[Epictronics] happens to have a rather special machine in his possession. It’s a rare IBM PC prototype or concept machine from the late 1980s known as the IBM 7496 Executive Workstation. It’s a striking thing, with a rather enticing case design that has the monitor permanently attached on a nifty swivel mount. Only… the machine wasn’t working, so some repairs were in order!

Running a machine off floppies alone is as frustrating today as it was back then, so [Epictronics] goes further by adding in an XT-IDE card to allow the machine to interface with a hard drive. An AdLib clone soundcard…
