I always have dreams of that kind f things happening like that I'm going to go to a garage sale or something and there going to have amazing equipment and not know what it's work and just sell it to me ridiculously cheap. But, to this day I've never been lucky enough for this to happen.

Just so you can see again and to help you fathom how cool it is that you got it, and so cheap!!!
This keyboard also has a sampler in it. It's an awesome keyboard, I had fun playing with it at guitar center.
At first, you should just mess around with it, and then as you run into things you don't know how to do you need to definitely refer to the manual . I think you should still try to even hook them up midi. Either one could be the master or slave. The master controls the slave.
You might get some help from this article:

Also, you can just hook them both up into a mix onto different channels to be able to play and hear them both at the same time if you wanted too. That's what I would do with these.
Do you already have a mixer?
well Congratz!!!!!
