[sdiy] YAMAHA IG0015xx IC's

[Bert]

Hi

does anybody know something about the numbers of the yamaha ic's or wher i
can find this info.

At most numbers there are two numbers  an IG00xxx number and m516xxx number

There are also numbers which are slighly different. My question is

is the IG00152 the same as the IG001520. (the second number at the IG00152
is M51622P and the second number at the IG001520 is M51622B). I need one for
the CS50. If somebody know where to get the IG00152 it will help also.
