Did even Watford ever sell dual disc drives, in which the two drives were so blatantly mismatched?

To play Devil's Advocate, might one have been replaced some time later when the unit was taken back for repair?

Oh dear.
That's a neat job compared to a Beeb I acquired some years ago where there is a ZX PSU mounted on top to supply the fan...!

LoL, that's my point, if you look under the cutting board there appears to be a antistatic mat with a bonding lead running off it but then they make it pointless by putting a cutting board between it and the circuit board...

He seems to have a lot of equipment. Maybe he is using the cutting board as a background for the pictures?

Anyway, I suppose it's good that there are people working to repair retro computers. Good value - who knows? Depends on the owner's willingness to pay.

Cutting boards make good mouse mats. Maybe he has a really big mouse.

This one caught my attention as a professionally reconditioned UK101 with no warranty or returns. :shock:

https://www.ebay.co.uk/itm/ULTRA-RARE-V ... Swgsddzrcy

I love the red Shift-Lock key (If one cannibalises a BBC keyboard, why not use a Shift-Lock key cap? :? ) and the unknown expansion board (which is probably the video modification to add an extra 1K to the VDU RAM) though I would have expected the 8T28 ICs to be present and the sockets on the back to be properly connected to fully enjoy the epithet 'professionally reconditioned'. Do the cassette interface and the video output both work?

The original PSU was always flaky and ran very hot and, with 8K RAM, could cook the motherboard. Removing the 5v regulator to a decently sized heat sink was one of the first things one did after owning the machine BITD. Nowadays one could use a Meanwell 5v 5A PSU module and remove the old mains transformer and linear regulator so making the machine run a lot cooler.

The case is not original. The UK101 did not come with a case. The one shown is an after market case which sold for £29.99 BITD. It is still a nice case, though.

I can’t help but notice this seller never actually says what he does to professionally refurbish his computers to a very high standard.

Seller is irrelevant. It is the description that intrigues.

I'm not sure if this is LOLPRICE, LOLDESCRIPTION or both.

https://www.ebay.co.uk/itm/Retro-Britis ... SwKiRe0YoK
£285 Buy it Now
Condition: Parts Only

Acorn RISC PC 600
In nice cosmetic condition.

There does not appear to be any evidence of CMOS battery leakage (see photos). The battery was removed and replaced with an off-board battery some time ago.

This replacement battery does now seem to have lost it's charge though so you have to hold down DELETE while booting to start up the machine.

Once started it runs stable and as expected.

The front flap still works and has the spring fitted.

ARM 610 Processor
16MB RAM
1MB VRAM
RISC OS 3.50
3.5" Floppy DD
Hard disk

The monitor, mouse and keyboard used for testing are NOT included.

The case clips are missing but this doesn't affect anything. Because of this and the need to hold down delete while booting I have listed as spares or repair.
If you take a look at the photos... the top lid has had a very hard whack on the rear left corner, which has sheared the plastic where the rear locking clip would go. This is largely cosmetic and something I could overlook...

If you look closer, it's got a 16-bit sound upgrade fitted, which makes it an Mk.I or Mk.II board (Medusa). Look closer still, it's an 0197,100, making it a Mk.II Medusa.

But what gets me is this photo:

I wouldn't call that pile of green mush "no signs of battery damage". And frankly the soldering on that external battery wiring is (at best) shambolic.

This leaves what I assume is the backup battery itself...
s-l500.jpg
But what is that battery? "GOO"... "1S 3.7V 720mAh 25C Va22"... wait, it can't be...
BatteryPackScreen.png
It is. It's a single-cell 3.7V LiPo pouch cell for a radio-controlled drone.
This thing is hooked up to the battery terminals with no charge controller or battery protection to speak of.

This is giving me awful memories of the stories of first-gen lithium-endowed BBC Masters going up in flames...

Own opinion only: that's an easy win for the worst "restored" RISC PC I've ever seen. I'd love to take it and give it the TLC and spare parts it deserves (rendering my parts-mule RISC PC ever more decrepit in the process), but not at that price.
