Retro Computing at the Movies

Streaming and the wide availability of video on the Internet have made it easier than ever to find and watch material that was unavailable or just hard to find for many years. I a previous bLog article, I covered YouTube channels that are providing archival first person computer history videos.  But Hollywood entertainment is another culturally relavant source.  Here are several feature length Hollywood movies with connections to computing and computer history.

The films in this article fall into two categories.  The first set of films from before Y2K show peoples attitudes towards computing machines and their interactions with them.  The second group of films are more modern movies post Y2K which have historical computing as a theme of the movie.

Older Films (Pre Y2K)

Desk Set (1957) with Spencer Tracy and Katherine Hepburn was fun, I saw this film for the first time last year.  Two of the things that stood out to me were the uncertainties the workers had about how computer automation would affect their jobs and a repetition of the pattern where new automation solutions do not live up to the hype, at least in the short term.  An enjoyable film and one I'd recommend.

The films Twilight's Last Gleaming (1977) and Damnation Alley (1977)  both show inside of a Cold-War Atlas missile silo.  These were of interest to me since I'm a child of the cold war and the "What If" scenarios presented by these movies are definitely the main point.  But another thing caught my eye watching these films since these missile silos were controlled by a massive computer network called the SAGE Air Defense System (or its successor).  SAGE was designed and built during the cold war to try to prevent nuclear strikes from the USSR reaching the US.  If you are not familiar with the SAGE system, there's a fantastic talk from VCF 2025 that I'd recommend by Richard Thompson "The SAGE Air Defense System".  Richard points out in his talk that many of the SAGE control panels were saved and used a props in TV and film decades.  These appearance are cataloged on Mike Loewen's website here, and his catalog opens another whole world of media exploration in Film and TV shows.

What list of computer related films would be complete without a discussion of War Games (1983)?  This is the first film on my list that I remember watching at the time.  Back then I was more concerned about the threat of war but I was also interested in computers and computing.  Here's an interesting article about the tech used for making the film both on and off screen.  The main computer star of the show is the IMSAI 8080 computer, which has become quite expensive.  These pre-1977 machines didn't sell in the millions like an Apple II, but we can still have a similar experience with a modern replica kit built using a modern microcontroller.  I've got one of these kits on order, so stay tuned for a future bLog article on that topic.

Skipping ahead more than a decade, we have Hackers (1995).  I was in college at the time struggling to get an engineering degree and surrounded by computer geeks like me.  I didn't have a car in college and I didn't get out to the movies much which is just as well because we would not have found much to relate too in this film.  We weren't cool like the characters in the film.  It wasn't until studying the history of the Homebrew Computer Club and Hacker culture that I began to understand how computing was connected with the 60s counter culture on the West Coast.  This was not a significant part of my experience at a midwestern engineering school in the mid '90s.  However, rewatching the film recently was a fun opportunity for me to play the "Name that Computer" game.  Trying to figure out, is that an Apple PowerBook?  Is that a Toshiba Satellite or a Tecra? Which one?  I don't have a list from my last watch through.  Google search shows a detailed list, but I'm honestly not sure if you can tell just from shots in the film which computer is which, so I won't link that spoiler article here and let it ruin the fun of re-watching the film and playing "Name that Computer".

The only romantic comedy on todays list is You've got Mail (1998).  I recently rewatched the film as I was interested in seeing the portrayals of the early days of the Internet, but I'd forgotten (or never noticed when I was a kid) how problematic the Tom Hanks character's behavior (Joe) is.  But I watched the film so you don't have to.  Per the fantastic FAQ section on IMDB, Joe is using a "Desktop Replacment" IBM Thinkpad 770 and Kathleen is using an Apple Powerbook G3 250, the fastest of the Wallstreet machines.  I did enjoy the nostalgia remembering using the AOL free trial period and other dial up Internet experiences back in the day.

New Movies (Post Y2K)

The second category of films on this list is modern movie set back in time with computer themes.  When we look at modern films about the past sometimes we may learn more about our present attitudes than we do about the past, but these films are still interesting.

The next movie on my list is The Imitation Game (2014).  This is a film about Alan Turing and his team's work during WWII on code breaking.  I had my own doubts about the historical accuracy of this film after watching it.  One reviewer confirmed my suspicions says this is "... one of the most celebrated and most misleading historical movies ever".  I think most of us interested in computer history would be better off reading this article and skipping the film.

