I also keep my hard disk well inflated. I just take it down to the gas
station and connect the hose to the air hole and inflate it to 35psi cold.
Being serious (Ha!) for a moment, the Micropolis 1200 HDAs (as used in
PERQ 2T1s Tektronix 8560s, etc) has a Schrader-type valve on it. It has
the normal screw-off cap and what looks like a standard vavle core in it.
I have no idea what it's for. The HDA cannot be presurised in normal use,
there is a breather filter. One suggestio nwas that clean ar was squred
in there when the HDA was made, forcing any resitual dust onto the
brether filter. Any other ideas?
