I spent a bit of time recently converting Infocom’s original Z-Machine specifications from the rather outdated markup formats I had them in to LaTeX. Then I got kinda distracted and started working on other stuff, but I thought other people might like to see this, so I’ve put it up at http://frobnitz.co.uk/zmachine/infocom/
The page has the original files I worked from, some LaTeX sources I produced, and PDFs of the specifications.
A note on this, I do plan to continue work on these files. My plan is to make the PDFs look, more or less, like the YZip spec PDF that contains images of a printed document. Maybe even make alterations to the text based on the notes written on that YZip document. Anyway, the point is, I’ll update the files without warning whenever I get around to it, but I’ll leave the original source files alone.
