I am far, far, far from an expert, but it looks to me as if there might be some kind of threading issue at play. Some OSs are more tolerant than others of UI API calls being made on non-UI threads, and those 'closure_invoke' calls in the call stack would seem to suggest some kind of concurrency syst...

Bloody brilliant, garfield!

The oven is on...there will be fruit loaf and lemon drizzle cake, so we'll all be able to get our five-a-day!

Pity the poor folks who can't turn up until late evening!

That is a real shame, the annotations really added to those videos and provided so much context. Looks like Youtube removed them permanently a year ago. I seem to recall I used a third-party application to download a few Youtube videos a few years ago and the captions didn't end up in the video file...

Out of curiousity, what would happen if you fed the monitor with the wrong signal, ie analogue when it was expecting digital or vice versa?

If I sent you an appropriately prepaid stamped addressed padded envelope could I have the Archimedes Assembly Language book?

Thanks everyone for your replies. And B-Em does too. Again I am not sure how accurate the emulation is. I am also not sure what the benefit of making the emulation cycle accurate is. Is this just a technical challenge, something you want to do? Or is there some piece of software you want to run that...

Hello all, At some point starting in the Summer I’m contemplating a project that would target the first ever ‘released’ ARM, specifically the one inside the ARM Evaluation System. However, this would entail either being able to accurately emulate one (and it would need to be cycle-accurate both with...

- The pink chest is a piano! (An amazingly tough piano, admittedly.) Fascinating! How do you know? (Not doubting you for a second, but I've never heard this assertion before!) The piano is mentioned in the Novella, it belongs to one of the crew members. One of the other walkthroughs I read mentione...

Fantastic write-up Bilip, and some other very interesting observations here. I got as far as the bottom of the windy shaft on real hardware back in the day, and completed it once or twice under emulation a few years ago. I have still to do a complete run using the 'proper' solution (no physics engin...

Until you realize that the Electron has an always-on interlaced PAL frame with two differently timed fields. And you have to find a way to determine which field is active. And you need 100% cycle counting in your timing critical code. ... sounds horrible but not *that* bad so far... And you realize...

You could look into git submodules for this. They’re often used to make repositories that ‘contain’ or ‘link to’ other repositories. They’re not without their problems but when configured and used appropriately it can be the right solution to this kind of problem. I’d echo what was written above tho...

Full table for me please, Friday to Sunday. Very much looking forward to it!

I’d like to bid on this for my CoPro collection. If I win I’m very happy to bring it to ABUGs, help with imaging the ROM, etc.

The board needs photographing and the ROM imaging :/ has anyone been in touch with the seller to ask if, whoever buys it, can be put in touch with us to help do that? I have contacted the seller on eBay and asked whether they’d be willing to tell the winner about the interest from the StarDot folks...

PM Sent!

Well it hasn't gone for almost two million yet! I have a suspicion the price may reduce somewhat before it sells.

Hello @SirBod,

Did you ever manage to get hold of the Scorpius source or a build with a playable ice level? It’s one of those games that I remember being really excited by, all those years ago.

I bought it and played it. To be brutally frank, it was a let-down. As others have said, it basically consisted of flying from one star / planet to another, over and over. Having read all the hype about how the full game would simulate an entire galaxy and have all kinds of alien races etc, playing ...

Are you on a mobile? I’ve found that quite often when I’m viewing a web page on a mobile phone the image resolution is reduced for large images.

MAIN DEV CHERRY MASTER: (Not had time to take lid off yet but if it is similar to the other one I own, it’s got a Toshiba CRTC. Will check VIAs soon and update!)

I'm afraid my one and only Electron is locked away at the moment otherwise I would run the test! I just wanted to say that when I've been trying to get stable raster effects working I've found it very useful to have some lines on the screen that are actually part of the screen memory, not just creat...

Pretty positive if you took a close look you’d be able to find some software in there that isn’t GPL and where the original creator still retains the copyright!

(Although I am in no way a lawyer or a software licensing expert!)

As someone who's just spent several hours iterating on various combinations of cycle timings in an attempt to get a prototype effect working, may I say: many congratulations. And on an electron with no nice timers to help you out, and interlaced... seriously impressive. Looking forward to seeing wha...

Does anyone know if the CCH car park is open late, ie up to 11pm or so? I can't leave (South) London until around 8pm so I'll be getting to Cambridge rather late, but I'd really like to unload my stuff on Friday evening (and perhaps risk leaving the car in the car park as well).

You wouldn’t happen to have any of the devices that plug onto Atom motherboards to provide video output? You had a quick look at my two Atoms a few ABUGs back and I made a mental note at the time that I needed to get hold of some! You mean connectors for the composite out (PL4), if so yeah could pr...

No, rescue the poor slowly-corroding Master!

I have one, next time I’m in the vicinity of my collection I’ll dig it out and see what documentation came with it. Is there a list of hardware / software that are considered important historically and haven’t been preserved? I know about the MIA games list but are there equivalent ones for hardware...

Making considerable progress! I will post here with what I had to do to get things working shortly... I'm trying to work it out by looking online but does anyone know which areas of memory (workspace) I might need to preserve when using HostFS / UPURSFS? I am trying to run a demo (Wave Runner) over ...

Thanks Martin. I seem to have got it working! For those who might want to try UPURSFS on MacOS in the future: - The -U option didn't work. I had to use -s. ie: perl ./TubeHost.pl -s /dev/tty.usbserial-FT93UCZ7 115200 - There seems to be a bug on MacOS whereby if you have the FTDI USB->Serial cable p...
