Re: Done scratching that itch

I don't know if you've used KiCAD, but its default 3D rendering of PCBs boasts a shocking pink soldermask with a pale blue silkscreen. I was rather disappointed when I realised that nowhere affordable makes boards like that.

That violet mask is the closest thing I've seen to KiCAD's fantasies.

Hello mate.

Everyone's at ABUG this weekend, so the usual flood of welcoming messages may be somewhat tempered.

Beeb ULA / 8271 decaps?

Have there ever been any attempts to take high res die shots of the Beeb ULAs, or the 8271 for that matter?

Anyone know?

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

Alex van Someren mentioned in his talk at ABUG on Saturday that the Beeb was indeed first designed to use 8" drives (and rightly or wrongly I inferred that the original intent was exclusively for 8" drives, although this obviously ended up not transpiring). Of course this doesn't answer the question...

Re: STH Elite disc image

But at least Repton ( the version here? https://www.stairwaytohell.com/bbc/archive/diskimages/Superior/Repton.zip ) is undersized and can be padded out if necessary. The fact that the SSD says it's an 80 track disc can largely be ignored. Whoops, you're right. Well, that's curious; my code rejected...

STH Elite disc image

During testing on the Disc Toaster I encountered this Elite image from the Stairway archive: http://www.stairwaytohell.com/bbc/archive/diskimages/Acornsoft/Elite.zip Downloading and extracting it yields an SSD file of 115456 bytes. The maximum size for a standard-formatted 40 track disc is 256 bytes...

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

The Model B circuit diagram contains an extra clue, as it labels one logical output to the disc drives the "LOAD HEAD" signal. "Loading heads" was apparently a process only relevant to 8 inch drives. 5¼ inch drives don't have any such mechanism; this signal is usually used instead to switch the spin...

It’s not normal to repeatedly press break in quick succession.
Wasn't pressing BREAK twice quickly the pre-OS-1.2 edition of Ctrl-BREAK?

Maybe Colday was remembering this behaviour from a pre-OS-1.2 machine.
