Open Arena. A game I sometimes play to kill time… and enemies 🙂
Running low on root disk space
Deleted some old kernel modules, from “/usr/lib/modules”
PDP-1 spacewar
I got it to work on the PDP-10. But this is the one I really wanted to see. The original 1962 video game on the PDP-1 at MIT. The PDP-10 version is cool but not the original, with “the needle” and “the wedge”. It certainly was one of the first video games. It was out 10 years before Pong in 1972, an the Magnavox Odyssey the first consumer video game. I had one, only because I had wonderful parents… not the very first model, but not long after.
I tried to get spacewar to run under an emulated PDP-1 in simh… and I did. But it was so slow that it was unplayable. You basically boot from paper tape, which is a spacewar.rim file. I think I got it here.
I also tried and failed, to get it to run under mame. It took some trial an error to figure out how it expected the directory to be, but I finally came to the conclusion that I needed to put a zip file… containing spacewar.zip (containing spacewar.rim) into /usr/share/games/mame/roms/pdp1_ptp/. Because when I did that it complained about the length of spacewar.rim, so I knew it found it. Where previously before I created the pdp1_ptp subdirectory (I got this info from /usr/share/games/mame/hash/pdp1_ptp.xml) and put the zip file into it, it just said it couldn’t find it.
Actually the only one that would work flawlessly was the javascript one that ran in a browser., that I talk about here.
It seems odd that the best PDP-1 version is a javascript one.
I made a couple videos concerning ITS
Right now they’re just for me although they could be used to create an ITS howto. The first one is startup, login, create directory, create file in that directory and shutdown. The second video was to show the playing of spcwar (Space War). But I also added some basic programming info. I do think I’ll do a quick edit of the first video to compress the exciting 5 minute shutdown.
The Soul Of A New Machine
I guess I need to post this because I keep losing it. It was a great book the best I remember. It was about the Data General Eclipse MV/8000 computer, Data General built. It won a Pulitzer Prize for General Non-Fiction.
Controlling the ship in spcwar on the PDP-10
SpaceWar is actually my primary interest in the ITS on the PDP-10. I talk more about it here. I don’t have much interest in doing actual work on this obscure OS.
I asked the PiDP-10 google group, if anyone knew how to play spacwar running in ITS. And Lars Brinkhoff replied “To play Spacewar, you need to plug in USB game controllers. The now-regular PlayStation type.”
So I dug out my old Logitech WingMan Precision Gamepad, and it seems to work fine!

Running spcwar on ITS
Lars Brinkhoff
2:35 AM (5 hours ago)
to PiDP-10
Forgot to say, you can adjust the number of stars and players. Type ^Z to stop the game, $^K to load symbols and then NSUNS/x or NSHIPS/x to adjust parameters. X is a number, 1-3 for stars, 1-4 for players. Restart with $P.
My computer started beeping
I actually fell asleep at the keyboard, and was awakened by beeping. Went to all my virtual desktops and didn’t see anything running. I closed my browser because I wondered if it might be coming from one of the tabs. That didn’t help. I almost re-booted. Decided to look at running processes and saw gnome-clocks. Killed the process and it stopped. Looked at ‘clocks’ app and there was an alarm for 10:15PM. So as a test, I set an alarm for one min past now. Sure enough it started making the same repeating beeping noise. So I set it again and closed the app. Sure enough is started beeping. That’s cool and useful, but I always assumed the app needed to be opened. I know that wouldn’t be nearly as useful, but that’s what I thought. I have other apps that need to run but if I close them thy just go to the system tray where you can see them, so you realize they’re actually still running. But gnome-clocks doesn’t do that so I assumed, it’s not running if you close it. I also realized (now in hindsight) I could have stopped it by responding to a notification in the system tray at the bottom. But I don’t remember setting an alarm. I could have also given it a name like “Go to bed”. But surely I would have remembered doing that. The only logical explanation is I had set it in the past then earlier when I used the “Timer”, which I often do for a short reminder and somehow I turned on the “Alarm”. I use the “Timer” for a quick reminder, for example, to let my dog back in, in 10 minutes. Because I can easily get lost in what I’m doing. I only use the “Timer” for short reminders where I’ll be sitting at my computer, because it’s just one quick tone, and if I walked away, I could easily miss it. Where as the alarm repeats constantly.
