ZX Spectrum 128k+3 before restoration.Īfter checking that the output voltages on the PSU were as expected, a quick power-on test plugged into the RGB port revealed that the computer seemed to boot up fine. The computer arrived safely, and appeared to be in original condition except for the addition of a phono jack sticking out the rear case, which I assume was used as a composite video output. The ZX Spectrum 128k+3 was one of the later machines produced by Sinclair, and was the first Sinclair computer that was completely designed by Amstrad – it was very similar to the ZX Spectrum 128k+2A, but featured a 3″ FDD instead of a tape deck. ![]() I’ve owned several different Sinclair ZX Spectrum computers over the past couple of years, but I hadn’t got my hands on a 128k+3 at this point, so I set about looking to get one for my collection – eventually, a machine in good, boxed, but untested condition with peripherals popped up on eBay, and I managed to win it for a reasonable price.
