Sample cartridge

Hi all,

When I was going through my stuff, I found an Alphasys Sample Cartridge.
I used to record some TV series themes and it was fun doing it.

I don't know if the quality has become worse, but now when I record, I find it horific.
Maybe I'm using the wrong software. Maybe some has some good suggestions for better software?

Also, I am curious if the sample cartridge can be updated?
Since I'm no expert in the matter and second all the IC's markings are gone, I have no clue were to begin.

I made some pictures.
