Re: Hello - Acorn hardware find

Great find! The Master will almost certainly work, but the battery used to store its settings will be flat and so initially it will look like its not working. Hold R during power up to reset the settings. The other two machines have PCB mounted batteries and so are at risk of corrosion. Even this is...

Unpredictable website issues on ancient hardware

This is totally off topic, but I'm posting on here because I know the readership is very well informed and helpful. It's very much not a criticism of the Stardot website, but Stardot is good example of the kind of website that is affected by the problem I'm experiencing. So... I have a very old Andr...

Re: A310 floppy drive alternatives

Same here. The thing about alignment though is that there's no way to adjust it, and also you'd think the drive would be able to read discs that it had formatted itself, even if misaligned. So this leads me back to the simple "not close enough" theory. I don't really know what I'm talking ...

Re: A310 floppy drive alternatives

This is like a self-help group, it's excellent! Would I be right in thinking that the copper-coloured spring plate simply holds the head down against the disc, and (within reason) doesn't need to be too precise provided that the head is actually kept in contact? If that's the case, is it possible to...

Re: A310 floppy drive alternatives

I’m in the same position myself, but similarly haven’t found an alternative. The real drives are very rare and so, it seems, is much documentation. It’s surprising how difficult it is to find old floppy drives.

Re: BBC B (Viglen) with very strange keyboard-related issues

Switching keyboards was very easy... in fact I realised I could use the Viglen's stretchy umbilical and not even remove the keyboard from the other BBC. With alternative keyboard - problem goes away. With original keyboard... er... problem remains "gone away". This is going to be annoying!...

Yes I do, so I'll try that. I wasn't sure if the keyboard was necessarily relevant at all, but that would be a great way to rule it out. Also IC32 sounds worth investigating as well! I'm sure this is fixable, it's just a surprising last-minute problem (which of course only appeared after I'd screwed...

BBC B (Viglen) with very strange keyboard-related issues

I have recently repaired a Viglen BBC B, which had a couple of fairly straightforward faults: - System VIA was dead (new one fitted) - 2 DRAM chips dead - ATPL Sidewise board needed re-seating. Having done all this, the machine seemed to work fine, and I thought it was finished. However, on testing ...

Re: Hello from East Kilbride

Welcome!

I managed to recreate the E2P a few years ago, and its original creator John Wike joined this forum and made some amazing improvements to it. He also recreated the PMS product Hi Wordwise Plus, which appeared to be lost - so if you have a real copy of that, it would be really interesting.

Re: Acorn Electron Sound Expansion Cartridge re-created

That’s great, very impressive! Part of my motivation for recreating this was to see if the sound quality and/or the firmware were really as bad as some reviewers had said. I think we can now officially put those fears to rest. 🙂 It’s a pity the original designer, Mr Ingleby-Oddy hasn’t stopped by yet.

That looks great! The funny thing is, I don't have much recollection of it being that bad. The main thing that stood out to me about Electron Meteors was the way it wasn't in colour (like the BBC version) or with a blue background (like on the box)!

It will work as a line on its own. The only requirement is that it has to be after the mode change, as MODE always turns the cursor back on.
