This computer had an integrated dot printer which can print on 40 to 132 columns at 120 cps, a 12" color graphic monitor and a dual 5" disc drives. A lot of cards were designed to be placed into the three expansion slots: an 8" disk controler, centronics interface, IEEE488 port, ADC/DAC card or ram expansion (64 or 128 KB).

A bit of trivia: the video card has its own Z80 CPU.

Apparently this computer was marketed by BMC outside Japan.

Alexander Velin says :
There is OKI if 800 model 50, which is based on 8086, has 256 KB ram, spare keyboard, one 8" 560 KB floppy, 7 MB HDD. Mine has a MS DOS 1.15 on it...

More technical information from Bruce Grant:
I serviced IF-800's in the early 1980's.
The printer was a 7 pin matrix mechanically related to the Oki Microline 82 but largely software driven. It was a frightful device.
Both colour and monochrome screens were offered, and were excellent. The colour monitor had, as I recall, three seperate banks of 16K of RAM, one for each of the primary colours, providing an early form of 24-bit colour. Power for the main unit was provided through the monitor. Two people were needed to safely carry the colour monitor.
The floppy disks were made by YE-Data and offered good capacity for the time - in the order of 500KB. They were of the solenoid head loading type and were ponderously slow but generally quite reliable.
CP/M 2.2 and a standalone version of MS-Basic were supplied. Each system used its own disk format. Sadly, these were not interchangeable. Bitmapped graphics were implemented through the MS-Basic system only, as were the bezel-mounted screen "hotkeys".
The IF-800 was crippled commercially by appearing on the market at the same time as the IBM PC-XT, which cost slightly less as I recall.
They were distributed in Canada by Canada Computer of Markham, Ontario.
