Dear Vogons,
does anybody can advice if there is existing ISA soundcard which has PLCC socket and can accomodate CS9236 ? I found out that those card should be based on Crystal chip also , but i cannot find any though..
Anybody can advice ?
Than you

I have seen a lot of ISA soundcards, also crystal based ones - and never have seen one with a PLCC socket. But I once had a Fujitsu Siemens Mainboard that came with such a socket to add a Crystal wavetable if needed.

Many crystal soundcards have unpopulated solderpoints for wavetable ICs so maybe a skilled person can add this?
Here is a video of one of my crystal cards - in the top left corner near to the wavetable header you can see a place that might get upgraded with such a socket. But who knows which other parts are needed as well..

3 caps and a transistor?
ah, there seems to be an extra resistor on R15 too

could certainly just install a socket on this card.

Yes I see Crystal cards with a socket in that spot on eBay from time to time - the socket is always empty, from what I've seen anyway. I've always wondered if you can just put a CS9236 in and it will work but I've never bought one to try it.

EDIT: there's a few cards listed right now actually, e.g. https://www.ebay.com/itm/304844637300
