Voltages at
IC106
to
806 were with
B-type IC's
voltages
with C-type IC's
will be almost
the same.
Voltages
at
the ROM(IC4
in the cpu-pcb)
were with
an
I-version,
voltages
with
a
K-varsion
ROM will
be almost the
same.
The unit was
in
the PI
program mode with
no key
function(No
function
change after
the power
SW
was
"ON").
(D

indications were
for DC
voltages with
pulses, voltage
may
vary
by
the wave forms.
Voltage indication related
with
FLD D3
may
vary
with
