Portal 'Want You Gone' on Old Computers

This is my halfhearted attempt at creating the portal 2 ending on ancient computers.

Computers in this video are:
IBM PC-XT - 1983
Compaq Portable - 1984
Compaq SLT-386 - 1989
Compaq LTE Elite 4/75CX - 1994
The program used to create this was Microsoft qbasic for ms-dos. The computers were manually synced.

More information:
PC compatible computers of this era did not normally include sound hardware, and the only way to produce sound was through the PC speaker. The PC speaker is normally only capable of playing a single tone at a time, so in order to produce harmony I used four computers, one for each voice. Programming the song was done by manually typing in the sequence of tones in each computer, then starting the four different programs at the same time. The beeping at the beginning is to help me sequence the start of the programs with each other.

Cave: "This is fantastic. I want whoever invented that jingle to get a raise, and I want all the people who programmed this to get raises as well. I am too happy, it's perfect."

I actually startled at the cut off.. i was prepared to listen to the whole song this was phenomenal!

[gomango]

The urge to find old PCs anywhere and do cool stuff like this to them

[catfood]

Did...did you just use the fricken bios beeper as a speaker?!? I love it. Please do more.

[DamianBordadLopez]

Out of sync? Sucks? Mate, this is amazing! Where's the full version?

[rederratic]

This is so cool! The aesthetic from the old computers is perfect

[PaullyBoiPlays]

what my parents see when I just restart the computer

[lyricfoilasleep]

Us in the dystopian future hacking our work computers to try and get a fraction of some humanity.

this is incredible, give yourself more credit

[Otto_Malkus]

I love this! Its so amazing how you can do these sorts of things! Astounding! I love the song too, the fact that Po2 uses similar computers just makes this so much better. Amazing song, amazing concept and amazing execution! You earned a subscriber!

[TradieTrev]

Thank you algorithm for finding this gem!

Man that massive one in the bottom center brings back some memories. Hard to believe Compaq called that portable. Great work.

Why it gave me an extreme feeling of nostalgia? More than the original song itself

[SimonsAstronomy]

This just sounds better on old computers

[infini_T]

I love the noises in my left ear!!!! But really it makes it feel like something is in my ear

[futuristicentity]

And now modern society treats these machines like a joke so much nostalgia going on I can't believe it's already 5 years after this persons video upload.

[DaRichMan]

Not gonna lie. I was really disappointed when it cut off at the end. I want more. Please.

[RaccLewi]

yo this is the coolest thing i've seen since the real life prop gun from gmod, I love the portal series and this hit home for me.

[Ambush]

It's so nice to hear computers sing

I can just see Doug Rattmann just finding one of these computers, playing this on repeat, as just a breather from surviving the facility from a while.
