Re: Welsh Meters

He he, nice one guys. But be careful - we know to our cost in Wales that Google translate is responsible for producing some of the worst and most confusing road signs here in Wales, in fact there's a whole Facebook group dedicated to Arwyddion Cymraeg Gwael (Poor Welsh Signs) where the words in a s...

Re: Asymmetric multiprocessing...

So, just out of interest, what term or name do the QL community use to describe the original Sinclair QL which after all already has two processors as standard (the main 68008 and the IPC/Intel 8049 microcontroller)? To be fair, the IPC and 8049 can not be reprogrammed by the system, cannot run use...

Re: Asymmetric multiprocessing...

@Nasta I have never said that a system using dual port RAM should not be considered. In fact shared memory systems have been around for a long time. They just used very careful control and timing as years ago dual port RAM was very expensive. Various 1980s computers either use shared memory for IO d...

Re: Asymmetric multiprocessing...

I don’t think there will be very much interest in this subject unless some software is developed that makes good use of the concept - a killer app so to speak. But anyway... The documentation clearly shows that the Acorn Tube is designed around using the BBC operating system, and this extends down t...

Re: RGB to SCART Video * solved *

TV standard CRT monitors just need some adjustments or modifications to the horizontal time base circuitry. Of course, this is easier said than done on most of them. *Some* LCD monitors that can handle TV standard video have nearly enough adjustments. TVs often don’t have any provision for any adjus...

But then I only got interested in them In 2011... I think somewhere on this forum I posted a picture of a QL circuit b...
