Building a New ZX Spectrum 48K #VintageComputing #RetroComputing

shred.zone documents the making of a modern replica of the British ZX Spectrum 8-bit computer. A non-repairable motherboard donated the ULA, CPU, LM1889N, the coil, and the RAM chips.

The new replica motherboard is made by PABB and can be ordered from PCBWay.

For the required components, I assembled a bill of materials. It contains as many new components as I could find, but some rare parts are long out of production. They can still be found as NOS parts at online marketplaces, or they can be replaced with replacement types or replicas (like the Retroleum Nebula or vRetro vLA82).

I bought the original board without any case. But luckily, there are replica cases, keymats, membranes, and faceplates on the market, so I could assemble a brand new outerior. Of course, I chose a transparent case, so the nice black mainboard could be seen from the outside. Well, at least a bit.

And there it is, an (almost) new ZX Spectrum in mint condition.

See the details in the post here.
