Reusing the Obsolete

As you, folks know I am ardent supporter of re-cycling and will encourage all and one, helping the cause of avoiding techno-trash. Many broken electronic items/systems can be fixed just with a replacement of a one or two components but with Moore's law still going strong even after thirty years, it hard to source most of these components, as they are declared obsolete within just a year or two.
Internet shopping is changing all this, as you are now able to finds these Obsolete Semiconductors rather easily.You can find all kind of obsolete devises like Diodes, ICs, distributors, relays, flash memories and all other stuff on websites like 4starelectronics.With their obsolete part search utility, you can search a database of more than 15000000 new, obsolete and discontinued components.
Many of the legacy systems are still operational due to some diligent efforts from dedicated hardware engineers, who take every effort to keep them running and my Hats off! to them. The only concern regarding these components sourced through Internet is about their functionality but give their low price tag, it is risk worth taking. So next time some system is down around you, suggest the possibility of fixing it.
