I had a Spectrum that was missing a resistor. It all worked fine until something was plugged into the edge connector then the keyboard went funny! QC indeed.

Nothing wrong with that. My components always look like that after I solder them on. :evil:

Was it a Dundee built 16k or 48k? The QC at Timex was non existent.

Wow! The whole main pcb is tilted! It’s a wonder they got that one chip straight!

I don't know what you're complaining about, it's hard for the workers to get everything straight and true whilst the whole factory in Wales is being shook by the the 5.4 magnitude earthquake (that occurred on 19th of July 1984) :mrgreen:

The trouble is, how to tell where it was made?

Board revision usually helps. For example revision 4S is made my Samsung in South Korea. Earlier revisions are guaranteed to be Timex.

Dundee. Numerous stories about that place. Very bad industrial relations coupled with the fact every pub in the city had a bloke who could get you a Spectrum for 20 quid.

Issue two. See if you can spot the missing resistor!

It's not missing, it's just an optional extra!
And yes, an issue two would have been made by Timex...

I had (or maybe still have) a Model B that spent 25 years with a bent pin under the socket for the 8271. It had spent its life as an Econet workstation, so it was never discovered until about 2008 when I tried upgrading it with the disc interface chips from a dead machine and it didn't work. I think I ended up bodging it with a blob of solder or a link wire.

Issue 2 will be Timex.

When Amstrad moved all manufacturing for the Spectrum to the Far East with Orion (who did the CPC, PCW and would be doing the soon to be launched PC's), Sugar threw the Timex factory the bone of assembling his DMP2000 printers. Hence this lovely picture.

By the way, do you know who Amstrad used to assemble the U.K. made versions of the ZX Spectrum+2 (the grey coloured machine, not the later black version)?

Timex did a final run of 48k machines to use all the components up in the UK supply chain but I am wondering if they ran short on the old style cases they may have also made some +2's as well. I know there are 128k toast racks knocking around with Amstrad IC's in them for example. Amstrad wouldn't tolerate waste so I imagine any way to clear up the tangle of components in the supply chain would have been used.

The thing we do know is the entire situation was a mess with components scattered across the UK in huge numbers. All these people were Sinclair creditors so Sugar said he would take care of all of them and then get Timex to assemble them. All the 48k's made got sold to Dixons at pretty much cost so that the shelves were clear for the launch of the +2.
