One of the things I did with a Coco3 was install a fan inside the case 
below the keyboard. I cut a hole in the bottom the size of a box fan, 
glued mosquito screening over the hole, and attached a small box fan. 
The fan along with a small regulated power supply draws power from the 
Coco3. The air flow is in at the bottom and out at the top. Somewhat 
noisy over a dead silent Coco3 but it does keep it cool.
