Thanks Marcus,
That would be great if you can dig up the data sheet on the MSM5232.
I am only missing the data sheets for the TG and the filter.
So if anyone out there has the data sheet (or knows a link to it) for
the following two chips please do help me out and send that
information along.
The TG is MSM5232. Hopefully Marcus will come through on that one. The
OKI documentation web page has a list showing the exact chip but when
you select it you get sent to a broken link (that's very frustrating).
I've emailed OKI but no response so far.
The filter chip part number is NJM2069. I get almost no results at all
when I search for that chip on the net. Maybe it was a Korg special
run or something.
Anyway, any help from anyone out there would be much appreciated.
Thanks,
Mike H.
