IMSAI I-series (IMSAI 8080) Cabinets

The I-series cabinet is the iconic “IMSAI 8080” design by Joe Killian. There were essentially two versions of the cabinet. The first one used a few PEM nuts and mostly #6×¼" sheet metal screws. The I-series cabinet is based on the later original versions with all PEM nuts. By late 1976, all shipping IMSAI 8080 cabinets were these versions.

The I-series cabinet kit comes in 8 sheet metal pieces and can be assembled by just about anyone with a #2 Phillips screwdriver in less than an hour. It comes with a finger guard for the fan cutout, a power entry module, and eight rubber feet to support the heaviest power supplies. It also comes with a printed User Manual that may be transferred to a binder.

We have made a few improvements over Joe’s original design, most of which were enabled by newer technologies and standards.

Replacing the wrinkle finish paint with a very durable textured powder coat finish.
Adding a C14-standard power entry port to accept power cords from any country. Of course, the original captive gray 8 foot long NEMA-15 power cord is available as an option.
Replacing four of the DB-25 back frame cutouts with six DE-9 cutouts.
Adding a new set of card frame mounting holes in the front and back frames to allow the card cage to be raised slightly to better handle IEEE 696-standard cards.

The new power entry port is compatible with any IEC C13 electronic equipment power cord. Unless you order the captive US (NEMA-15P) power cord, your cabinet kit does not come with a power cord. Many of our customers have drawers full of extra power cords. Even if this is not the case for you, there are too many options for us to keep stocked based on your country and personal preferences. Many local electronics stores sell power cords. If that is not an option for you, we suggest you go to McMaster-Carr and choose one for your country.

The I-series cabinet is available without the blue table top cover.

The I-series cabinet is expected to be available by April of 2025.
