NABU Network

The NABU Network (Natural Access to Bi-directional Utilities) was an early home computer system which was linked to a precursor of the World Wide Web, operating over cable TV.

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 full-duplex UART, an SC87253P 8-bit microprocessor, an N8X60N FIFO I/O controller and a pre-programmed ROM.

There were four circuit boards for frequency synthesis, data in and out and RF conversion and dual helical coil bandpass filters.

The fact that network access was limited to the NABU Personal Computer, forcing the subscriber to buy it, was mentioned as problematic by 1984, with the company accumulating $5 million losses.

[21] On November 26, 2022, Adrian Black, creator of the YouTube channel Adrian's Digital Basement, published a video showcasing a NABU PC[22] however, it did not come with the adapter that was required for the computer to operate properly; and so he reached out to the community for help on getting his unit operational.

[23] Another YouTuber, DJ Sures, had published a video four days prior showcasing another NABU PC, and began working on how to program it.
