KAYPRO portable computers can be linked via the Kaynet, a network that is the product of joining several vendors' technologies. The principal component of the network is the Web high-speed network transceiver and interface, developed by Centram Systems. The networking software, OPSnet, is supplied by Aquinas Inc., and supports most CP/M version 2.2 programs without modifications. The network is a baseband CSMA/CD-CA design which operates at 125Kbps. Standard telephone wire can be used to connect the various computers on the network; any of this vendor's line of portable computers can be hooked into the network. The network uses no dedicated network file or print servers, since each cpu on the network acts as both server and local processor. In that way, any computer can replace any other to maintain the network in the event of a failure of one of the portable computers. The networking capability, including the add-in card and the software, is available as a $200 option to Kaypro computers at the time of purchase. A typical four-user system could consist of 20MB of hard-disk storage, six floppy disk drives, and a full software package, all spread over the resources of the network. The largest practical net can include up to about 20 computers, although the vendor says three times the many can be linked together. KAYPRO CORP., Solana Beach, CA. (from Datamation, Oct. 83)
