Of course the first thing that happens is someone corrects my chronology. (Thanks dukdukgoos!)
In my original post, I wrote "March: Zork 3; April: Starcross; May: Deadline." In fact Deadline was released before the other two.
Back when I put together my Infocom catalog index page, I copied off Paul David Doherty's venerable Infocom Fact Sheet. Except I think I copied the wrong section. Or something. Anyhow, I got them out of order -- and then failed to recheck my own list when I planned the Patreon.
To double-check, let's look at Margot Comstock Tommervik's review of Starcross:
If it takes a minimum of two instances to form a proposition, then Starcross, adventurous Infocom's first foray into science fiction and second departure from the dungeons of Zork, enables the proposition that this young company is one of remarkable versatility [...]. Deadline, the you-solve-it mystery, was, of course, instance one.
-- from Softalk Magazine, Nov 1982
Zork 3 was reviewed a couple of months previously, if you want to check that. In fact the archives of Softalk and Softline are a great record of the first half of Infocom's career; they reviewed the games obsessively until both magazines shut down in mid-1984.
(You can browse these Infocom articles and many more at the Invisiclues fan site.)
Those contemporary sources match the "Chronology" section of PDD's Fact Sheet:
- Zork 1
- Zork 2
- Deadline
- Zork 3
- Starcross
- Suspended
- The Witness
- Planetfall
- Enchanter
- Infidel
- Sorcerer
- Seastalker
- ...and so on.
(Those are the "Folio" game releases. After Seastalker, Infocom adopted the now-more-famous "Grey Box" format.)
Interestingly, if you look at the earliest preserved serial number of each game -- excluding files tagged "alpha" or "beta" -- you get the same order. This means we probably have the first-shipped version of every game. Nice to know! You can also see that development on each game was usually locked the month before the ship date. Not bad for a release process that involved stuffing physical disks into physical boxes.
Anyhow, I'm keeping Zork 3 at the top of the Patreon schedule (March). I want to wrap up the trilogy right off the (Babe Flathead) bat. If everything moves forward as planned, I'll do Deadline in April, Starcross in May, and so on.

@et_andersson I hope to do some nice charts, but I’ve never looked at the Deadline code at all, so I can't say yet. One thing at a time, Royal Puzzle first...
@zarfeblong I imagine that the Royal Puzzle won't cause too much trouble. As far as I understand, CPTABLE holds the current state of the map, and CPHERE tells which room you are in.
You will probably spot a couple of bugs in it when you get there, though.


@zarfeblong Deadline sounds like it will be visually interesting. I never did figure out exactly how that path finding worked, beyond some vague ideas, so this might help.
