The IBM JX (or JXPC) was a personal computer released in 1984 into the Japanese, Australian and New Zealand markets. Designed in Japan, it was based on the technology of the IBM PCjr and was designated the IBM 5511. It was targeted in the Australasian market towards the public education sector rather than at consumers, and was sold in three levels: JX (64 KiB), JX2 (128 KiB) and JX3 (256 KiB). Upgrades were available to both 384 KiB and 512 KiB. The JX was the first IBM PC to use 3.5" floppy drives.[3]

IBM Japan expected to sell 200,000 units of JX, but only 40,000 units were produced. The JX was discontinued in 1987, and IBM Japan gave 15,000 units of JX to its employees in honor of the company's 50th anniversary.[2]
