The IC's you need will have either 8 pins or 14 pins on them.

Although digital IC's and EPROM's are fun to work with too !!!

That's exciting!
I remember that one of the ICs is used to produce sound, I don't remember which one.
Tomorrow I'll try to grab more ICs at school, I didn't pick many because I didn't know much about their applications in sound. There are much more where I picked them, in a dusted glass jar hidden in a corner.

You can just google the numbers and find the data sheets on just about any IC or any other part.

The AY-3-8910A was a neat little sound generator.
I have one of those around here that I never even hooked up.
They are quite rare to find now and are actually sought after by many.

You probably have all of the workings of a nice little single board computer.
I have had many Z-80 systems back in the day that ran CP-M and MSBASIC.

Here is the data sheet on the sound chip,

Great find !!!
