Re: ABUG SOUTH 1 to 3 June 2018 (Hampshire) BOOKING THREAD

It was great to have a really good amount of space - both the desk space, and the free space in the room. A bit of a luxury - Leicester has to work with smaller rooms. But it would be good not to expand at all costs. I'd be tempted to suggest that a proportion of places - say a quarter or a fifth - ...

Re: Microsoft to buy Github

It may be they wanted the social network graph - they bought LinkedIn too. They know more about what people's interests are, and how one set of interests implies another. And what technologies are on the up, and who is leading the charge. The code and the wiki for a project can readily be exported, ...

Re: Coaxial problem

To the left of the BNC connector, on the back of the Beeb, is the RCA connector: that's the one with a signal suitable for a manky old telly's RF input (aerial input). If you connect to the BNC, you'll need to connect to the telly's composite input, which will be RCA style, or to the SCART with an a...

Re: RGB to HDMI using a Pi Zero and a small CPLD

It certainly looks very nice and should prove to be a popular upgrade!

I should perhaps bring my Samsung LCD round one day to see if it works well - or, are you already highly confident of supporting just about any monitor?

It's easy enough for me to bring it, and as it hasn't been powered for years, it won't have any high voltages inside. Until we test it!

Re: Computer Shops From Back In The Day

I've just had a flashback to that phrase "dial 01 if you're outside London" from radio and television (because life was more complicated in those days.) If you dialled 01 inside London, you'd get an error, apparently.

On these lines... I have a Vectrex, which doesn't quite work. Does anyone have the bravery and inclination to investigate? It makes the right noises at boot, so digitally it's fine. The CRT's heater element does glow, but there's no image at all. I thought possibly it could be an HT failure or CRT f...

Re: Computer Shops From Back In The Day

Which led me to check the astonishingly interesting history of UK dialling code changes - 081 was only used from 1990 to 1995, apparently. Not that shopfronts and vans were necessarily updated with any great urgency when numbers changed - as apparently in this case.

Thanks. It would be great if we could get some people from the 6809 community along. In the same vein, if we find ourselves with a comfortably large venue, this time or in the future, is there a Commodore community we could reach out to? KIM, PET, VIC and of course C64 are all 6502 machines of the ...

How much page zero space would you want? You could consider taking all of Basic's allocation, and copying it back when you're done.

That's fixed it! I think that might be a trick which tricky does quite a bit- perhaps it's now a trick too far? This slightly earlier post does the same, I think:

All I want to do is to set bit7 = !bit6; are there any cunninger ways?
Is bit7 already a known value, like zero for example? Or is it initially the same as bit6?
