I have tried to transcribe the Z-machine YZIP specifications as close to the original as possible.
Throughout the document there are a number of comments from an unknown proofreader that I have incorperated as much as possible, otherwise the document tries to be as faithful as possible to the original.
I have also added hyperlinks in the ”Table of Contents”, the ”Index” and some internal references.
I have used the font “Bookman Old Style” throughout the document.
If you’re uploading the ZMS 1.1 document and incorporating corrections, there are a couple of places where the string “$1\times 1$” shows up that I’m pretty sure should just read “1x1”. (These errors are faithfully replicated in the online version.)
Yes. I used this as a source. The ZIP, EZIP and XZIP was already transcribed so I went along and did the YZIP. The ZIP, EZIP & XZIP should probably also be uploaded but because I didn’t produce them myself, I’m a bit hesitant to do that.
The string $1\times 1$ appears both in ZMS 1.0 and ZMS 1.1 in chapter 8 and chapter 16. The text in chap. 8 is:
It's recommended that a Version 5 interpreter always use units to correspond to characters: that is, characters occupy $1\times 1$ units. 'Beyond Zork' was written in the expectation that it could be using either 1x1 or 8x8, and contains correct code to calculate screen positions whatever units are used. (Infocom's Version 5 interpreter for MSDOS could either run in a text mode, 1x1, or a graphics mode, 8x8.) However, the German translation of 'Zork I' contains incorrect code to calculate screen positions unless 1x1 units are used.
and in chap. 16:
9. (Apple IIc) 'BZ' uses Apple character graphics (possibly "Mousetext"), but has
problems when the units used are not $1\times 1$.
The text doesn’t make much sense to me, but is it correct with 1x1 instead of $1\times 1$ or does the latter mean something I don’t understand?
