Printer Multiplexing Among Multiple Z-100 Microcomputers.

Abstract

This thesis describes the detailed design and implementation of a printer server in the laboratory environment of sharing resources among multiple Zenith Z-100 microcomputers. The Printer Server System is a controller box which consists of a power supply, a single board computer, and the BLC 8538 eight channel I/O expansion boards. Each Z-100 microcomputer is connected to the controller thru the RS-232C port. The Printer Server System has three software utilities: BOOT, CONTROL, and SPOOL. The BOOT process, resident in the controller, downloads the CONTROL file from any one of multiple Z-100's which is turned on. The CONTROL process allows the printer to be used by any one of multiple Z-100's at a time. The SPOOL process sends the data thru the CONTROL process to the printer or saves the data on the disk file. Keywords: Ethernet; CP/M-85 operating system. (Author)
