Additions to the Jim Welsh pages, Queen’s University Belfast and Emerate Professor at The University of Queensland Brisbane, School of Information Technology and Electrical Engineering – 1900 Pascal User’s Guide,- Sources of 1900 Pascal Compiler MK 2.

As explained in the next Summary, the CDC compiler was ported in a number of steps to the 1900 computer.

Not all sources of the Pascal compilers survived time. <Here are the sources of the 2A version, a further developed ETH type compiler. Still recursive descent down like the ETH ones. Compiler source, post-mortem dumppsource, and ICL 1900 runtime assembler source

This compiler differs of course in the code generation to ICL 1900 machine code.
