DESCRIPTION

1.1

GENERAL

The

Wang Model

2200

Advanced Programmable Calculator combines simple

keyboard

operation with

the

versatility

of

BASIC language programming,

a

compiler

language used

by

many larger scale computer systems.

The

Model

2200

is

essentially a single-user, noninterrupt, microprogrammed

system.

The

Wang BASIC compiler

is

interpretive,

operating

directly

on

user

text

and

saving

in RAM

where required.

A

fundamental

2200

system

incorporates

the

following:

a)

Central

Processor

Unit

I

FIGURE 1-11

b)

System Power Supply

IFIGURE

2216/2217/2223

FIGURE

1-5;

2220

FIGURE

1-6;

2226

The

CPU a) is

comprised

of ROM

(with

or

without software

options),

Arithmetic/Logic circuitry, system control logic,

I/O

interface (expanded

in

2219

chassis),

and

approximately 3.4K bytes

(expandable)

of

user-

available

RAM (4K

actual

RAM

space

for

smallest memory option)

. The CPU

constitutes

the

'heart'

of a

2200

system.

The

system power supply

is

either packaged within

the CPU

chassis

(2200

S,T)*,

or is

packaged separately

(2200

PS for A, B, and C CPU

chassis;

see

figure

2).

The

user terminal

is

comprised

of a

user input keyboard

(2215,

2222,

2223),

a 16

line/1024-character

video display which

is

available

in a

12

inch

(diagonal

measure) screen

(2216/2226)

or a 9

inch screen

(2220

console),

and a

Model

TD-24

digital

tape

cassette drive

(2217)

for

storage

and

retrieval

of

user programs

and

data.

The

physical

1-2

packaging

of the

user terminal takes

one of

three console configurations.

The

first console combines a video display

and a

TD-24

cassette drive

(2216/17

console)

shown

in

figure

4; the

keyboard

is

packaged separately

(2215,

2222, 2223; figure

4). The

second console combines

the

smaller

9

inch,

(diagonal)

video display, a TD-24

cassette drive,

and an

upper/

lower

case Keyword Keyboard identical

to the

2223 keyboard

Descriptions

Options

1 or 21

(OP-I/

OP-21) provide matrix statements designed

\ to

reduce execution time

and use

less

RAM

than would

be

required using

standard

2200

statements

to

program matrix operations.

Options

2 or 23

(OP-2,

OP-23) allows

the

user

to

custom-tailor

input/output

operations

to

suit special peripheral devices. This option

also facilitates high-speed character code translation

and

data

packing/

unpacking.

Option 3 (OP-3)

allows individual alphanumeric characters

in a

line

of

program text, data values,

or

program

text

currently being

entered

from a Keyboard,

to be

altered, deleted,

or

inserted without

_,

inputting

the

entire program line

again.

Options

l* or 31

(OP-4,

OP31) cause

an

audible signal

to

alert

the

system user when (for example)

an

error occurs under program control.

The

alarm

may be

sounded

by

programming a predesignated

HEX

code wherever

desired.

Option 5 (OP-5)

provides

six

matrix statements

for

flexible

and

rapid

searching, moving,

and

The

Model

2250A

I/O

Interface

Controller

(8-Bit-Parallel)

enables

interfacing

of

8-bit parallel

I/O

devices. Parallel 8-bit data

can be

transmitted

or

received

by a

2250A/2200

system.

The

Model

2252

Input

Interface

Controller

(BCD

10-Digit-

Parallel),

an

input-only interface,

is

directly compatible

to

most

digital meters

for

on-line applications.

It

automatically converts

each

BCD

digit

to an

ASCII equivalent code. Optionally,

it

also

can

be

used

to

receive

up to 40

discrete bits

of

parallel binary data.

The

Model

2252A

is a

later version

of the

2252,

and

allows manual

selection

of 1 to 10

parallel

BCD

digits

to be

input

to the

2200

CPU.

Groups

of 4

discrete binary

bits

each

may be

entered

by the

same select

feature.

Generally speaking, selection

of

less than

10

digits input

allows faster input processing cycles.
