FM R 70 wasn't just an expensive IBM Compatible, but a very sophisticated machine at its time featuring some newly added features common to most modern computers today. In example:
• It came stock with 584 KB Base Memory, and 2MB of Extended RAM Memory (in newly developed SIMMS).
• It featured a newly developed Cirrus Logic CL-GD video subsystem, adapted by many proprietary manufacturers of the late 1980's early 1990's.
• It featured an i386-DX processor, as well as an optional mathematics coprocessor.
• It ran at about 16Mhz and ran MS-DOS and any variations of PC Compatible software, as well as Miscrosoft Windows.
• It used the AT style Keyboard, 2 5" Floppy's, or one 3.25 Floppy and one 5" floppy, VGA/VESA technology and ISA bus.
• It also featured a Thomas Conrad ethernet adapter.
Preceding i286 processor models was called FM-R60 (high-resolution model) and FM-R50 (standard 640x400 dot resolution model).
R60 and R50 had a sub-model with HDD (FM-R60HD /FM-R50HD) and without HDD(FM-R60FD/FM-R50HD).
Mainly, these machines were used as a terminal of Fujitsu M-series(M-3xx/7xx) mainframe, with a F6650 connection card (interface card) and a F6680 emulator software.
We need more info about this computer ! If you designed, used, or have more info about this system,
please send us pictures or anything you might find useful.
The FMR-50, the predecessor to this machine, was actually the basis for the famous and fabled FM-TOWNS system. It is even possible to use FMR-50 expansion cards with the FM-TOWNS, provided you used a simple passive adapter. The ethernet card in my FM-TOWNS II UR is an FMR-50 ethernet card connected to an adapter. As far as I know, some FMR-50 will run unmodified on the FM-TOWNS as well.
