Symbolics Inc, which is now relocated to Burlington, Massachusetts from its original home in Cambridge, has extended networking support for its 3600 series of artificial intelligence workstations with the introduction of communications products that support the X-Window System from Massachusetts Institute of Technology, and Sun Microsystems’ Network File System. Symbolics X-Windows software is based on the Unix-based X-Window Version 11, and is designed to enable symbolic applications developed with Symbolics’ Genera software to be delivered simultaneously to multiple end-users sitting at low-cost remote consoles. Symbolics-NFS is a Lisp implementation of the Network File System protocol, and the company says it was developed specifically for workstations running Symbolics’ Genera development software. Symbolics X-Windows and Symbolics-NFS are available immediately in the US for the 3600 family of workstations, with X-Windows at $1,700 NFS at $1,000.
