A gentle hint - use "Wanted: <name of item>" as a title for wanted posts
That way people like me who don't have a ColourCard Gold don't need to read your post only to find out that they can't help...

Come on, admit it was exciting

The BBC Microcomputer ones were earlier. BBC was trademarked in the US so later ones which were also to be used on ones shipped overseas used the spelled out version.

Single 360k drive. Almost all but the very first PC drives were double sided 40 track.

Just a wee bump as there's still one of these available

This thread is what you need viewtopic.php?p=257800#p257800

That little metal bar should ping up and release the cable?

Don't leave the vinegar sitting there too long. If you're in a soft water area, tap water should be fine. Water from the water butt... I'm not sure? Depends on what's in it? Probably? If it's clean? :S You don't need to worry about IPA, just put it somewhere warm to dry. edit: As to the differences,...

Does it need to be an A3000? Would one of the ARM250 machines (i.e. A3010/A3020) work too?

The only variable capacitor on the board looks to be over on the left near the modulator on the issue 6? Disk shaped thing with a little screw in the top?
(I'm going by pictures on the web here)

I'm fairly convinced this isn't the ULA. It really needs to be hooked up to a scope. It'll be something in that video circuit

The only source of a ula is another Electron. Sometimes Dave Hitchins has spares. Have you tried tweaking VC1? It's part of the video timing circuit...

and even buying name brand is no guarantee - how many fake Hakko units have been sold that look like the genuine thing. Just look at the youtube videos by bigclivedotcom (and others) - potential death seems to be quite the feature of some of the Chinese kit. I must also look at getting a new solder...

Sorry...hijacking this a bit. I've also been looking at desoldering stations, for SMD work, and found a Duratool D01841 at CPC. The only annoyance is that I need to buy the PLCC chip (is that the correct term for ICs with pins all round the outside?) nozzles separately. You don't necessarily need t...

I've got the Hakko and the Duratool desolderer. Both are excellent.

it's also incumbent on forum users to think about how they might be coming across. I'm afraid that is, in effect, excluding from the forum anybody on the 'autistic spectrum', who often find that difficult or impossible. c.f. comment about not wishing to get into discussions here. No one is being ex...

We can be contacted by PM as usual. We don't tend to reply at 2am. Apologies. I should say, for the record, that no one was ever specifically accused of being a reseller. I've addressed this in the thread, and by PM, but will also address it here. I'll leave the thread open for other moderators/admi...

Right. I hold my hand up here and admit I overstepped the mark, this should have been dealt with by PM. I'll remove the offending posts. For the record: No PMs are ever stopped or deleted on this forum. We can't see what's sent, we have no idea who's talking to who. Administrating sales is a pain. I...

I think getting it along to abug would be the optimum solution here

d.

Oh, goodness no. The banked thing wasn't a standard feature of the RAM on the coprocessors that were available at the time.

Hi Mel - I sent you a PM, you can reply to them now. Obviously Mel is keen that this gear all goes to a user, and not someone who's going to resell everything. I'm not down in that neck of the woods myself so can't pick up to pass on as appropriate. I'll try and poke at some people who might be down...

The version in MOS3.5 is probably the final version. (B3.30)? Unless a later version was supplied on the welcome disc with the Master Compact? I'm fairly sure the version in MOS3.5 will copy itself over the tube and run as Hi-View. I don't know if the version in 3.2 does? There was a Hi version of v...

That's pretty much ARM3 performance minus the the cache. Speedy!

As in the forum rules, trades are at the risk of those involved. We don't ask people to declare interest in the thread (however, I would argue that it's always a good idea to). There's no contract until money changes hands, no seller is under any obligation to sell to anyone. No one is owed anything...

I have to say, playing devil's advocate, this does all beg the question.... "Why would you want to?" in the context of the next?

It was never released for the electron on disk. Unless anyone's hacked it, I doubt it

d.

It does. It can see all the slots as MOS 3.2 can.

d.

Was there ever a US version of the Electron ROM? I don't think there was

If the elk is booting then it's either ULA or something related or something around the video timing. https://www.4corn.co.uk/archive/diagrams/105,000-C%20Circuit%20Diagram%20For%20Electron%20Microcomputer%20Main%20PCB.jpg I'd check LK2 and what the deal is with IC11? If you have a scope you can at ...

As far as I'm aware this has actually been bought (not by me!), but hopefully Andy will confirm when he pops up
