Re: Palettemate / enhanced video ULA with 4096 colours

Checked for shorts visual via mag and multimeter when I did it. Nothing obvious. Everything else appears to be fine, just the other periphals don't post messages, but they work fine, the main bbc one posts messages. Possibly a bad joint I suppose. So you still do the control break for gosdc, you jus...

Re: Palettemate / enhanced video ULA with 4096 colours

Pin 37 on the 6522 is definitely A1 so the documentation is correct, but that screenshot looks more like it is hooked up to the 6845, can't tell exactly because keyboard obscures it.

Anyway socket now soldered in, so that it hopefully the hardbit done

Re: Palettemate / enhanced video ULA with 4096 colours

In the picture of the probe on the master (in the manual) it looks like it is going to ic22 which is the 6845. Pin 37 is ra1 (which is not the same as a1). But manual says ic6 to pin 37 a1. Confused.

Re: Upgrading a BBC Master power supply with a modern 60W supply

It's possible to simply follow the openscad design and cut the brackets by hand, but 3D printing is easier :) There are a number of on-line services that can take the 3D printer files and make you brackets - most of the big 3D printing websites offer that sort of service. There's a chap on the Face...

Most Beebs produce noises from their loudspeakers.

It is probably the speaker but being high pitch the directionailty is quite hard to pin point.

Sounds about right. I will probably take 2 if it will fit in the 2015 ATOM remake, along as I dont have an 2015 Atom PCB and one would neeed o manufactured then I guess we could perhaps tweak the pcb layout to make it fit.
