<DIV><FONT color=#000000 size=2 face=Arial>The blower under the half-inch
baseplate feeds filtered air into the headwheel motor for cooling. If your head
takes high pressure air for the air-bearing (unlikely, you thought it was a ball
bearing head), the connection is a nipple on the lower rear of the machine.
Noisy compressors were kept away from the operators. There might be a small
vacuum pump in the lower deck for the tape guide, or someone could have adapted
a venturi system and removed the rotating vacuum pump.</FONT></DIV>
