There's also a photo of an issue 1 pcb with the same style printed serial number in the PCW magazine review from Jan 82. It was #10, and (probably coincidence) also missing the video-out BNC connector, as was the one on eBay.

That issue one is very interesting - love the hand written serial number.

Just noticed that the keyboard circuit on that Issue 1 photo from the magazine is totally different to issue 2 keyboards. Apart from the speaker - the circuit seems to be on the upper side as you can see green and very distinct upper side copper tracings. Makes me think that they decided to transfer the circuit to lower side on later designs.

Totally different from issue 2/3 single sided keyboard circuit (which I believe are similar to issue 4/7 except the speaker's glued on and has no speaker mounting holes).

Anyone have any ideas about the issue 1 keyboard?

Got this machine this week...

I have another 3 very similar but they missing serials on the outside. Will open them up and have a look to see if they have internal numbers.

07-ALA-01 - 000333 - Not sure how significant the 07 is?

Have a close look at the expansion connector :shock: it looks quit pitted, which may indicate poor storage!

Looks like it has been stored somewhere damp, looking at the cassette, RGB, composite video and Modulator connectors on the side.
