EMMY based PDP-11/20 emulation. Technical note No. 110

Technical Report ·
OSTI ID:7311459
An EMMY-based stand-alone PDP-11/20 emulator and its support system are described. The emulator reflects nearly all user-accessible aspects of the PDP-11/20 architecture as tested by the system diagnostic routines. I/O is emulated to the extent necessary to support paper tape-based software packages, and the system has executed unmodified EDIT-11, BASIC and PAL-11A (assembler) programs. This report serves two purposes: first, to describe the emulator and its performance, and second, to provide a guide to EMMY Laboratory users wishing to use the emulation system. 14 figures.
