- Yup. With the state of compilers and microcomputers at the time, the only viable mass-market targets for the Unix version of the sources would have been the Mac and the Amiga. But those already had native interpreters by the time they had C compilers capable of building this source.
- Beyond Zork’s map drawing code will also produce an ASCII art variant of the map for systems that can’t easily handle the custom font, like, IIRC, the Apple II.
The Infocom dev machine was a DECSystem 20 (PDP-10 architecture) until circa 1988, when they ported tools to the 68020-based Mac II.
I expect they thought the Unix source would be a good basis for future non-Unix development; comments in the source itself allude to this possibility; I’m just wondering if it was used in any shipping product. I suspect it wasn’t.
- You have to wonder, what would modern CPUs look like if Thompson and Ritchie had implemented unix on a PDP-10 and that had become the 'normal' for CPUs...
- I actually don't think any UNIX variant ever shipped as a commerical product. My gut feeling while working on the project was that it was perhaps a reference implementation, documenting proper z-machine behavior the various assembly versions needed to match. But that's a literal guess, TBH.
The list of known system codes (used as identification for packaging and so forth) can be seen here: http://pdd.if-legends.org/infocom/fact-sheet.txt
- When the game Beyond Zork starts up, it asks the Z-Machine interpreter what platform the interpreter is running on. If it's a platform that supports graphics, the game uses a custom font to draw an on-screen map; if it's a platform that only supports text, it does not try to draw the on-screen map. If it's a VT220, it uses the VT220's built-in special characters to draw the map.
Probably nobody was buying a special VT220 edition of Beyond Zork, I think that version was used by the developers working at Infocom, who did their work on a minicomputer and terminals. I believe it was a VAX, rather than a Unix minicomputer, but it wouldn't surprise me if the Unix Z-Machine interpreter had a similar story behind it.
- Does anyone know what games the Unix Z-Machine originally shipped for, if any, and for which machines? There wouldn't have been high demand in 1985 for a Unix version of Infocom games (understatement). There are mentions of the "AT&T PC" in the source, and a snippet of 68000 assembly language.
There's a Fooblitzky interpreter too, but that didn't ship for anything Unixlike.
- It was clearly a very popular machine with users; there was no real business case for producing clones, and yet there were no less than 3 companies that attempted PDP-10 clones -- one of them in the mid 1990's! -- in addition to the one-off clone at Xerox PARC. Ritche and Thompson wanted one at Bell Labs to develop early Unix (and settled for a PDP-11 instead). And DEC threw it completely away in 1983 by stopping development on the successor machines. They could have done one at least more generation, and it would have been at least a modest success and kept some of those users on board the DEC train.
- It needs a 35K memory expansion and a disk drive.
- Did anyone try this? how much memory do you need to run this ?
- That's some way to relive the trauma, add to that at least in my case that the tape was also a hit or miss, wonderful afternoons retyping things in that lovely keyboard. AAAAAAAAAAAAAAAAAAAAARGH!

Wow. Just....Wow.
- Nice. A huge treasure trove of info
- This is.fascinating as it was written for machines with ks of memory and maybe megs of storage.

- Well worth diving into the entire site. Lots 6502 and Atari-2600-adjacent tools. Great spacewar emu and discussion posted here before: https://www.masswerk.at/spacewar/index.html
- I wonder what the cheapest alternative to the pi5 is that could still run smoothly.
- The irony of this made me LOL. A break and enter is often called a Bert And Ernie. Here’s an example of a digital one.
- > The Righteous 3D had mechanical relays that clicked audibly when you were using it
Interesting! I assume these had something to do with bridging to the 2D graphics card? I found other references on the web to the relays clicking, but not an explanation of what the relays are doing, or how often you'd actually hear them in practice.
- Yeah, love the int10h font collection!
Already have them all, and also the actual Sun console font :)
- I had totally forgotten this technology was a thing in the PS/2 era.
- TIL, Plan 9 has a Raspberry Pi port. I feel like I need to build up a Pi to run this so I can claim to be a rebel against the sea of Linux.
Also, the fact that they called the thing to playback Youtube video Treason made me LOL.
- I was in high school and university when this scene was at its prime. I was always amazed by the effort that went into composing, announcing, and promoting specific distributions. The PC scene operated on an industrial scale, primarily supplying exotic ASCII and ANSI art in file_id.diz files and titles associated with handles like "Prez" and "Warez." In contrast, the Amiga and Mac clans displayed more panache by incorporating audio and animations.

- Even if not persistent it’s the kind of hack that should give MS a load in their pants. Xbox basically runs a version of hyper-V - same as used by Windows, Windows Server and Azure. While the vector may not exist it’s still flawed code.
Sigh.
