Product group of magnetic bubble memory and BUBCOM80

A magnetic bubble memory is a type of an electrically writable solid-state non-volatile memory that uses a magnetic bubble technology. This technology was invented by Bobeck and his team at Bell Labs in 1967. Magnetic bubble memory is readable and writable electrically. Because of these advantages, it was first used as a program memory of 10 or 100K bytes. After that, it was used as a "Mini file (10 to 100 K bytes)" or a "File memory (100K to 1M bytes or more)" from 1978 for 10 years.

The bubble Memory mounted on a circuit board was used as a price-file memory on a POS terminal because of its non-volatility. A bubble cassette, in which magnetic bubble memory is packed, was used as a high-speed removable memory for personal computers like FUJITSU MICRO8, word processors, and NC machines.

The certified products are circuit boards on which magnetic bubble memories are mounted, bubble cassettes, documentation for a production process, and BUBCOM80 which is a personal computer mounting a bubble cassette interface assembled by Fujitsu Limited, designed and shipped on the market in 1981 from Systems Formulate Co. Ltd.
