Found the bug in my scope!

I was moving my scope around to another bench when I heard something loose inside. Of course, thinking something was broken I slid the cover off and found this guy. He was the problem of the loose thing and I myself have found an electronics bug.

A piece in electronic sound synthesis history

A piece in electronic sound synthesis history

I thought to share with you this chip I desoldered from an old Creative sound card from the nineties. It's a YMF262, and can be considered a piece of history in electronic sound synthesis for music. Made by Yamaha in 1994 it's an Operator type L, shortened in OPL, and this is an OPL3, the latest version of this series before it was superseeded by the ESFM technology. For those who are no longer young like me this is a remainder of how music sounded from the computers of the era.

In this Wikipedia page there is the whole history plus some sample sounds: https://en.wikipedia.org/wiki/Yamaha_OPL

The chip I desoldered is likely still working, even though I have no projects to use it besides taking a nice picture of it.
