Porting DPPX from the IBM 8100 to the IBM ES/9370: Feasibility and overview

by R. Abraham, B. F. Goodrich
The DPPX/SP operating system was converted from its original implementation on the IBM 8100 Information System architecture to a new implementation-PX/370- the System/370 architecture of the ES/9370 Information System processors. Portability was not an original design objective for DPPX, and yet the conversion of the operating system was straightforward and successful. This paper investigates the design fundamentals and technical approaches that led to the successful porting of DPPX/SP to the ES/9370.
