NorthStar Horizon Case Cover Replacements

Orientation of the drive with respect to the power transformer on the Integrand was important. Changing the position by 90 degrees offered a substantial improvement, but that wasn't an option, as the panel was delivered pre-cut for a drive.

In the case of the Durango, the monitor was a small 9" Ball Brothers OEM model and the drives were Micropolis 100 TPI models. The large carriage stepper motor on the integrated printer was less than an inch away from the B: drive. Another reason to shield things. Most "PC" boxes from the 1970's had some sort of basic design problem; EMI radition being only one of them (Did the Horizon pass VDE certification?). Most couldn't withstand a hipot attack; very few could survive a thermal stress or shake table session without having a component with "flying leads" dismount, or having cards pop out of the backplane connectors.
