Eu de certeza que prefiro o possivel ruído que um ZX spectrum possa fazer do que qualquer modem broad band power line.<br><br>O ZX spectrum foi muito usado durante anos e anos e desconheço se alguém se queixou de ruídos em toda a banda.<br>
<br>Alguém terá por aí algum a funcionar?? Caso alguém tenha algum mas que precise de um CPU ZILOG Z80 diga.<br><br>73 de Hugo Barata CT2HMX <br><br><div class="gmail_quote">On Thu, Dec 13, 2012 at 7:00 PM, Pedro Ribeiro <span dir="ltr"><<a href="mailto:ct7abp@gmail.com" target="_blank">ct7abp@gmail.com</a>></span> wrote:<br>

well an antiquated ZX Spectrum would hold up to modern EMC
requirements</a>. 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?'"<br>

Comentário pessoal: O espectro abaixo de VHF é de tal forma
desconsiderado actualmente que o autor dos testes só os realizou
entre 30MHz e 1GHz, pessoalmente acho que a analise junto à
frequência do relógio base e suas harmónicas continha certamente uns
picos mais interessantes...<br>
Mas ...<br>
Será que bate um PLC dos "bons" ????<br>
