Company:NABU Network

From HandWiki

The NABU Network was an early home computer system which was linked to a precursor of the Internet, operating over cable TV. It operated from 1982 to 1985, primarily in Ottawa, Canada. Its functionality was then revolutionary, though it was not a commercial success. It has been called "The Internet — 10 years ahead of its time" [1] (even though elements of the history of the internet predate it).

Functionality

Families, schools, or individuals would purchase a NABU Network PC, which would be connected via cable TV to NABU's servers. In addition to normal PC capabilities of the time, the computer could download software and information content through the cable feed and could upload primitive information back up to the servers. Applications included games, the programming language Logo, news/current events, and rudimentary PC banking/shopping. At its peak, approximately 100 applications were available.

The NABU Network can be credited as being the first online version of fantasy baseball. The Game, aptly named Managers Baseball, allowed for choosing teams based on the real names and statistics of MLB teams and players. Player performance in the game was based on real life player statistics and as a Manager you would draft your team and compete against another owner in a mock up game in a purely managerial role.

The NABU Network PC cost $950 CAD, approximately the same price as the wildly successful Commodore 64 at the time, and the network service cost $8 to $10 per month.[2]

Hardware

The heart of a NABU PC, short for Natural Access to Bi-directional Utilities, was the Z80A processor chip running at 3.57 MHz and the Texas Instruments TMS9918 video chip. Data was served via a Gould SEL minicomputer. By default, the PCs lacked any individual offline storage, but an optional hard drive could be purchased.

The interface module included four socketed chips: a TR1865CL-04, a full-duplex UART, an SC87253P 8-bit microprocessor, an N8X60N FIFO I/O controller and a pre-programmed ROM. The remainder of the parts on the board were numerous 74LS series logic ICs. There was an RF module that down-converted signals from the cable connection and up-converted requests to be sent to the server. There were four circuit boards for frequency synthesis, data in and out and RF conversion and dual helical coil bandpass filters. Download speeds over the cable TV line were up to 6.4 Mbit/second.

Business success

The NABU service first became available in 1983 through Ottawa Cablevision and Skyline Cablevision, through the efforts of John Kelly and Bruce Hempell. The project was heavily subsidized by the Canadian government. A major weakness of the Ottawa network was the strictly one-way connection as it was implemented on Ottawa Cablevision. The NABU system itself was bi-directional, but most cable networks of that era did not support this feature due to the cost required for a bidirectional cable infrastructure — a "chicken and egg" problem that limited NABU's market potential.

Campeau Corporation was a major investor in NABU but pulled out in 1984.[3][4]

Another network was started in Japan . However, NABU never achieved commercial success and ceased operation in 1985.
