UCSD p-System IV
The UCSD p-System is a highly portable operating system. It uses the Pascal programming language, and all applications are compiled to interpreted bytecode. This means an application written for the p-System should run on any p-System platform, regardless of the CPU and architecture. However, depending on the use, it could be quite slow.
A number of commercial applications were written for the UCSD p-System, but it lost its portability advantage as the industry standardized on the x86 IBM PC architecture.
