Re: Anyone remember a four colour ballpoint pen plotter?

I had the Tandy one (not seen it for 30+ years) and wrote a few screen dump programs for it. I remember one that drew small boxes for each pixel and one that drew lines of repeated pixels, then, at the end of the line, drew them back the other way to try and get the full line width as sometimes the...

Re: Anyone remember a four colour ballpoint pen plotter?

I used to have the Tandy one. It was ace. I used it with the spectrum, with the centronics interface on the Wafadrive. I think the printer might have had serial too. I used to do all my mum’s business invoices on it(!). It was also great for printing cassette inlays in 80 column mode. I wore it out ...

Re: John Kortink's BBC HDMI

My understanding is that the Raspberry Pi Foundation have already paid the HDMI licensing fee. By selling it as a self-assembly kit without the Pi, Ben (and presumably also Dave) does not need to pay the licensing fee a second time.

Re: SCART image quality

The Spectrum and ZX81, as Mark will confirm, output a non-standard video signal (missing or nonconforming front porch and back porch) for reasons best known to the costcutting bods at Sinclair. It's possible to do extra mods to make them play nicer with modern TVs.

In terms of the telnet protocol, T* does not implement the telnet protocol at all.
Yes, it doesn't really need it, does it. I started with some example telnet server code, and spent more time removing telnet features than if I'd started from scratch :D

Good answer, Mark. Just to add that cheap SCART/HDMI converters are not a magic bullet either.

How would 3D printing fare with the beeb texture? I know it’s a bit of a tricky texture, from my attempts to clean deep-seated gunk out of it.
