That would certainly be very helpful to me.

As promised then, hopefully it is of some use!

Hi all, Github/git has come up a few times in various discussions, and often in the context of folks who have some source code or a project they want to publish in the public domain, but are perhaps put off because at first inspection the world of git and Github can seem a bit overwhelming. I though...

What are the pros and cons of doing that rather than using my own GitHub account, for example? I always think of StarDot as being closely associated with Acorn, and 'my' BASICs (unlike Brandy for example) are absolutely not! :evil: An excellent question. There are no right or wrong ways to go about...

Thanks, I think I'm going to journal what I do, in the event its helpful for future hardware beginners like me. I recommend that you open it up and carry out a visual inspection by eye (under a good light) looking for any physical trace of the cause of the smoke, such as soot marks, blackened, damag...

If you think it appropriate Richard, your project could be easily added as-is to the stardot GitHub organisation alongside other open source community projects. Github is actually quite straight forward to use once you acquire a few bits of know how, and I'm continually impressed with how collaborat...

Resurrecting this thread in the hope some kind folks could help out a non-hardware-techie type like me with fixing an old A310 I bought on gumtree. The seller wanted to show me it working, but when he did, a bunch of smoke came out of the machine so he offered it for just a tenner - bargain! :D So, ...

Having worked on official Peppa Pig games, I can say that they do endeavour to protect their copyright but not that aggressively - there were at one point a whole slew of knockoff Android PP apps. Realistically, rights holders aren't going to eat the cost of enforcing against hobby projects like thi...

Pretty sure I have this. Not sure when I'll get a chance to download it though, but will try over next week.

Agree with Rich. This is crazy good for a beeb. Amazing work tricky. Would love to see a 'how it works' type blog if you ever feel so inclined.

Not sure if already posted on here, but I noticed that John Kortink has been building up a HDMI converter for the Beeb...

I had a look at the site, deflemask seems to be supported & life on the forum... have you contacted the devs to see if they can add 4Mhz support? It might be as simple as adding a row to a config struct for them. Chris That's a good idea. Certainly would be handy to be able to export VGM's that...

Definitely great to hear that there's interest in new music for the old Beeb. I am noodling away at a 6502 music player for Deflemask DMF files, but it may take some time! DMF is not a very compact file format, and cant be used 'as is' because it is gzipped, so some sort of file format conversion wi...

Thread Bump! I've added a few notes about the musak! Hopefully interesting! Enjoy.

Ok, following on from kierans lead I'm gonna reserve a post here to talk about the musak bit of the demo! 😃 Righto - so I've done up some notes on how we did the music for this demo, and added it to GitHub. Generally the music playback for twisted brain is the same as all of our other demos, we calc...

Unfortunately I can't attend this now (boo), but if anyone else wants my £50 ticket to join Kieran they are welcome to go in my place. PM me if interested.

This is very cool - great work Chris!

The variant in the Master System and Game Gear has a 16-bit shift register rather than a 15-bit, but it's embedded into the VDP so it's not necessarily drawn from official blueprints. This is actually a good improvement by Sega for the MS/GG, since it means that the periodic noise is exactly 4 octa...

This SMS Power link has been extremely useful for me over the past couple of years, while I was messing with sound chip things. In a correction to my earlier post, it appears that setting a tone register to 0 creates a continuous output (not 1 as I previously posted). Which makes sense as the chip u...

As Daniel says, gpl is fine for community projects like this. I tend to use MIT license for most of my beeb stuff as I'm really not fussed what happens to the little bits of code I'm putting "out there". For your tool David, I'd suggest something like this to get you started: 1 - set yours...

Yes, the SN data sheet says this: 7. DATA TRANSFER The microprocessor selects the SN76489AN by asserting !CE (active low). Unless !CE is asserted, no data transfer can occur. When !CE is asserted, the !WE signal strobes the contents of the data bus to the appropriate control register. The data bus c...

There are some unanswered questions -- are the assumptions correct? Why does changing the volume (of a square wave) let you play back samples at all? (The average speaker cone position should be "in the middle", regardless). Are the channels really added linearly? I seem to remember that ...

Listening in on the high precision audio technicals being discussed here, I'm amused by how little we knew BITD - in fact I think we got pretty lucky with the samples we did on the various yorkshire boys sample demos. It certainly wasn't because we understood the hardware that well. In fact, I belie...

I read somewhere that craft cms has an ecommerce plugin. Not used it though so can't vouch if it suits your needs.

I used to like Perl quite a lot, but then I discovered Python, which is much more structured and easier to interface with underlying systems and binary files. Appreciate it's not everyone's cup of tea though, and it does take a bit of getting used to at first (wot, no braces?! :lol: ) David B's scri...

This is really great David. Given that I was considering writing such a tool from scratch, you've accelerated the process significantly. You mentioned you'd be open to sharing the source, which would be really fantastic for me just now as I'm particularly interested in finding a way to get my A5000 ...

^^ this. I mean, .inf files do get a job done, but I've never really warmed to the idea of them. And spaces in filenames really isnt even a thing anymore. So a neat tool that lets me pack all my acorn files into a nice image, preserving file types etc., instead of lots of bitty PC host files, sounds...

Sounds great David. It's been brilliant to see how much community effort has enhanced open sourced projects like BeebAsm and B-Em.
I actually much prefer c# over c++ for getting stuff done quickly. Plus I believe .NET apps can run just fine on Mac/Linux using Wine.

On a related note, since these days a lot of modded systems use CF or SD cards, does anyone know if it's easy to parse the .img files you get from a CF card (using a tool like win32diskimager) as an ADFS HD image? I presume they are low level byte copies of whats on the card, but not sure how the da...

This looks very promising! I was thinking recently (since I'm archiving a lot of acorn disks) that a tool like this would be super useful.
Out of interest - do you have any plans to open source it? (via Github etc.)

Loving the gallery disk!
