Something like one of these: Vastly more efficient and no heat production to speak of, which means less thermal stress.
Sir Clive Sinclair launched the first affordable consumer computer in 1980, costing less than £. His daughter Belinda Sinclair told the Guardian that the pocket calculator trailblazer and the brains behind the Spectrum home computer died Thursday morning at her home in London. You may also want to consider replacing the linear regulator with a drop-in buck regulator. Home computing pioneer Sir Clive Sinclair has died at the age of 81. This will cause the expensive SRAM chips to release their magic smoke, so you probably want to recap it. Every item is carefully tested and checked to ensure it still loads (even after all these years). Re the power supply: it'll probably settle down to a more reasonable voltage with a bit of load.Īlso, the capacitors in Spectra are notoriously terrible, and one of the failure modes of capacitor failure is the negative power rail dying. A classic title from the ZX Spectrum archive. Luckily they're easy to replace and you can get new ones for cheap. Sinclair then moved into the production of home computers in 1980 with Sinclair Research Ltd, producing the Sinclair ZX80 (the UK's first mass-market home computer for less than 100), and in the early 1980s, the ZX81, ZX Spectrum and the Sinclair QL. Yeah, those keyboard membranes turn into brittle dead leaves after a measly three or four decades.
