I think you missed the boat, though there is another boat getting ready to sail in the form of the MGC Mk II. Dave H (daveejhitchens) will be along shortly to give you details, no doubt. :D

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

Depending on how long it takes to repaint the screen, you might miss the next vsync pulse. This would mean dropping alternate frames, and running at 25Hz rather than 50Hz. Depending on the application, this may or may not be noticable. I was thinking that it would run at least one frame too late, p...

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

I thought I'd pose a random question which I hope hasn't been asked before. Would it be possible to decode the output from the last 32 lines of MODE 4 on the Electron and transform it into text that filled the entire framebuffer, or doesn't the Pi have enough bandwidth for anything more than scanlin...

Re: Electron Cassette I/O

Another phone wouldn't even detect the cassette lead when I plugged it in. :( On the positive side, I tried it with a tablet and it still worked. H...

Re: Greetings from Wiltshire

Interesting idea to use the cassette port, was just thinking back to the days using the printer port to drive the robot, wondered if i could connect it to a arduino or pi to capture key presses.... With the printer port, just redirecting the VDU output should just work and would probably be easier ...

Re: How I use beebasm to build my games (with a .bat file)

No, it is very simple and encodes up to 128 uncompressed or repeated bytes from anywhere in the last 256 bytes. If you have the same eight bytes repeated eight times, you would have 8 uncompressed bytes and then 56 repeated bytes starting 8 bytes before, so as they are copied, they intern are copie...

That term really annoys me as 'left' is *not* the opposite of that meaning of 'right'.

He would have been the author of the computer software I think. Yes, he seems to have vanished from the web a good few years ago.
