This reminds me. I have a customer who runs a pipe bender at his factory using a 386sx I built for him about 12 years ago. The components were already old by then.The 386 runs on dos, also about a R80K upgrade to get it on windows.
Does very simple stuff and I don't see the point in doing an upgrade when it works fine.
I still have my Cambridge PCWorks FourPointSurround which was produced in 1998. I have three sets. Two originals and the later Desktop Theatre 5.1. Then Creative came into play.I have a pair of Mecer SP-689 speakers bought new in mid 1998, they still sound amazing, despite 21 years of use.
