Computer Log

I heard this music combined with old videos from the past, on Instagram. And I immediately thought that it really did evoke a sense of nostalgia and sadness. Luckily someone in the comments said the name… Aquatic Ambience. So I looked it up on YouTube and even without old videos the comments were almost all about a sense of nostalgia. I mean there are songs from my past that may evoke a sense of nostalgia to me and people of my age… but not necessarily other age groups. But there’s something about this music that seem to effect me and people much younger than me the same way. Older than me? I’m not sure. It’s just music… no lyrics. Since I have such fond memories of vintage computers and my past computer employment. It just makes sense to add it here.

This version has been slowed and reverb added. I like it too.

You could also say this evokes a sense of nostalgia, but not sadness and melancholy. Unlike “Aquatic Ambience”… it’s immediately recognizable.

I think back to the days I was living at home, and taking computer classes at school, and was explaining a computer problem to my mom. She had no idea what I was talking about, but would patiently listen to me, and in the process of explaining it to her I would often, figure out the solution. Thanks mom. I miss you, and those days.

There is also, a definite computer aspect to it… according to Wikipedia… it was composed by David Wise for the Super Nintendo Entertainment System (SNES), video game Donkey Kong Country (1994).

I was thinking, I had it for the N64, but all the box art I see is for the SNES. I looked and I found Donkey Kong for the N64 (below), but not Donkey Kong Country. Also I saw I had SNES games, which was a shock, because I completely forgot I had a SNES.

OK, I checked and I do have Donkey Kong Country for the SNES. I also have versions 2 and 3.

I won’t post the links here, but there are many other YouTube videos talking about this. For example “The Most Emotional Video Game Music in the Unlikeliest of Places”. “The Genius Of Donkey Kong Country’s Music” and “Music Theory: Mining Melancholy | Donkey Kong Country 2”.

This has happened for a long time. If I see a video on my main suggestion page, I always right click and open link in new tab. But occasionally it will also open it in my main YouTube home suggestion page. The main problem with this is if I click the back button (not the home button) to return. It doesn’t return to where I was, well actually it tries to give that impression, for example if I was half way down the suggestion page… it returns half way down the suggestion page. Except all the suggestions are new, so I’m not picking up where I left off. Meaning there may be many videos above where I now am, that I might be interested in. It’s the same thing If I return after I restart the browser or the computer.

If you’re going to reload all new suggestions… just return to the top of the page, because you’re not resuming, where I was!

Here! Lot of manuals also. Nice site in general for DG Novas.

Just for the heck of it…

I did make nova in Open Simh

Got the RDOS disk image, here. I assume this is probably a very common OS for DG Nova users to run. However it’s not the OS that my company ran on our DG Nova 3. We ran a very obscure OS called Blis/COBOL. I’ve talked about this before.. an OS, written in COBOL!

Found some simh usage info, here.

And here we are…

I thought this was interesting. Five billion in 1964. By contrast the Boeing 747 cost 2 billion in 1970.

The 3rd and final problem.

make -C tools/cbridge
make[1]: Entering directory '/home/bill/Downloads/Computers/Emulation/simh/PDP-10/ITS/its/tools/cbridge'
cc -c -g -o cbridge.o cbridge.c
In file included from cbridge.c:96:
cbridge.h:90:10: fatal error: openssl/ssl.h: No such file or directory

compilation terminated.

This was fixed by…

sudo apt-get install libssl-dev

At last it finished without bombing!

Yes the info that I could resume that step without rebuilding… worked. But the operation of ITS didn’t seem right. So I reran the whole thing again and it bombed further down.

I mean the 2 hr step that failing follows, a previous step that says “The repo comes with a handy script to install required dependencies”. So evidently that’s not true.

Package SDL2_image was not found in the pkg-config search path.
Perhaps you should add the directory containing `SDL2_image.pc'
to the PKG_CONFIG_PATH environment variable
No package 'SDL2_image' found
Package SDL2_image was not found in the pkg-config search path.
Perhaps you should add the directory containing `SDL2_image.pc'

    4 | #include <SDL2/SDL_image.h>
      |          ^~~~~~~~~~~~~~~~~~
compilation terminated.

So I found this suggestion on stack overflow…

apt install libsdl2-image-dev

It’s so confusing today. I jumped through similar hoops, in the early Slack days. Things to look at…

PKG_CONFIG_PATH, SDL2_image.pc, libsdl2

I had my day in the sun where I had to (and was paid to) do similar things on DEC & IBM hardware. And it was necessary in the early Linux days… if you wanted things to work. Now I have very little interest in chasing down solutions. I just want things to work. Especially when your told run this and it will take care of dependency issues.

OK that seemed to fix that problem.

On to the next problem…

At this point the instructions say “You are now ready to log in, so type CTRLZ“. Log in where… an administrator account?

It’s early AM, so I’ll just force the system down, and do further research later.

Opened github issue.

fatal error: SDL_net.h: No such file or directory #2296

eswenson1 commented that I needed to…

sudo apt install libsdl2-net-dev

Also responded “You don’t have to start over. You can just install sdl2 and then change directories to the its/tools/tv11 directory and make that project.”

So I did (which saved me 2 hrs)…

bill@bill-MS-7B79:~/Downloads/Computers/Emulation/simh/PDP-10/ITS/its$ make -C tools/tv11/tvcon

So glad this is automated! Got files and procedures from github.

make clean all EMULATOR=pdp10-ka

A lot of text scrolls by on the screen… it takes quite a long time to build the dependencies. And by a long time, I mean around 2 hours. Where’s that turbo button when you need it? A big reason it’s so slow is because much of the work is in the emulator, “KA-10 simulator Open SIMH V4.1-0 Current”. I think I saw spcwar scroll by on the screen. A few times you wonder if it’s stuck. But by habit, I run a system monitor and I could see pdp10ka… working.

sudo apt-get install libsdl-net1.2-dev (didn't work)

Perhaps I should have...
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libsdl2-dev (ALREADY INSTALLED)
Next...
sudo apt install libsdl1.2-dev libsdl-net1.2-dev

Start again at 10:24AM. Ran 2 hrs. Then got the same error.
