Title: PMI DMX88 Mux
Post by: obsoletemachines on April 12, 2015, 09:08:46 AM
hi, has anyone got a source for this chip?

I have a drumulator which has its fair share of problems.  Reset was out on CPU so i replaced CA3086.  Then the Rom was scrambled so i obtained a fresh Rom.  Then the sounds were distorted so i attended to the TL084 buffer op amps.  Now i get all the sounds but they are in the wrong places, eg. BD is comes out of snare.  I think it has to be Demux , levels etc are fine.

I'm nearly home and just wish to bring this over the finishing line.  So, if anyone can help on this chip i would be grateful, eternally.

There seem to be pin compatible alternatives, so I will try them and report back.
