Just like any other 30-year old electronics, you should expect that such a computer will require repair and maintenance by an expert. Perhaps more so, since as a workstation made for professionals, it assumes the presence of a professional system administrator to configure it, quite unlike a "PC".

I'm curious why you bought a voltage converter. Was the stamping indicating worldwide voltage compatibility (100–120/220–240) next to the power socket not easily visible?
