Scope
(Memory modules

l
e:
CE-
151, 155, 15
9,
and
161.)
,
The P
C-l600
has been designed with
the
following versatile
features:
, . The most of
PC
-1500
BAS
IC software and
the
PC
·1500
hardware options are compatible with the PC·l600.
2. Advanced technology gives the
PC-
l 600 new features
not
available
on
the
PC 1500.
1·1. Compatibility with
the
PC
-
l500
BASIC
simulation mode
For compatibility with succeeding models, most of soft-
ware created
in
BASIC for the
PC
·
150D
can also run
o:n
the
PC
· 1600.
(a)
F
or
display in the simulation mode. a sing
le
line
on
the
bottom
of the display rows
is
subject for execution.
(b)
In
the
simulation mode, the same character codes
of
the
PC
-
150
0 are used.
(c)
Th
e
PC
-1600 must work with a
va
ri
ety of PC-1500
software programs
that
include an option control-
l
ing
system. and
the
PC
-1
6OO
system bus signals are
upper grade compatible with the
PC
-
l500
system bus.
(Consideration
is
given for
th
e use
of
the CE-
l50
. 158.
and 162E.)
(d) The slot signals are also upper grade compatible; this
allows the use of the
PC
-1500 memory mod
ul
e on
1he
PC

T
he
CE
·160 does not meet the upper grade com-
patibility test for software
that
uses the
REM
·' because
of a functional restriction on the
PC
·
l600
OPtional
printer
CE
·1600P, since the CE
·l50
has
two data
rec
order remote control
te
rminals (
RE
M-O
and REM-1).
1-2. Implementation
of
functions
that
were
not
feasible with
the
PC
-
1500
(a) Adoption
of
a 26-digit by 4-line alphanumeric L
CD
unit.
(b) Operation speed of the
PC·
1600
is
approx. 2.5 times
faster than
that
of the
PC·
1
500
as
a result of using the
general purpose microprocessor
(Z
·BO)
as
the main
CPU
.
(c)
Increased expansion module sl
ot
(two slots).
(d) Increased user memory area (
11
,834 Bytes user area
out
of
16KB basic RAM area).
Ie)
Im
plementation
of
the
EI
A.
conforming to the internal
RS-232C interface for communication.
(f)
Implementation of the system wake-up (modem phone
and timer started) and alarm functions.
(g)
Adoption
of
the analog input, bar code
re
ader input,
and external keyboard input interface.
(hi
Use
of the internal
opt
ical fiber
(SIOJ
interface.
