VideoBrain Family Computer
The VideoBrain Family Computer (model 101) is an 8-bit home computer manufactured by Umtech Incorporated, starting in 1977. It is based on the Fairchild Semiconductor F8 CPU. It was not a large commercial success and was discontinued from the market less than three years after its initial release. Some of its lack of success has been attributed to the decision to substitute the APL/S programming language over the then-standard BASIC. Due to the high cost of RAM memory, it only contained 1 KB. It had a full-travel keyboard, unlike some early home computers that featured membrane keypads (and earlier kit machines that used switches), but with a very non-standard layout. It was designed by David Chung and Albert Yu.
The VideoBrain Family Computer was designed and produced by Umtech Inc., doing business as the VideoBrain Computer Company of California in 1977. It was not widely available, although Macy's department store briefly carried the computer on its shelves. It was sold in various configurations, and the price ranged from $500 to $1100 depending on the accessories chosen. New software for the VideoBrain was available on cartridge, which was a first for home computer systems (Later price reductions brought costs down to $300 for the computer by itself, and $350–900 for the packaged deals).
Available software ranged in price from $20 to $40 for video games and educational software, and $70 to $150 for productivity tools.
The VideoBrain Family Computer was built around the F8 processor from Fairchild Semiconductor, and featured 1KB of RAM and a 4KB ROM. It was able to output 384 x 336 graphics and 128 x 56 semigraphic characters in 16 colors, (based on UV-201 and UV-202 proprietary chips) and sound to a connected television set through an RF connector. By far its most striking feature was the 36-key keyboard - though the keyboard of the VideoBrain was poorly designed and difficult to use, keyboards were not available on any of the more common video game consoles of the time. Some popular kit-based computers also typically lacked a keyboard, opting for toggle switches instead. The system also features four joystick ports, a cartridge connector, and an expansion port.
The system included four built-in software titles, available if the unit is powered on without a cartridge inserted - a simple text editor, a clock, a countdown timer, and a Color Bar generator.
Two additional hardware modules were marketed that would extend the capabilities of the VideoBrain. The Expander 1 was an interface to various I/O devices. It allowed users to connect a cassette tape recorder for saving or loading data, and included two RS-232 ports for attaching a printer and the Expander 2. The Expander 2 was a 300 baud acoustic modem used by a single program (Timeshare) that allowed the VideoBrain to act as a terminal when dialed into a compatible mainframe computer.
Additional software was sold on cartridges measuring approximately the size of a Betamax tape. The cartridge interface was unique: unlike most video game systems, VideoBrain cartridges had an exposed strip of conductive traces that simply lie flush against a set of pins on the computer itself. Cartridges could contain up to 12KiB of data.
Patent 4232374 titled "Segment Ordering for Television Receiver Control Unit" describes the VideoBrain display hardware.
