The E0227-702-008 is a memory board product under the Opus 5000 line, produced by Okuma. This component, known as a bubble memory card, is a vintage non-volatile, solid-state memory device originally introduced in 1967. It utilizes a thin magnetic film holding multiple small magnetized areas, or 'bubbles', with each bubble storing one data bit. Though once in high demand, its popularity diminished in the 1980s due to the surge of hard disk computer storage. The product, now out of production, hosts a variety of internal components including orthogonal coils and a bubble chip within its dual magnetic plate exterior. Its dimensions are 6 x 11 x 1 inches, weighing in at 1 lb. Despite its outdated technology, it remains an integral part of legacy computer systems.
