) ? Yes - the traditional spectrum display is only 6912 bytes but the layer 2 display is 48k. Like the ULA display, there is a contention going on with layer 2 so even th...

Re: ZX Spectrum Next in Flux

Does anybody know if this is this the way it's going to remain? i.e. there will be no 'fixed' hardware or should I say firmware (or distribution?) like it was for the original Spectrum, and instead it will be constantly evolving with new features being added periodically? While it's exciting to hav...

Re: What are your current Spectrum projects?

You misunderstood my post. The only reason why I was using Z88DK was SP1. If I'm going to use the SDCC compiler in Z88DK, I rather use SDCC directly. There is a big difference in sdcc on its own and sdcc within z88dk (called zsdcc). Many of the code generation bugs in sdcc have been addressed in zs...

Re: Questions about FZX

AA has greatly extended the capabilities of the FZX driver in z88dk, and also provited a stdout crt that uses it. But I don't code in C either. I'm pretty sure you can get z88dk to emit intermediate asm, which you could incorporate into your own framework. But that seems too fiddly for me. z88dk is...

Re: ZX Spectrum Next Discussion

I thought it was 130-140, give or take a few, as that's the number that backed the "Just The Board" option on Kickstarter. Do you know where the extra 250+ came from as I didn't think they were selling the board outside of Kickstarter? After the kickstarter closed, they made it possible for people ...

Re: ZX Spectrum Next Discussion

I'm not underestimating the amount of planning and other work needed, but at least you wouldn't.need to create the electronics from scratch As long as backers knew from the start that it was based on a Pi they could make an informed decision. The risk in the project is in the physical case. The kic...

Re: ZX Spectrum Next Discussion

This already exists, but with an older version when both systems shared the same FPGA and it was called TBBlue. http://www.zxuno.com/forum/viewtopic.php?f=47&t=491 That was a very early version which wasn't much more than a standard zx spectrum implementation :) The next cores the early devs were u...

Re: ZX Spectrum Next Discussion

My opinion is that people behind crowdunding projects are often enthusiasts good at their passion (programming, soldering, designing) but just as often are lame at "making business". It they were good with business, they would be able to secure money for their project in traditional way (like takin...

Re: ZX Spectrum Next Discussion

The only thing that disappointed me is the lack of ULAplus, and only from "political" issues. Also, it's supposedly fully open source, but when the sources were released a couple of months ago... the VHDL code of the FPGA core is mysteriously missing. And the lack of additional cores, that big FPGA...

Re: ZX Spectrum Next Discussion

There are about 400 boards that have been out almost a year. I have one and can say it's a great machine and a lot of fun to code for. Failure to reply to questions about delivery dates or name a current delivery date. Failure to update backers regularly (it was supposed to be every 2 weeks) The del...
