VideoBrain Family Computer


VideoBrain Family Computer

The VideoBrain Family Computer (model 101) is an 8-bit home computer manufactured by the VideoBrain Computer Company, starting in 1977. It is based on the Fairchild Semiconductor F8 CPU and is notable for being the first fully programmable cartridge-based home computer. It was not a large commercial success and was discontinued from the market less than three years after its initial release.

History

The VideoBrain Family Computer was designed and produced by 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 dollars 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)cite news | first= | last= | coauthors= | title=VideoBrain | date= | publisher= | url =http://www.obsoletecomputermuseum.org/vidbrain/ | work =Obsolete Computer Museum | pages = | accessdate = 2007-11-30 | language = ] .

Available software ranged in price from $20-40 for video games and educational software, and $70-150 for productivity tools.

Design

The VideoBrain Family Computer was built around the F8 processor from Fairchild Semiconductor, and featured 1KiB of RAM and a 4KiB ROM. It was able to output 16-color graphics 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 timecite news | first=Bill | last=Loguidice | coauthors= | title=Photo of the Week - Know your History!

The system also features four joystick ports, a cartridge connector, and an expansion port.

The system includes 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 in to a compatible mainframe computercite news | first=Matt | last=Reichert | coauthors= | title=AtariProtos.com - VideoBrain | date= | publisher= | url =http://www.atariprotos.com/othersystems/videobrain/videobrain.htm | work =AtariProtos.com | pages = | accessdate = 2007-11-30 | language = ] .

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 have 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 datacite news | first= | last= | coauthors= | title=VideoBrain | date= | publisher= | url =http://www.obsoletecomputermuseum.org/vidbrain/ | work =Obsolete Computer Museum | pages = | accessdate = 2007-11-30 | language = ] .

Software

Because the VideoBrain computer was discontinued so quickly, fewer than 25 software titles were ever marketed for the system. The library comprises a handful of games, educational titles, and productivity softwarecite news | first= | last= | coauthors= | title=VideoBrain | date= | publisher= | url =http://www.obsoletecomputermuseum.org/vidbrain/ | work =Obsolete Computer Museum | pages = | accessdate = 2007-11-30 | language = ] . Notable titles include:
* Financier - this cartridge shipped with the VideoBrain, and could be used to solve financial equations.
* APL/S - the only programming language available for the VideoBrain. The tape connections of the Expander 1 could be used to load and save programs.
* Timeshare - the only program to use the Expander 2. This would transform the VideoBrain into a timeshare terminal.
* Demonstration - this cartridge was intended for store displays as a way to show off the VideoBrain's capabilities.

Reception

Unfortunately, the VideoBrain largely failed to achieve commercial viability for a number of reasons. Poor design decisions hindered user acceptance; for example, the VideoBrain's confusing and user-unfriendly keyboard made even simple text entry a tedious process. Moreover, the computer did not offer the then-popular programming language BASIC, forcing users to instead to adopt APL/S - a far more obscure and difficult programming language. Finally, the VideoBrain software library had trouble reaching a key audience. Most available software was aimed at productivity or educational markets, and lacked any variety of entertainment titles.

Perhaps the largest contributor to the VideoBrain's failure was simply a lack of proper marketing and hardware availability. Public understanding of computers in 1977 was significantly lower than it is today, and many potential consumers simply did not understand the benefits of owning a home computer. Additionally, the VideoBrain was mainly sold through mail-order outfits, and only made a brief retail showing at Macy's Department Stores. (By contrast, video game consoles at the time were easily available in a number of department and toy chains, allowing them to far outsell the VideoBrain Computer System)cite news | first=Matt | last=Reichert | coauthors= | title=AtariProtos.com - VideoBrain | date= | publisher= | url =http://www.atariprotos.com/othersystems/videobrain/videobrain.htm | work =AtariProtos.com | pages = | accessdate = 2007-11-30 | language = ] .
