Rare Fujitsu 128K Bubble Memory Cartridge, measuring 1.75″ x 2.25″ x .75″, with the label printed, "FBM-C128GK," annotated below, "10/07/87." The top is labeled in English and Japanese. Includes its original plastic case with bilingual storage instructions. In fine condition. The consignor notes that this was purchased as part of a set in the late 1980s, and one of the other cartridges had a slip of paper inside that read "80 Bubcom System." The Bubcom 80 was a business computer made in Japan by a company called System Formulat, Inc., in the early 80s, before the design was purchased by Fujitsu and marketed under their own name. Little is known about the rare system.
