Yes it did have three blocks of video ram, but it was still one bit per bank, per pixel so you still only have 8 colours. The graphics library supplied supported dithering to create a greater colour palette. - author: Adrian Pearson (USA) date: Wednesday 2nd September 2020 text: I found a USA advertisement for this BMC computer in a 1981 issue of Byte magazine. https://archive.org/details/byte-magazine-1981-04/page/n117/mode/2up - author: Aleem (Pakistan) date: Friday 4th November 2016 text: When I was with Patfinder computers these were introduced and used for training at Comptrain - author: Gary Sharp (Vietnam) date: Saturday 2nd April 2016 text: |- Wow, that is a flashback I bought 4 of these for the Architecture Faculty of Newcastle University , must be early 1980''s to teach Arch students, Visicalc, Wordperfect $i think$ and basic graphics.

My task was to re-write an infra-red imaging and analysis system - and I had a year to do it. For technical documentation I had a blurry printout of the boot ROM.\ The system had been bought for its colour graphics capability - and it really worked...you had three blocks of RAM for RGB$ from memory I recall it mapped two bits to each pixel - ie 16 colors, or 4 pixels per byte. To get more colors you could simulate 4 bits per pixel to get 128 colours (although many were identical) at half the pixel resolution. Great fun.\ Mine also had a row of programmable function keys under the monitor, which I used to control the main menu of my imaging system. oc_id: 94 source: url: https://web.archive.org/web/20230601001458/http://www.old-computers.com/museum/computer.asp?c=94 date: '2023-06-01' --- 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.
