> Some code associated with Nedryland is visible on screen. It looks like actual source code[9] with Classic Mac OS API functions calls
The source code shown is example code included with the Macintosh Programmers Workshop, Apple's original IDE for the Mac. Originally sold as a separate product, eventually it was provided on the Developer CDs and then as a free online download as serious developers had moved to CodeWarrior. https://en.wikipedia.org/wiki/Macintosh_Programmer's_Worksho...
One of the windows shows the example for how to make a HyperCard XCMD and the other one looks like an MPW script for using Apple's Projector source control.

My wife worked for Thinking Machines back then. I remember that they'd asked Cray to loan them a supercomputer for the film because that's the computer used in the book. Cray brushed them off, so they turned to Thinking Machines who were happy to do it.
To thank them, the producers rented a theater in Cambridge, MA to screen the film just for Thinking Machines and I was also able to attend. By far the biggest reactions from the audience that night were when the CM-5 was shown for the first time and then when the young actress says, "It's a Unix system. I know this"
My uncle (John Monsour) worked on this movie as the “24 Frame Computer Sync Engineer”. Because film cameras and CRT monitors have different frame rates, you needed to use specialized electronics to synchronize them with the camera frame rate otherwise you would have banding and weird moving artifacts on all the screens. It’s crazy to imagine needing to do this for all the screens visible in these shots.
Later monitor technologies like LCDs don’t have this issue because they don’t have the same moving electron beam illuminating each line of pixels, and it also became cheaper to just replace all the computer screens with CG, so eventually this specialized technical work wasn’t needed anymore, and my uncle ended up doing other things on the movies he worked on.
It was indeed a Thinking Machines CM-5 — Nedry actually mentioned them in his line about how Hammond wouldn't be able to find anyone "anybody who can network 8 connection machines".
An actual assembled CM-5 actually cost closer to a million dollars.
But, from what I remember the one in the control room is a shell. In the CM-1 and CM-2, the LEDs were actual status indicators on the processors, which Tamiko Theil and the other designers had the engineers move to be at the edge of the boards, so that they'd shine through the case. Super cool.
But by the CM-5, they were run off a simple microcontroller.
They went bust not long after this movie.
I made a YouTube video on the history of the Connection Machine – it was a lot of work, and if you're interested in this sort of thing I think you'll enjoy it:
What a great post! I would love to read more of these for other films.
> Everything in the set was real. We couldn't fake any of it, because audiences are so sophisticated now in their knowledge of computers. > ... > - Cory Faucher (Special Effects Coordinator)
This sentiment seems to run throughout the movie, and I believe it's why it's held up so well in terms of visuals, I don't think it would have aged nearly as well as it has if more CGI (or other ways of "faking" things) had been been used.
As for the question (in <references[9]>):
> Some code associated with Nedryland is visible on screen. It looks like actual source code[9] with Classic Mac OS API functions calls.
That looks like old Pascal, and since the window has MPW (Macintosh Programmers Workshop) in the title, that's probably it?
I feel like I'm picking up on more intentional or if not, lore-compatible, examples of John Hammond's "spare no expense" going towards as much the illusion of control as any actual innovations/control.
Are they columns in the building load-bearing? You know, the ones with giant chunks chipped out to be more aesthetic and look like fossil digging work.
Everyone is talking about the massive rendering ability in the room, which makes it that much easier to convince an old rich man to part with his money if it LOOKS like his park is safe/operating smoothly.
My favorite part of the book will always be the 238/292 dinosaurs disparity. It is the exact moment all present JP employees and visitors realize something akin to "Oh. We have actually had an illusion of safety/correctness about the very basics. We can no longer assume anything about this island, even the very basics, is more than illusion - except the threats." At no point after stepping on this island is anyone not in danger.
When I watched Jurassic Park when it came out, I got so enamored with the computers in the movie, especially the SGI, that I adjusted the looks of our DOS GUI library[1] so it would look more like it. (I had already a liking to OSF/Motif then)
We just watched this movie last night (as a tribute to Sam Neill). I loved all the SGI hardware. Although the Irix FSN file explorer scene made me cring. It was excurciating watching Lex navigate. On that era of hardware, midnight commander would have been my jam. (or honestly `ls` just like it is now). I did love seeing Dennis pounding on that Apple ADB keyboard (even though there was no way that'd be hooked to an SGI Indy unless he did serious work). Just for giggles, I hit up eBay to see what a Quadra 700 was going for. Wait, WHAT??? 1500 - 2500 USD??? For an antique that will do nothing all that useful? Wow. Wish I still had my Macintosh SE that I could sell to put my kid through college....
I re-read the book recently and it was really fun to read about the tech now. The descriptions of how difficult it was to build a database that could handle storing 3bil base pairs, which is trivia now. Probably the most sci-fi part of the book, they had image recognition tech so advanced it could track individual dinosaurs from arbitrary video angles alone.
Also, Nedry got absolutely shafted by Hammond in the book. Nedry describing the difficultly in building a complex system with minimal requirements had me sympathizing, lol.
I work as a film prop master so this is fun to read and imagine my work being celebrated 30 years down the line. The art department will often lean heavily on me for tech-related set pieces because I have a CS degree. This article is a testament to the fantastic work of production designer Rick Carter, set decorator Jackie Carr, and prop master Jerry Moss.
The control room in Jurassic Park was honestly beautiful - and something about those shaving cream cans really crystallized the aesthetic for me, weirdly. I had no idea that it was taken so seriously, I just remember thinking "damn, that's actually pretty realistic" when I re-watched the movie a few years ago.
> This machine specs reminds me of how awful '90s laptop screens, based on a passive matrix, were. Definitely something I don't miss from that era.
