First computer I had was a DEC Rainbow. Had probably as much power as my wristwatch does today (if not less), stood a meter off the floor, had 2 5.25 drives...
I remember the day my Dad brought home an RGB monitor for it. AN RGB MONITOR! It had one input for red, one for blue, one for green. It was amazing. There was a frigen cool game called SCRAM. You were a guy in zero G who had to get down to the reactor and lower all 4 control rods. You have to navigate through about 5 screens of travel. You basicly entered the screen at the top, then had to get to the airlock at the bottom the cycle it to get to the next stage.
Problem was that the reactor kept getting hotter and hotter. And acceleration used up thruster power. You COULD on each screen go to a station to dump a heep of coolent into the reactor to take it back down. Or dock at a fuel station to recharge your thruster power. If you ran out of thruster power, your ability to accelerate was WAY down and you would bounce all over the place...
So the game was a trick of being able to easily move down each level with a minimum of correction as fat as possible, alternating one level to use the thruster recharge and input coolent on the next. If you had to go to both on one level, you would use up way too much time...
God DAMN that was a cool game though!
EDIT
Ahh this is the guy.

Unfortunantly while it did use a Dos interface, it wasn't bassed on the 8086 and you couldn't run IBM bassed programs on it.
Then we got a VAXmate and it WAS able to and I was thus happy
