ASSIST-V is "... a software tool designed for use in the teaching
of operating systems, file management and machine architecture
courses. ASSIST-V is a program that provides an environment for
the implementation, testing and evaluation of systems software for
the IBM 360 series machines. This capability is achieved by
simulating all relevant aspects of the machine's architecture. In
particular, ASSIST-V simulates interrupts, I/O channels, and I/O
devices, as well as all IBM 360 machine instructions. In addition,
ASSIST-V provides extensive debugging and statistics gathering aids."
ASSIST-V was developed by Charles E. Hughes (http://www.cs.ucf.edu/~ceh/)
and Charles P. Pfleeger (http://www.pfleeger.com/) with support from
the National Science Foundation and the University of Tennessee,
Knoxville. This software is, in part, a derivative of ASSIST, the
IBM System/370-compatible assembler/interpreter developed at Penn
State University by John R. Mashey and others. Neither the authors,
the University of Tennessee, Penn State University nor Northern
Illinois University can or will provide support for ASSIST-V.
You are welcome to use this system, but with the understanding
that any problems you encounter are yours to fix.
