This is the very rare Sinclair ZX Spectrum 48K Issue 4A version with a distinctive yellow PCB and blue lettering. This is a great looking Spectrum, nice case with minor marks but the inside is lovely and deserves to be mounted in a transparent Spectrum case! The circuit board has all the RAM chips seated on the motherboard rather than having some in sockets. The original bright blue capacitors are still present to preserve it's authenticity.

I've completed a composite mod (which can be easily reversed) so it will run on AV/composite input on the TV. It's not been recapped. This is fully functioning and I've run a few games on it to test it. (see good ol' Jetpac in the photo 😊 ).

Although I am featuring just the ZX Spectrum unit, I do have a few refurbished ZX power supply units and if you want one posted for free, please send me a message once you have bought this item and I'll ship one along with the ZX Spectrum.

Don't miss out on owning one of these rare versions of the Sinclair ZX Spectrum!

This vintage desktop computer belongs to the Sinclair ZX Spectrum 16K/48K model, known for its iconic design and lack of a built-in monitor. Perfect for retro computing enthusiasts, this working computer offers a glimpse into the early days of personal computing.
