Now on with V1.5 which will have a native GUI debugging interpreter in Freepascal.

Pascal-M 1978 Cross compiler
The original 1978 version of Pascal-M, a P2 descendent, has been restored. Original source, which can compile itself, is now available, as a cross compiler, an interpreter in Pascal with debugging facilities, a binary loader for the KIM-1 6502 interpreter and a disassembler for M-code. Together with the already available source of the KIM-1 V1 interpreter all parts of the 1978 compiler are now available in source and compiled/assembled format.
Though compiling itself is a very good test of the compiler, which showed many bugs from typing in and some original present bugs, not too much testing has been done.
I start working now on V1.5 of the cross compiler and leave this V1.0 version as ‘completed’ and ‘historical purposes’.

This site is about my experience with the Wirth school of languages, based on the ideas and implementations of Prof Niklaus Wirth, Kenneth Bowles, Per Brinch Hansen, colleagues, and their students. And my experience with the various variants, from the P2 and P4 compilers originating in Zürich ETH, via UCSD Pascal P-System to the Borland compilers and Modula and Oberon systems. All applicable to small computers and device control.
On this website you will find information on Pascal for small machines, like Wirth compilers, the UCSD Pascal system, many scanned books and other files on UCSD Pascal, Pascal on MSX and CP/M, Delphi programming on PC, Freepascal and lazarus on Windows and Raspberry Pi, Oberon systems. Many sources of early Pascal compilers!
