Pascal for small machines

Links to Apple/UCSD Pascal and p-System information

Apple has a long history with Pascal and UCSD Pascal as Apple Pascal. Read this history paper by David Craig about Apple Computer's Pascal versions.

Dave Tribby has an interesting Apple Pascal page. On that page is a disk image containing a disassembly of the Apple Pascal 1.3 p-machine interpreter and more. Here is in text format the (thanks to Paul R. Santa-Maria) listing file of just the interpreter.

Page by Mark Riordan about the Terak machine, the first mass target of UCSD Pascal and an UCSD Pascal pricelist

UCSD Apple Pascal interpreter for Linux by Mario Klebsch Written in C for Linux, it is a complete emulated Apple Pascal system. If you know how to build it on a modern Linux distro, please let me know!

History of UCSD versions

The SAGE computer, produced in the 1980’s by SAGE Computer Technology , is a 68000 cpu based with a version IV implementation of the p-System. David Erhart has collected much information on this machine at Sage computers. Of much interest are the version IV manuals like Internal Architecture manual and p-System Operating manual.

Peter Miller has pages on:

• The ucsd-psystem-fs package is used to mount UCSD p-System filesystem disk images as Linux file systems. It also contains a number of other useful UCSD p-System filesystem
• The ucsd-psystem-um project is reconstructing the II.0 user Manual.   
• A page contains source code for UCSD p-System version 2.0. The contents here are derived from the material available at Bit Savers, and its various mirrors.
• The ucsd-psystem-xc project provides a Pascal cross compiler for producing UCSD p-System code files on Posix hosts, such as linux. It also provides some other related tools, such as a disassembler.
