I recently saw this little excerpt from one of the GATEWAY newsletters posted to this newsgroup. Is there anyone on from the ISI Amateur Radio Group? I'd like to get more information on this hardware: We received the following letter from Richard Bisbey II, NG6Q: "The Information Sciences Institute Amateur Radio Group (WB6MXZ) has been on the air with a 56 Kb packet radio system since December, 1983. The equipment consists of 8088-based controllers using the Zilog 8530 SCC chip and frequency agile 10-watt FSK transmitters and receivers. The controller supports serial, parallel, and Ethernet connected devices. Assembled controllers cost approximately $650. The system uses standard INTERNET (IP/TCP) protocol, and in addition to supporting simple link level connections, supports internetworking as well as numerous high-level protocols such as TELNET, File Transfer (FTP), Mail (SMTP), Multi-Media Mail (MMM,MPM), Graphics (GP), Packet Voice (NVP), and Remote Virtual Disk (RVD). The hardware and software can support data rates as high as 1 Mb, well in excess of the current amateur limit of 56 Kb. "Previous packet radio accomplishments by ISI amateurs include a March 1982 demonstration of transcontinental packet radio internetworking between an aircraft flying above Los Angeles and a fixed station in Virginia, and a November, 1982, demonstration of intercontinental internetwork packet radio communications between Los Angeles, California and The Hague, Netherlands using Intelsat-4A. The ISI group is currently developing a low-cost spread-spectrum system with capabilities similar to the current non-spread system." This sure sounds like some serious packet radio work to me...
