Those do not have PCB pins Bruno, they're "solder bucket" - the holes you'll need to mount them will be huge. -

BTW it would be really nice to scan both sides of the PCB. There are some people (including me ;-)) interested in the schematic of this device. Looking at your shots i see it will be extremely easy to draw if we get such scans (or highres shots). -

It's plenty warm enough, trust me!
Call that neat? Where's the custom PCB, where's the sweat, anguish and dissapointment? Where's the love, the art, skill and craftmenship?
Oh, ok, I 'spose it's ok.....

I think that quality piece of work has raised the game somewhat. Puny soldering - hah! We need custom PCB's for our beloved spectrums and we need them now! :-D -

Well, what is done is done. I scanned all my custom pcb cartridges and eproms (pics will be posted soon). I still haven't figured out how to control focus when using a digital cam. :lol: And the scanner seemed like a good option. :) -

Hey, a Spectrum powered CNC machine :-)
I'd love something to make PCB making quicker and easier. Something that'd automatically drill the holes would be really useful for larger boards. -
