...and I have installed Picasso 96 2.1 (I think) and have gotten class act and the new icons on disk and will be installing them tomorrow.
It came with OS 3.9 installed, but doesn't have a CD ROM drive any more.
Do not install Classact if you're going to keep using OS 3.9. It has its own, newer, version of Classact called Reaction. OS 3.9 will break if you install the older Classact on top of it.
It also has a wire attached to the back of the motherboard that I'm not certain what it does.
That's likely to be the /INT2 modification.
