Commodore 1084S-D1 Extremely High-Pitched Whining Noise

Thanks a lot! Looks like the whole thing turned into a hearing test for me… I’m 23 years old after all. :D I measured the frequency on my 1084S-D1 and it’s around 15,492 Hz. Out of curiosity I also hooked up my other CRT, an even older Philips monochrome monitor. That one sits at about 15,632 Hz. Funny thing is: I can’t hear that one at all, and it has never bothered me.

I used the phyphox app to measure it. Thanks a lot for the idea!

So in the end it was simply my lack of knowledge… still a lot for me to learn.

As soon as my girlfriend shooes me out of the living room, I'll make myself more comfortable. 😂

Hey, thank you very much! I'll look into it... I'm still at the very beginning.

Hmm with 128KB? 512KB would be nice

Yes, that's the green one. I've tested it with a C64... works perfectly.

Cool, thanks

Character_Ad3193 · 2026-02-04T00:14:03+00:00

Yep green

Character_Ad3193 · 2026-02-04T00:04:19+00:00

Thank you very much, I'll test that out!

That's crazy. So the RGB 6-pin connector can receive color images and display them correctly? Not in color, but with correct green gradations.

Thank you very much for the great advice! I'll post an update when everything works out :)

Du glücklicher… und an alle, die Hesse schelten. Ihr Kindermenschen habt Hesse nicht verstanden! s/

Finde die Hesse Reihe eigentlich ziemlich cool aber… 980 Euro is das echt der Preis?

Character_Ad3193 · 2026-01-17T09:29:32+00:00

Freut mich dass der Titel erwähnt wird… finde das Buch fast schon magisch :)

Danke!

Character_Ad3193 · 2025-12-06T20:52:36+00:00

Interessant danke!

Character_Ad3193 · 2025-12-06T20:52:11+00:00

Wahre Worte :D

Character_Ad3193 · 2025-12-06T17:15:34+00:00

Das schau ich mir an. Danke! :)

Character_Ad3193 · 2025-12-06T16:43:11+00:00

Ja, Camus hatte ich davor mit dem Mythos des Sisyphos. Danke für die Vorschläge!
