Weird find, QNX, and cooling

Hey, any industrial controller collectors out there? I didn't think so. I just picked up an exceedingly cool 486 box from around 1993 with a touch-screen LCD and ethernet. The entire machine is about the size of an Amiga box, but it's in a black hermetically sealed magnesium case. It's running QNX 4.11, and root didn't have a password (woohoo!). The Li battery was starting to ooze corrosive juices onto the CPU, but other than that, it's in primo shape. I have some stupid questions: Was there a GUI for this version of QNX? I can't find one, nor anything that exploits the touch screen on this box. There are three fans inside the box, but it's sealed. I always thought that fans worked by exchanging hot air for cooler air. What good are fans inside a sealed box? Long shot: the display blanks after a few minutes, and hitting a key (it has a keyboard port) or touching the screen doesn't unblank it. Any guesses on how to wake it back up (BTW, there's no power switch on this thing -- it wants to be on *all* the time). -- Doug
