Matt Godbolt's talk at CppCon 2019 about Compiler Explorer is quite interesting if the internals/behind the scenes of compilers & Compiler Explorer appeal.

I use CE with the GCC 6502... sadly op-code highlighting still hasn't been fully implemented. A simple oversight I am sure...

I'm going to plonk this down here because I think it's relevant to Beeb owners in what also been a great year for gaming for them. Stunt Car Racer surprised everyone. And now it's the CPC's turn with a port of Pinball Dreams. Batman Group have leveraged the same CRTC chip the Beeb has to do something astonishing. 50fps scrolling and sprites on a machine with no official hardware to do such a thing.

https://www.youtube.com/watch?v=KOUXfN8_hJ4

Whatever the secrets are, if they are indeed CRTC related I hope they can be shared with the Beeb guys so they can leverage this amazing tech.

And I can't stress this enough. You can look at the video but you have to PLAY it to get the full experience. I've been going back and forth between the CPC and Amiga versions. They "feel" the same. That's quite an achievement.

Good. Watched while washing up and emptying the dish washer. Matt’s talk are usually interesting even when I don’t understand them. Well I understood the middle bit about clouds as that is my day job, but all that C stuff ......

So the historical record doesn't become even more muddled, can I confirm that I wasn't one of the representatives from the BBC who visited Acorn for that original demo (the famous 'wire cutting' scene), despite what all three guests seemed to think at around 53:30 into the video. I believe they were in fact John Radcliffe (Executive Producer, Continuing Education) and David Kitson (Head of Studio Group, Engineering Designs Department, and my boss's boss at the time).

I think it was Chris that floated your name, I am not sure there was a huge consensus though. I think you are safe. Maybe.

Plus half the time the three of them had conflicting memories of things any way. And can’t say I blame them, I wouldn’t remember work events from 5 years ago let alone 30-40 years ago.

The only other name they came up with was David Allen, but they (rightly, I think) concluded that he would have been unlikely to attend such a 'technical' meeting.

Not beeb/6502 based and probably not of wide interest, bu I find it interesting.

Thanks for linking to that video. It was great.

First video I’ve seen that’s an accessible (if brief) story about the birth of BASIC that puts faces to the names Kemeny and Kurtz, who always seemed to me to be somewhat obscure figures in the history of computing and not the icons you’d think they’d be.

The one thing the video lacked was a bit more detail about what a BASIC program actually looked like and how it worked, perhaps comparing it with its equivalents in DART and ALGOL. Still a great watch though.

:idea:

Was at the Aussie Floyd (Pink Floyd tribute band) gig this evening and they used this video to back their performance of ‘Welcome to the Machine’. There’s a few Acorn/BBC references in it :-)

Thought people might enjoy it…

"SUPER MENU!"

In the year 6502AD...

... here's a great 30min presentation on a great work, the construction of a plug-compatible homebrew 6502 CPU in TTL devices. For Drass, the presenter and chief designer, it was the first hardware, first PCB, first soldering - and it worked! At 20MHz! Mostly surface mount devices too.

He really wants to have a go at those with rather more liquid than just that which is in a cotton bud. The battery gunk will be all under the components merrily eating away...

The battery cleanup in the Acorn video is heavily edited. Presumably because he's covered battery corrosion repair extensively in previous videos on his channel & this video was nearly an hour! Gadget does do far more than a quick wipe with a cotton bud.

I personally rinse with water in the kitchen sink after the vinegar to wash the acid completely away.

I think this video was presented in a format tuned for his regular viewers who've seen hours of cleaning and corrosion repairs! Perhaps he had not considered he'd draw a new audience, with the Acorn machines, who won't have watched his Amiga content?

Fair play, I was just going on what I saw in that video :)

There are lots of horrible lemon-juicy, just use IPA, baking soda etc, battery spill techniques that circulate on the interweb which won't actually stop the corrosion in the long term or might make things worse. Personally I think any opportunity to go into a bit of detail and disabuse people of these things should be taken, especially if you've got a big audience :)

With hindsight one of the few good things Amstrad did on some of its earlier PC clones (PC2000 series) was to use AA batteries stored in the top of the case instead of batteries on the motherboard.

Check this video out from Retro Man Cave:
At 13:34 .. there is a partial view (from a museum in Leicester) of an Acorn Atom Colour Turbo. I've never seen nor heard of one as an actual production machine. It's not actually mentioned in the video, where people are talking about Amigas.

But I'm intrigued..

Anyone know about such a thing?
..I'll be at the Virtual Acorn meetup for Cambridge Computer Museum May 16th 2020

The keyboard also isn't an original Atom keyboard so it sure looks like a homemade Atom.
