Panafacom MN1610

Panafacom (currently PFU) was a conglomerate of the Japanese companies—formed by Fujitsu, Fuji Electric and the Matsushita Group on July 2, 1973. They developed one of the first commercially available 16-bit microprocessors, the MN1610.[1][2][3]

The PANAFACOM Lkit-16 was a learning kit released in March 1977 to popularize Japan's first 16-bit single-chip microcomputer. The microcomputer was equipped with the nation's first 16-bit parallel high-performance single-chip processor (*1), developed by PANAFACOM in 1975.

This processor provided better cost performance than conventional 8-bit microcomputers with its enhanced speed (about 200%) and reduced memory usage (about 60%). The unique features of the Lkit-16 were: (1) a simplified keyboard for assembler input, (2) console functions that allowed easy debugging, and (3) a built-in audio cassette interface for data I/O. Through a simplified program input by a one-step assembler and implementation of Tiny BASIC that was popular among microcomputer users at that time, the Lkit-16 greatly contributed to the expansion of computer knowledge from would-be engineers to amateur users who were interested in microcomputers.[4]

  • Equipped with an audio cassette interface[5]

Merge with USAC Electronic IndustrialEdit

In 1987, PANAFACOM Limited merged with USAC Electronic Industrial to create PFU.[6]