Silicon Cowboys (2016) was intriguing to me.  I've read and enjoyed Rod Canion's book "Open" about the founding of Compaq but I really didn't get into the TV Series "Halt and Catch Fire".  I remember one of the folks presenting about the history of Tandy computer saying "it was never that exciting" or something to that effect about that show.  But Silicon Cowboys is focused on what actually happened and that's still very exciting.

I've seeen The Social Network (2010) but it didn't make that big of an impression on me, so I'm not going to comment other than to say that I did watch it.  Hidden Figures (2016) is a feel-good movie where the underdogs overcome their challenges because of their patience and hard work.

What other films can you think of that have computing as a theme of the film?  Comment below or drop me an email, my address is in my blog Profile on the left side of the homepage.

Epson QX-10 - One of the Last CP/M Machines

The Epson QX-10 is a sleek looking design from the early 80's.  It is from the tail end of the CP/M Era and it's a really neat looking machine.  My experience with the QX-10 started when a friend was demonstrating his at a local Retro meet up hosted by Free Geek.  It turns out he had a second machine in need of repair and since he's already got a very nice one, I was able to acquire that second machine from him, thanks again, Steve!

I started working on this in the Fall of 2025 when I acquired the machine.  There was no cable included to attach the custom CRT to the base unit.  This cable brings both power and signals from the base unit to the CRT and so it's difficult to begin testing without that.  There is a replacement cable avaliable online, so I ordered one of those.  With the cable installed I could see that the machine was powering up to the "Insert Diskette" prompt.  This is a very good sign because it means that the processor is running and whatever diagnostic checks are built into the ROM are passing.

As with most CP/M machines that don't have a hard drive the A drive is used constantly to boot and run the machine, so the A drive often needs special attention.  This machine was no exception.  The floppy drives were manufactured by Epson themselves.  In order to maintain the sleek form factor of the machine they made these drives 1/3 height, not a standard 1/2 heigh drive, so these can not be easily replaced.  Knowing this I took my time removing the drives and cleaning and lubricating the mechanisms.  They were so jammed that I could not even insert or remove floppy disks from the mechanism.  With the floppy drives working, I could move on to the next phase of the repairs.

I made some floppy boot disks using my flux disk imaging setup that I've discussed before, but unfortunately my normal workflow did not work because these machines have a very unusual disk geometry so the first round of disks I created were not able to boot the machine properly.  But I did get far enough to type characters in to the screen and this is when I noticed the next challenge, the keyboard was not working.

This keyboard, the Epson Q603A, is a special one designed for the word processing software called ValDocs.  There is some good information on Deskthority about the keyboard.  This is a foam and foil keyboard, so I was not concerned because I've repaired several foam and foil boards over the years using the replacement kit from TexElec.  However, sadly, this board used a prototype switch with a much lower profile of foam and the normal replacement pads would cause the switches to remain pressed all the time.  I emailed TexElec about this and I was very happy to learn that they were already working on a low profile foam pad.  I got a set of these and installed them and the keyboard is working again as expected, one more step closer to getting this machine back on the road.

At this point because of my problems getting booted up and not have known good boot disks I stalled out on the project and set it aside.  But within a few weeks I saw a relevant post on the Vintage Computer Federation forums where I hang out, so I chimed in on there.  I received some great feedback about my disk imaging problem from one of the members there and I was able to create some new boot disks using a different starting point.  These boot disks worked and I could see that the Epson was fully booting up into an operating system.

Unfortunately, as often happens with Retro Computers, just when we think a project is ending, something else broke.  The CRT display starting rolling and I couldn't get the video to stabilize.  This CRT has only one adjustment for brightness on the outside so I took the case off to get inside.  I went through all the potentiometers on the circuit board and put Deoxit Fader Lube on them and cycled them back and forth.  I also did a careful inspection.  I was not able to identify anything wrong. After plugging everything back in it started working again.  I think there may be an intermittent connection with one of the sync signals so I'm going to try to isolate that to the Monitor side or the Computer side and maybe reflow the solder joints on those circuit boards.

But for now, the machine boots and runs, and it's time for me to explore one of the last and most modern looking of the CP/M machines.  I'm really glad to have this machine in the collection as it very much has the look of the era it came from...

Did you use CP/M back in the day?  Do you have memories of the Epson QX-10 or the Valdocs software?  If so leave a comment below, or drop me an email at my address in my profile, I'd love to hear about your experiences.
