5100 Termination Problem
Process check
and/or
halts might be caused by a
defective printer adapter card in the 5103 printer.
5100
5103
or
Terminator
5106.
When a total system is connected, the termination is
done by the printer adapter card in the 5103 printer.
When only the auxiliary drive (5106) is connected, the
termination is done by the terminator assembly attached
to
the rear
of
the 5106.
Be
sure the terminator is
mounted in the
I/O
connector and
not
in
the storage
location.

not
able

center the

for
the 64K machines.
If
the
B/M
5572571 is not installed, order
it
from
Mechanicsburg.
