Is there any more information available on this core?

There is this link...
https://gitlab.com/victor.trucco/zx-spectrum-next-cores
It says that they are cores based on ports for ZX-Uno and have come from different sources, copyright has been kept on each file.

The ZX Spectrum Next has an Atom Core too (photo stolen from Facebook)....

perhaps -B- (Neil) likes to visit this event?

He lives pretty "close" to that address.

Indeed. Only an hour away depending on traffic.

I could bring my Atom and maybe my Elk.

Neil.

Sounds good. I wonder if my old car will make it that far south.

Neil.

Excellent stuff!

Excellent work again!

Do you know what pixel clock frequency the QL uses? (It seems to be 10Mhz from online info)
Also how many clock cycles are there in a video line? (This should be around 640 but may vary 1 or 2 either way)

This might help...
Neil.

I have a couple but I’m not in the UK.
I will be for Christmas though, so if you’d like me to lend you one....

Neil.

Have you tried the QL yet, with its famous overscan in monitor mode?

Excellent work

Amazing!!!

That's very neat, I assume it works OK? (I was concerned that the extra heat inside the PI case might make the threshold adjustments a bit unstable.) It's not actually finished, I got to the stage where I needed to programme the CPLD but my Xilinx platform is not recognised by my laptop. I will hav...

Ah, you beat me to it. I am using your ZX81 circuit with the old version of the board...

Neil.

Excellent! I like the look of that. Especially since my Xilinx programmer doesn’t work any more.

Nice work

I'm also interested, I have a bog standard Elk waiting.

Neil

I use a Philips screwdriver for the 3mm holes and one of these for the 4mm and deburring. By hand, not with a drill.

Here’s some quick measurements of my box.

.... or someone could measure their box when they get home from work tonight and post the results here?
(I am volunteering).

Neil.

Good work fella!

Nice work fella

Well hello, fancy seeing you here!

Excellent news. I look forward to some AGD releases for the Elk.

Neil.

This Rob Hubbard SID file is the ultimate SID tune ...... download/file.php?id=8067

That is amazing. I wish I had used that on my video!

I finally got around to finishing the AtomSID board that Kees gave me at the Dutch Atomic Techsat in June. I have modified it slightly. I am usung a SwinSID so it runs off 5v making the step-up voltage area of the board redundant, so I cut it off, removed some tracks, made some links, moved some com...

Thanks but I already checked the wiring of the encoder and the switch is working. So I’m thinking it’s either the card setup or actually something wrong with the micro Gotek itself. I was surprised when it turned up in a Jiffy bag. I could try it on a different system and try and rule out the card o...

The little PCB that the encoder sits on is simply for linking the encoder's pins to a 4 pin header. If that helps.

Hi All, I have bought a Micro Gotek by Zaxon from SellMyRetro: https://www.sellmyretro.com/offer/details/micro-gotek-32413 I have dropped a few of Kees' .dsk files on it from the AGD packs for testing but I am not having much luck with it. The connection and jumper details are here http://www.eightb...

Welcome! This is a fantastic forum for info and help.

Your story of abandoning modern gaming and collecting classic 8-bit systems will sound familiar to many here. Although some, like me, may not have tried modern gaming at all. I'm more into the hardware side of things anyway.

@Neil did you manage to source a board?

I received one of Kees’ PCBs while at the Dutch Atomic Techsat a few weeks ago.
I’ve almost finished it but I’m on holiday at the moment so everything is on hold and no retro computing of any kind is getting done.
