Submission + - Sinclair ZX Spectrum FAILS latest radio noise rules SHOCK (theregister.co.uk)
wisewellies writes: Ben clearly has way too much spare time on his hands, but he decided to see just how well an antiquated ZX Spectrum would hold up to modern EMC requirements. His blog is a good read if you're looking for something to do while pretending to work!
From the blog: 'This year is the 30th anniversary of one of my favourite inventions of all time, the Sinclair ZX Spectrum. A few weeks ago, I finally bought one: a non-working one on eBay that I nursed back to health. Fortunately there was very little wrong with it. Unfortunately it’s a 16K model, and a fairly early one at that, which won’t run much software in its native state. This probably accounts for its unusually pristine condition.
We took half an hour in the chamber to perform an approximate series of EN55022 measurements, to check its radiated emissions against today’s standard. The question is, what have we learned as an industry since 1982? Does a 30-year-old computer, that embodies Sinclair’s mastery of cost-engineering and elegant design like nothing else, pass modern legislation that would render it saleable?'
