on, SAR and TRACK Register are counting
as though the unit were off line and in
band repeat, Band = 16₁₀. WCMA of
the IOP = (777600)035671. BR =
(654600)0. SR = (0)1. The
original DATAO given to the IOP was
(777600)35667. This location
contained (and still contains) (21)21.
location 35670 contains (654644)0.
35671 contains (45600)0. None
of these locations have parity errors
(according to the 169). Pushing I/O
reset stopped the Disk. Further attempts
seem to show that the IOP is incapable of
reading from core without getting a parity
error. I was not able to reproduce the
above effect, however. In further experimenting
it happened again. Doing a CONO 10,0
does not stop the disk, but doing a
DATAO 10, [0] does.
