Thanks people for sharing this amazing project. I have routed a couple of boards for this project, being one for use with a box by Hammond, reference 1455C801 and AAA cells but can also be used standalone as it has mounting holes. I have used stereo jacks for input/output as such parts are very easy to find. The layout was drawn from scratch but the circuit was compared with the original several times.
Full sources are included (Eagle 6 and above) in the zip as well as a PDF with schematics, 1:1 view of the board and the components placement map with both values and references.
I hope you all enjoy and please whoever built it post the pictures here.

Best Regards
Danjovic

That looks awesome Danjovic.

Lardo Boffin, do you have your prototype unit back yet? Have you had a chance to turn it loose on those tapes you can't get to load normally?

I am going to see if I can make a PCB for the people in the States before anyone else gets further on this...

Shipping is cheaper on the continent.

The components density on the board is quite low so, most probably a smallest PCB can be done and installed into the ZX81 case, and the voltage taken from the ZX81 itself that will avoid the batteries use.

When I get my ZX8 repaired I'll investigate about this...

That's a cool idea, but I'm not sure I'd want it inside the case. I use mine as a "sometimes" device for direct dubbing one tape to another, and the rescue of the odd tape that "just won't load". It might be possible to cram it in there; I'm just not sure it's worth the trouble.

Any luck with the PCB gammaray?
