when the disk is not open, to give
better temperature control. Turned
off fan, put in slow read/write
self test.

Replaced 1562 - h[O V?] reference supply
in type 30 scope B14. The wavy lines
seemed to be due to them getting out or
the -10 V supply to position [ducs?]. It
was intermittent and disappeared before the
replacement, so it is not certain the 1562
was the cause.

There remains a bug in the type 30
that causes defocusing of the spot at
various places. It does not seem synced
with the display rep rate which is
synced with the line.
