My primary school was clearly behind the curve when it came to using computers in education. I can distinctly recall being shown the TV programme and having to write a short story describing what happened in Mr Magus is Waiting for You, but I don't think I had a single lesson in my entire primary ed...

Not the most interesting of questions I admit, but I could still do with some advice. I have a Master whose feet have degraded to the point where they leave a strange sticky black goo over anything they touch. I've got some replacements, but I'm actually not sure how to replace them. Can anyone offe...

Two Amiga A2232 serial cards...

Anyone want to hazard a guess what I'm going to do with them?

Given that it has '1770' written on it, the board looks like a floppy disc controller to me. BBC Micros needed them fitted to be able to talk to disc drives. BBC Masters had them built-in. As for the crackling and the smoke, it's an extremely well-known issue. There are some capacitors in the PSU th...

All in my main development Master 128: Tube Internal: RaspPi CoPro Tube External: CMorley's Tube Serial adapter connected to Tom Seddon's BeebLink, for uber-fast filesystem access to my Mac when doing development. Tube external pass-through: For testing various CoProcessors! 1MHz bus: Connected to i...

Well, last week one of my colleagues gave me his old Master 128 and disc drive in exchange for me promising to make a donation to a charity of my choice. Asking friends and colleagues if they have old unused computers can certainly pay off. (Still haven’t found anyone with an ARM Evaluation System t...

Quick question, is the MIA list up to date? I've recently taken possession of several boxes of software and I'd like to see whether I could contribute missing titles to the community instead of putting them on eBay! It would also be incredibly useful to have a list of MIA educational software (alrea...

I'd buy it too. In fact I'd probably buy any new game released on the Beeb!

Some gotchas / things that could be improved: [...] I could run the build commands from directly inside VSCode and/or use proper make - old habits die hard, I guess :- [...] You can do this. The tasks.json file inside the .vscode folder defines what happens when you 'Build' and/or 'Run' in VSCode. ...

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.
