Rob, Ample or the M5000?

Sorry - I didn't mean my post to sound authoritative. I just remembered reading the piece that was subsequently posted and thought it was interesting that Orlando had considered the idea.

Let's hope someone does because it really should be capable of some fantastic game & demo music.

I read somewhere that Orlando was looking at using it to produce music for a game but abandoned the idea as it generated too many interrupts.

I've got two or three of these (the ones that fit over a Beeb but are just the metal plinth i.e. no drives).

It's neat, but it's not doing anything magic. All it's doing is exploiting the fact that sin π = 0 . If you start the program with P > π, you'll notice it converges on the nearest multiple of π. Not quite - it'll generally converge to the nearest odd multiple of π unless you land bang on an even mu...

You can visualise the convergence of these dynamical systems, where you iterate x=f(x), by plotting the function (y=x+sin(x) in this case) and the line y=x. You then choose your start point on the y=x line, draw a line vertically to meet the curve f(x) and then draw a horizontal line back to the y=x...

@RobC do you mind if I implement compatibility with your VideoNuLA? Can you share the programming details? Hi - no problem with this. As others have said, hoglet has already done this using the details in the manual. I'd appreciate a name check if you release anything :D I'm happy to try to answer ...

On the RIscPC I did write the software to using the x86 card as the FPU. So if you have an 586-133MHz card that is probably the fastest FP Acorn machine.

Was this the one marketed by Warm Silence Software? I've looked around for it for years but it seems to be MIA.

The Jessop Ralph will work with the Acornsoft Logo Extensions disk which is on here somewhere. I may also have the original software as I picked up a load of Logo/control software with it but many of the disks were mouldy. I have a control box and am happy to buzz out the cable and/or help with draw...

So does your BombJack

Sadly, I suspect I know which one will be completed first

This looks excellent

I'm sorry that I'll be missing this, but I have hurt my back (carrying Beeb's and CRTs) and can't face the drive. Enjoy your selves and share a pic or two for those of us their in spirit Sorry you couldn't make it tricky and hope your back improves soon. My daughter did play your Frogger for a bit ...

Was it a Touchmaster tablet ? I think these have both user port and serial interfaces. I have a couple of them and may have some documentation somewhere. No idea, they were selling it under their own brand, the specs are here: https://www.4corn.co.uk/archive/showpdfs/07%20Acorn%20User%20July%201986...

Just a bump to say that the RISC OS SW Show is today at the Arnos Manor Hotel, Bristol.

There should be a few of us from here at the show so, if you're able to make it, it would be great to meet up.

I know this is very late but I was backing up my DC hard drive tonight and realised that I had Technocad installed on it.

Here's an ADFS disk image with the TCAD folder on it - it should work but I haven't tested it. (I'd have imaged the floppy if I had a convenient way of doing so...)

I don't appear to have any documentation on the tablet protocols but I will try to find the relevant parts of the source that deal with the tablet. Was it a Touchmaster tablet ? I think these have both user port and serial interfaces. I have a couple of them and may have some documentation somewhere.

The OS 1.2 disassembly might be a good starting point. VDU 22 ends up at CB33. Here are the lines where it's setting or doing stuff: CB3D STX &0355 ; Save current screen MODE CB43 STA &0360 ; Set current number of logical colours less 1 CB49 STA &034F ; Set bytes per character CB4F STA &0361 ; Set p...

Not sure about gettig hold of RO 4.05 but it may still be owned/sold by Q3D.

However, it might be worth PM'ing 'Paul' on here as he's taken various bits of Millipede kits to various shows in the past.

So, I've heard back from Richard. We've got two tables - last year each table was big enough to hold a couple of machines with monitors etc. I'll only be bringing one M128 so there should be enough space for three other setups. The room will definitely be available from 9am but may be available earl...

What time do we need to be there to set up Rob? Do you know how much space we have - I'm wondering what to bring?

Not had a response from Richard yet - I'll mail him tonight.

I did notice it pulls in some strings of 10/11 numbers which aren't telephone numbers (eg. "0123456789.pdf" etc)

I worked on a similar problem once and used probabilities derived from order statistics to flag up cases like that.

Does it show with *ROMs (sorry if you have already checked). I think that the slots can be jumpered out, but may be making that up! I think only slots 4,5,6 & 7 can be jumpered out with each jumper replacing one of the two sideways RAM banks with one of the 32KB ROM slots on the PCB. The cartridge ...

It's a lovely looking thing.

The keys and case seem to have a matt finish but, on the previous images I've seen, they look glossy/shiny. Is it just a trick of the light or has the finish been altered?

Thanks,

Rob

Just giving this a little bump

If you'd like a stand (or to share one) and haven't yet contacted the show organisers to let them know, could you please say so here so that I can confirm numbers to Chris?

Thanks,

Rob

Chris, the Wakefield RISC OS show organiser contacted me yesterday to ask whether any Stardot/ABUG folks are interested in having some tables again at this year's show? The show is on the 18th of April: http://www.wakefieldshow.org.uk/ If you're interested in exhibiting, please reply in this thread ...

The Beeb does not have a -12V supply. It is likely that the -12V supply is used only for the serial communications. So it is possible that the Beeb’s-5V output is connected to this ‘-12V’ connection. However please note that this is all just speculation... I'll test it tonight to see what voltage i...

Edit: I’ve found the real manual online, which is rather more substantial than the pamphlet I got with mine: http://chrisacorns.computinghistory.org.uk/docs/Cumana/Cumana_TouchPadUG.pdf The pinout for the 8-pin DIN is actually at the end of that document. However, it lists -12V as one of the inputs...

... a Cumana tablet for the BBC Micro So... no cables, no instructions, but the cassette loads a graphics program so that works. Basically no idea where to start with this. Google isn't giving my anything either. Lots of questions to answer including how to connect to Beeb from the 8pin DIN socket ...

That's lovely - great job

Hi, I am still making them but usually to order and as time allows. Lack of time has meant that I'm not making as many as I used to so I've not sold any on eBay for a while but I'm always happy to make them up for folks on here. Unfortunately, I don't have any in stock at the moment but I am plannin...

Does it change the palette in various levels too? I noticed that but wasn't sure if it was supposed to or not!

Pretty sure it does although I haven't played it properly since I was a kid.
