The Spectravideo SVI-809 is a LAN interface manufactured in 1985. You need a SVI-328 and a super expander to use it. The official name is "Network Interface Card".

The transfer rate is up to 10M bits per second. Connectors type are two modular connectors 6P6C with 4 wire used.

This cartridge transforms your computer into a station in the SVI-609 Local Area Network. Maximum 32 stations can have access to the mass-storage and rapid printing resources of the SVI-609 Master Station.

Each slave station can make use of a portion of the SVI-609's 10MB Seagate ST-212 SASI MM hard disk (WD1002-SHD) for its own file storage, and all stations can share a common storage area, printer spooler and software library.

The interface contains a ROM with the SVI BOND-NET communication software. After booting, you can press N to request log in or B to go to SVI-BASIC. In the first case, you need to enter a password to access the network. After 3 wrong passwords or when the Master Station does not answer, you go automatically to SVI-BASIC.

Note: There is also a model for MSX computers under SVI-709 reference. It is possible to combine MSX computers with SVI-328 machines in this network.
