A good discussion of the interpreter is available in Inside PostScript (by Frank Merritt Braswell, Systems of Merritt & Peachpit Press 1989, about $40, white cover), which essentially takes one on a tour of the standard internal PostScript code in most printers. The author spelunked around in the interpreter and figured out how most normal stuff worked (in PostScript terms, no low-level hardware stuff here like cexec and internaldict).
