Sun Microsystems Inc’s Alameda, California based Sitka Corp neither company seems to want to acknowledge the other very much these days, is now into networking software for penbased computers and reports that IBM Corp has licensed its PenCentral software technology. PenCentral is claimed to be the first networking server technology to connect pen computers with MSDOS-based personal computers via parallel port, serial port or modem. Sitka and Go Corp jointly developed PenTOPS, the client version of the pen-based network offering, which is bundled with every copy of the PenPoint operating system. Sitka Corp also has a developer’s programme to provide networking tools and support for people building pen-based applications, based on the PenTOPS family. Phase two of Sitka’s pen networking products will include a full implementation of the OpenTOPS architecture, and an implementation of deferred inputoutput for PenPoint document transfer. PenTOPS will support notepadtonotepad file sharing.
