A model A. Not working but probably a simple fix judging by the description?

Quite a big gap at the back - does that make it an early-ish one?

Also an instant music setup!

The presence of an aperture for a rear reset button makes it an Issue 1, doesn't it? I'm not sure I'm seeing an auxiliary power connector, so an early PSU as well?

That looks really desirable; which could lead to a pretty ugly bidding war...

Issue 2s and early issue 3s also had the big gap and reset button hole (never seen a button actually fitted to one though...). Shame can't see the pcb...

This A doesn't seem to have any ports fitted which is nice to see as most have been upgraded to B spec with at least disc drive, analogue and printer ports added. So that alone will raise interest in sure...

Don't know about the simple fix, the smoke part yes maybe but he said both LED's stay on which is not a good sign, as normally even if the capacitors are smoking the BBC starts up without a problem, it could be because of the electrolytic capacitor that also needs to be changed in the PSU.
Good luck and hope you win and are able to get it up and running [-o<

mmm looks like its a BBC keyboard only, as some company's came out with a different box to put your BBC and drives into and then had the keyboard lose from the BBC itself, so I would not pay too much for it as I don't see the BBC in any of the photos only a keyboard.
The monitor is a mono display and the printer a old dot matrix printer.

Just a keyboard in a 'posh' case. The monitor and printer may not be working. The printer is an Epson clone. It is at its money now at £20. :?

Why do I keep collecting Acorn gear? I'm going to need a considerably bigger man-cave. :?

Thanks folks. I had no intention of bidding on it - that’s the ugliest “Beeb” I’ve ever seen. :lol:

Not Acorn/Beeb, but I'm quite tempted by this rather nice looking IBM PS/2, despite having no need for it, nowhere to put it and it being on the other side of the country (400 mile round trip):

Yes... :D

The trouble is, there are to many nice/beautiful things in this world I wish to collect, but why keeping it all knowing I'm never gonna use it, let some else have it to have much fun/joy... :D

That can be a hard decision to make!

I bought an unbuilt ZX81 kit a year ago with a view to building it. I still have not done so (unbuilt ones are pretty rare) and am rapidly coming to the conclusion that if I am not going to build it maybe I should sell it on for somebody else to do so.

@LB - It takes less than an hour to build a ZX81 from a kit, then the value is gone. Maybe you should frame the case and components and hang them on a wall?

I'm not joking...

Thats the argument I keep having with myself. But then it seems a shame if it is never used as a computer.

But then unbuilt kits are so rare...

Ask yourself why you collect computers. To play or preserve? Then you'll know the answer to the "build it or not" question. If it was me I'd buy a built ZX81 to play with and keep the kit as is.

One or two! I decided to build my own anyway. I got an incomplete one from eBay, desoldered it to the PCB and bought all new components (except for a new old stock ULA and the original ROM) and put it all together. It didn’t work but this turned out to be due to the 6.5 MHz resonator. By the time I found this out a house move rudely interrupted proceedings so I have got no furthet yet. Once I find a working one of these (and move house) I can finish off. And then decide what to do with the kit. :?:

I guess different people get fun out of retro computers in different ways. We have the Collectors who enjoy getting rare hardware and keep it for keep’s sake. And we gave the Hobbyists who like to play with old computers. For the Hobbyists the state of the computer is less relevant.

I guess you are not a Collector so an unbuilt ZX81 is really not for you. Why not sell it on to a Collector who values items like that?

Title says A310 pcb, but it's an A305 as half the memory is socketted and not populated.

Seems to be mssing MEMC, VIDC and (strangely) the 9 pin RGB out socket, so needs some work, but could be interesting for someone.

Nope, it went over my bid...

Reviewing the pictures and the problems listed by the seller, I can say that it has a SMPSU.
