Noisy Sound Blaster 2.0 in IBM PS/2 Model 25

[bladamson]

I just dropped a SB 2.0 into a PS/2 Model 25, and am getting a lot of logic noise on the output.

I think it may be related to video, mostly. Maybe they never expected someone to put a sound card in these things, and the internal video cable isn't adequately shielded...

Any tips on quieting these things down a little?

Thanks!

It's been 30 years; it's possible the electrolytic caps on the SB are drying out. Replacing them may help with the noise.
