Published in 1984, this brochure detailed how Spectravideo computers could be put together as a local area network for use in classrooms.
It mentions a key piece of hardware (required in the master computer and each of the slave computers), a network card labelled as SVI-809 Network Interface Card (Expansion adapter needed for slave computers) for original Spectravideo machines, and SVI-709 Network Interface Card for any MSX computers.
The master station was listed as an SVI-606 Master Station, which included:

- A 10MB Winchester Hard Drive
- A 320k 5 1/4″ Floppy Drive
- An 80-column card
- A Parallel printer interface
- 64k Dynamic RAM
- RS-232-C interface cartridge
- The LAN interface
- and the LAN software
It would be interesting if one of these units existed in physical form, even if it was only a prototype.
