Are there any papers, tech reports (etc.) written on implementing
PostScript (tm)? Or is that covered in the "Cookbook" published
by Addison-Wesley?

As Rick pointed out, the Cookbook (blue book) covers use, not implementation. The Reference Manual (red book) contains more information that indirectly reveals implementation details, like Appendix B: Implementation Limits. It also contains footnote references to two papers: 1. Warnock, John and Wyatt, Douglas: "A Device Independent Graphics Imaging Model for Use with Raster Devices", Computer Graphics, Vol. 16, No. 3, July 1982, pp. 313-320. 2. Smith, Alvy Ray: "Color Gamut Transform Pairs", Computer Graphics, Vol. 12, No. 3, August 1978 Reference [1] describes an imaging model very similar to the one used in PostScript. This is the most important part of the implementation. Other implementation details, like the organization of dictionaries and the "virtual memory", can be guessed after some experimentation with LaserWriter or another PostScript printer. The key operator for exploring the implementation is "vmstatus". Alex Abacus