While the 1991 Apple PowerBook 100 did have a passive matrix display, the machine it was based on, the Macintosh Portable from 1989, had a crisp active matrix running at 640×400 (even higher resolution than the compact Macintosh desktops with 512×342).
Interestingly Apple tasked Sony with designing the PowerBook 100 by taking the Macintosh Portable and slimming it down as much as possible. They shaved over 10lbs by moving away from the lead acid battery, dropping the floppy drive, and moving to a passive matrix display.
How am I only now seeing that Nedry's SGI monitor had a picture of J. Robert Oppenheimer on it with a scrawled message, "Beginning of Baby Boom"?
What an oddly specific Easter egg.
Also, SGI keyboards never used ADB. Indigo-era SGIs used a mini-DIN keyboard/mouse, but it was proprietary. They were PS/2 starting with the Indigo2 and Indy.
I think Fabien is misinterpreting the part which he sees as "video conferencing." Nedry is talking to a guy on a regular phone line. He's just watching a security camera feed from the dock where the guy is.
A clone of fsn, fsv (File System Visualizer) is available and works on modern Linux.
Quite a fun little tool to visualise your storage.
"There is a continuity error in the movie. See how the stack of PLI is facing left in this early shot."
It occurs to me that Arnold would be likely to turn these to face him when sitting at Nedry's desk (unless we see a shot of him going to sit and they already face forward). It'd obviously be part of the review of undoing Nedry's lockout to see if the backups are working (if I understand the point of the machines).
I was five years old when I saw this movie and it blew my mind and now work in tech and read Hacker News for deepest of the deep dives into nonsense like this. So yeah, I devoured this entire article. Thanks!
It feels like 1990s movies were the heaviest on computers/gadgets. Jurassic Park has a programmer as a main character, GoldenEye has two.
> Since John Hammond "spared no expense", it is fair to say he picked 1GiB version at $3,598 a piece. That would give them 7 GiB of storage for a 2026 equivalent of $33,223.70. In 2026, 7 GiB of HDD would cost $0.49.
Did anyone ever try to estimate storage inflation across time? 7GiB could be one or two pc games in 2026, in 1992 one games likely was 1.4MB.
Biggest lesson of Jurassic Park: Don't hire only one sysadmin
I feel like there should be an online museum dedicated to reproducing the graphics in movies, as faithfully as possible.
Especially awesome if film-makers started DONATING their video assets to the museum.
It had a Motorola 68000 processor at 16 MHz, 2–8 megabytes (MB) of RAM, a 9-inch (23 cm) monochrome backlit liquid-crystal display (LCD) with 640 × 400 pixel resolution, and the System 7.0.1 operating system.
A single mp3 would be more than the entire memory, let that sink in :)
I randomly came across a YouTube video [1] on the history of After Effects that I found really interesting. Seems as if there is quite a bit of evidence that the Nedry animation was done with an early preview.
If people like this post, they will probably like the below post about the typography used in the movie Alien.
The site has typography analysis from several other scifi films too.
Generally full marks on realism, but I have to ask: Is a combination of SGI and old school macs a sensible platform for running a park? I guess if the macs can get on an appropriate network then they could at least send control commands, but they feel like an odd fit compared to the UNIX™ boxes.
According to the post, the first computer was in their trailer, but there's an earlier scene where they're using a monitor to view the raptor bones in a tent at the dig site. Not sure if that counts but I'd like to have learned more about that device.
The attention to detail spent here was what sparked my original interest in computers which inevitably led to my career. as a young man, watching this movie I was amazed that one man and a bunch of computers could unleash such mayhem.
Minor typo fix "SuperMach" > "SuperMatch
Hey Fabien! It doesn't look like the link for this article is on your main page. I love your posts and check the main page frequently each week; I totally missed it until I saw it here.
fabiensanglard - thanks for all the wonderful posts about.. everything! While I started reading your blog when it was more focused on old games and C development, I still check it from time to time. I'm always blown away by the level of details you manage to dig up and present - no matter the subject.
This is why I love the internet! Thank you to the author for taking the time!
And I was worried I wasn't going to have anything to read tonight.
This is so cool that we need a new HN feature for this like a 'gold bar'. Dang can you build this?
I used to have a script running that whenever somebody failed to SSH into my laptop, it would blurt out "I hate this hacker crap" [1]. I had mostly forgotten about it until I was at a conference and it starts going off - followed by a guy nobody knew quickly leaving.
Another detail worth mentioning via Taniwha [1] was Supermac had an engineer on set and configured the graphics cards to run the monitors at 24hz so they wouldn't have any banding when filmed.
Is there a behind the scenes detail on Jurassic Park branding and logo? I love how well they planned it ahead and wove that into every thing we see across the park.
> The filename whte_rbt.obj is not mentioned in the movie
From 1:09:50 – 1:10:13, we join Arnold as he describes Nedry's methods to Sadler, Hammond and Muldoon.
At 1:10:00, Ray Arnold mentions the whte_rbt.obj — whatever it did, it did it all.
This is great - lovely detail.
This the the type of content I live for!
In the 2nd image (clearest) and other images, there appears to be some binary encoding in red. It must encode something!
And yet again I am reminded of how SGI was so far ahead of the graphics game and yet was absolutely demolished because others could see the potential for domestic add-on cards when SGI was focusing on entire work stations.
3DFX and Nvidia ultimately put them out of business.
It's a shame that HPE doesn't make graphics workstations any more.
This is incredibly insightful!
Another good Jurassic Park content is this filming locations video. Almost everything can still be visited today https://youtu.be/34r8Ypxzkk4
This post is the definition of why I like HN. You never know what random fun and interesting post will make it's way here.

The head of frogdesign (Hartmut Esslinger) ended up running into Spielberg on a plane and showed it to him. The one in the movie is an original mockup.
