Had a burst of parity errors from
AMPEX CORE

[printout with annotations]

Restarted at 140, zeroed ampex
core. for 30 min, no errors. Ran
BLTST for 30 min in ampex core, no errors.
The programs running in Ampex core were
loaded by loader, which clears fore first
and [?]SP which initilizes core, so
the errors were not left over from the
past. Apparently something hits in bursts.

SRR

--> I have a suspicion that there is a
mechanical difficulty.
