Abstract:

A computer program was developed to simulate the operation of the Digital Equipment Corporation DEC PDP-12 computer at the register transfer level. The program is written in FORTRAN IV Extended language, and it is designed to be used interactively from teletypes under control of the Control Data Corporation 6600 computer INTERCOM system. The program emulates the PDP-12 front console, the PDP-8 mode set of instructions, the LINC mode set of instructions, and the DEC PAL III assembler program. The execution of input and output instructions for the teletype and two types of simulated storage devices are also emulated. The thesis discusses the overall organization of the emulator program, the routines which emulate the LINC mode set of instructions, the inputoutput routines which emulate special storage devices, and the assembler program. A supplement to the Minicomputer Emulator Users Manual is also provided which contains program examples and material reflecting the additions and changes made to the PDP-12 minicomputer emulator program.
