About this machine: The VAXstation line from Digital Equipment Corporation was an attempt to miniaturize the VAX in to a smaller form-factor that could be used as a desktop workstation rather than the mainframe configuration of previous models. This particular VAXstation has a graphics card (hence the SPX designation), allowing it to be used like a conventional computer. It's fully functional, and still has an original copy of VAX/VMS from the 1990s.
