Our all-in-one BMC IF-800 computer is easier for dealers to sell, customers to buy and OEM to use in their systems...\
|
|
... You can upgrade to a 16 bit CPU which offers IBM PC compatible MS-DOS and CP/M-86...

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.

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.
