The model number was FM-16s, and it was sold in the USA from about 1983 to around 1985.
It had dual processors on daughter boards, one with a Zilog Z-80a and the other with an i8086 on a true 16-bit bus. Hard drives were external, connecting through a SCSI host adapter. The machine could have up to 2MB of RAM on a proprietary expansion card, and ran at 8MHz. It had a 640x480 16 color display and 104 keys keyboard.
CP/M-86, WordStar, SuperCalc and the C/PM-86 operating system were bundled with the basic purchase; but the FM-16 could also run CP/M 2.2, a proprietary version of MS-DOS 1.0, Concurrent CP/M-86 and PICK. If all were installed in partitions on the hard drive, you had a choice of OS at boot time.
Ron Edelstein adds:
Actually, the FM-16s had a video of 640x400 (not 480). It was a double-scanned format using 16 colours. Much better and sharper than the later IBM EGA standard, even though IBM used 480 lines. Using a proprietary version of MS-DOS, it could run any software not requiring graphics (i.e. text mode). The difference in video prevented it from displaying IBM graphics displays unless they were specifically recompiled for the FM-16s, as were SuperCalc and WordStar.
