Apple Lisa Pascal compiler sources

Posted on July 24, 2024 by hanso

I found an archive with the source of the early Lisa Pascal by Silicon Valley Software.

The archive contains images of Lisa disks in dc42 format. In these disk images are the sources (and more) of the Silicon Valley Software Pascal compiler for the Lisa.

Andy McFadden (of Ciderpres fame) analyzed this and found out you can read these disk images on a MacIntosh (10.11or later) with AppleSauce software, as he showed me in the following screenshot:

Now I need the help of a MacIntosh user to extract the source file! Please help me!

Pascal-VU compiler

Posted on March 23, 2024 by hanso

During my study at the VU Amsterdam in 1979, 1980 I worked with the Pascal-VU compiler. A full ISO standard pascal compiler, in the spirit of the Px compile/interpreter.
I have saved several documents from that period, User Manual and Description of the EM machine, the inetrpreter for the p-code coming out of the compiler.

Since Pascal-VU and EM were transformed to the Amsterdam Compiler Kit by Andrew Tanenbaum and his team, some other documents leading to the ACK are also available:

Pascal-M updates

Posted on March 23, 2024 by hanso

New developments for Pascal-M:

Pascal-M for Flex OS on 6809 , 1980, source of compiler (in Pascal-M) and intepreter (6809 assembler for Flex) sent to me by Mark Rustad.
This version of Pascal-M is a further development of Pascal-M, 1978. Noteworthy additions are Reset and Rewrite for files and Value statement for initialization declarations.

Pascal-M for CPM65 (runs on the NE06502 and other 6502 systems supported by CPM65.
A further development of Pascal-M 2K1, with file I/O in standard Pascal syntax (Reset, Rewrite, Status, Close) and command line parameters.
Lots of improvements in compiler and interpreter. By David Given.

New version of the Pascal-M system 2K1

Posted on February 14, 2022 by hanso

New version of the Pascal-M system, run Pascal programs on the KIM-1.

Use it on a KIM-1 and cross compile on Windows or Ubuntu or Raspberry PI OS (or compile it on your favorite OS).

Per Brinch Hansen pages updated

Posted on October 27, 2020 by hanso

After the scan of Brinch Hansen on Pascal compilers I went on and also scanned the book on Edison: Programming a Personal Computer.

The Per Brinch Hansen now are updated too, the Alfred Hartmann book on Concurrent Pascal added, the Software: Practice and Experience issue on Edision scanned and converted, all articles by per Brinch Hansen listed. Enjoy the works of one of the pioneers: simplicity and parallel programming Per Brinch Hansen!

Scanned version of Per Brinch Hansen on Pascal compilers book added to the Per Brinch Hansen page, as well as the book Operating Systems Principles.

Edsger Dijkstra

Page on Edsger Dijkstra has seen an update, Books and such on this amazing scientist, who lived in Nuenen long time ago, 10 km from where i live now. Last time I have seen him was in 1980 in Utrecht, where he gave a speech together with Niklaus Wirth and Tony Hoare at the University.

UCSD p_system updated

Posted on September 3, 2020 by hanso

The UCSD p-System part of the site has been enhanced with all I had in my archive. This descendent of the P2 compiler, initiated by Ken Bowles and his students at UCSD, had a big impact around 1980 as a full operating system and with programming languages (Pascal, Fortran, Basic, Modual-2, Ada) in a well-supported portable way. A forerunner of Java, running on small computers like the Apple ][ and CP/M systems. The simple text based user interface and the p-code interpreter were strong points, but were later a disadvantage when native systems and compilers and GUI’s took over. Around 1985 the commercial impact was gone.

Many books, disk images etcetera.

The MS-DOS hosted p-system Supplement book has been scanned by me, the first time!
