7546 Overview

7546 Overview (photos from ebay seller pcheaven201)

The 7546 Industrial Computer uses a modified Model 56/76 chassis. The front portion was extended to accommodate the front fan w/ filter and the lockable drive door.

Front view - very utilitarian. Removable fan filter, lockable drive doors.

Side view

External drive bays - possibly reused from Models 35/56/76?

Power switch area - combined P/N and S/N?

Back side view - clearly based on the Models 57/77

View of the planar I/O area - matches Models 56/57

Note: The I/O breakout box visible on the last two photos is a 3rd-party accessory.
