Says QSI right on the ASIC....

Go to the groups.io forum qsiindustries

more likely a complete decoder with sound

I think that is "ISD" it is upside down.

Ahh, was looking on a smaller screen. I believe you are correct.

what about a better resolution and the other side? There are no part numbers?

Hi there,
ISD is the maker of "ChipCorder" IC's which record digital sounds. The early ones allowed 30 seconds or 1 minute of sound capture. I suspect its a very early sound card back to the 90's , may not be for locomotives - I have an ISD board that has a Steam Organ ( Carousel) sound on it !

It is definitely for locos, it works just fine with my 040. It was certainly a bargain basement card.
