Whoa, the source code to #PostScript has been published already three years ago, by the Computer History Museum. (Some old version with little practical use today, I assume.) Might be an interesting read. PostScript is such a fascinating language.

It's annoying how badly developments in CPSI (Common PostScript Interpreter) are documented or are disappearing to a black hole somewhere in archive.org.

The CPSI exists in printer firmware that runs a licensed copy of Adobe PostScript 3 software that the printer manufacturer has to pay for. Don't cheap out on printers!

@darkuncle aaaahhh fond memories of the time a lazy sysadmin distributed the new corporate font to every printer in the company by writing some dodgy #PostScript that broke the networking stack.
