Zenith Data Systems Z-Sport 420s

I got this scrap vintage Notebook as a gift from a friend, apparently something he used on his lab at a Physics University in early 90s, sadly the LCD screen has melted and the battery is dead, but I have no idea about the conditions of all ther components yet.
After some research, apparently this usually came with a 20MHz Intel i486SX, and non-removable 4MB of RAM, which you could upgrade up to 12MB.
It comes with a really nice mechanical keyboard, sadly the mouse wasn't found with it, and since it predates touchpads if this worked I'd be stuck to keyboard use only on DOS.
It's in a pretty bad shape overall and I probably won't be able to put it back to work again, still makes a nice addition to a collection, not sure what I'm gonna do with it.
