Digital

Drum

Plotter

provides

point,

and

alphanumeric

plotting

capacity

to

any ?>bdel 2200 System

that

has

plot

capability

.

'nle drum

plotter

is

conL,olled

by an 8080

microprocessor,

which

includes

a 512

byte

RAM

memory

that

is

used

to

buffer

plot

information

sent

from

the

Model 2200

CPU.

Vectors

take

5

bytes;

alphanumeric

characters

and

plot

control

characters

are

stored

as

is.

The

manual

control

panel

on

the

Digital

Drum

Plotter

provides

a

number

of

convenient

control

functions

which

include:

manual

slewing

of

the

pen

and

paper,

four

quadrant

axis

rotation

selection,

conveniently

setable

HOME

position

(X

=

O,

Y = 0

origin)

and pen and

paper

movement

limits

to

any

position

on

the

plotting

surface,

plot

interrupt

and

automatic

return

facility,

and pen up

override

•

Plotting

is

controlled

with

the

2200

BASIC

language

PLOT

statement.

The

plotter

has

an

input

buffer

which

allows

a number

of

plot

vectors

and

alphan\DD.eric

plotting

data

to

be

stored

prior

to

plotting,

thus

providing

overlap

between

plotting

and

CPU

processing.

The

Model 2272

Plotter

has

built-in

alphanumeric

character

generation

capability

which

plots

a

standard

64

character

ASCII

set

in

15

selectable

character

sizes.

A

zero

reference

parameter

{HOME)

permits

quick

resetting

of

the

pen and

paper

position

to

any

manually

set

origin,

either

under

nanual

or

program

control.

Additional

plot

codes

are

available

to

allow

efficient

plotting

of

prestored

plot

information,

special·

lettering

and symbols

via

binary

plot

vectors

and

to

perform

plot

initialization

functions

under

program

control.

Manual

controls

permit

setting

the

home

position

coordinate

axis

to

one

of

four

orientations

acconunodating

plots

of

many

shapes.

Manual

controls

also

permH

slewing

the

pen

position

as

desired,

placing

the

pen

in

the

'up'

position

and

clearing

the

plotter

buffer.

Both

English

and

metric

versions

plot

with

interchangeable

pens;

the Model

2271-1

(-lM)

has

a

single

pen

assembly

anri

the

Model

2272-2

(-2M)

has

an

optional

three

pen

r.arria~L'

assembly.

The

16

inch (40. 6

cm)

plotting

axis

is

covered

by

a

cable

driven

pen

assembly;

the 160

inch (406

cm)

axis

is

operated

by

the

pinfeed

paper

mechanism.

The

English

version

drum

plotter

supports

approximately

3200 i,,,..remPnts

of pen movement

in

the

left-right

direction

(16

inches

x

200

steps/

inch) and 16383

increments

of

paper

movement

in

both

the

forward and

reverse

direction

if

HOME

position

is

not

reset;

there

is

no

restriction

on

paper

movement

if

HOME

position

is

reset.

The

metric

plotter

has

approximately

4064

increments

in

the

left-right

direction

and 16383

increments

of

paper

in

the

forward-reverse

direction

if

HOME

position

is

not

reset.

The

standard

plotter

(metric

or

English)

is

100%

compatible

with

the

2212

protocol

except

that

64

ASCII

plotting

characters

are

supported

instead

of

48.

Options

will

include

a

three

pen

carriage

assembly,

additional

microcode

(PROM)

chips

to

support

expanded

built-in

plotting

functions

and an

automatic

paper

roll

feed

handler

which

will

100unt

on

the

rear

of

the

plotter.

The

plotter

connector

is

designed

to

connect

to

the

2221W

1/0

controller

board

in

the

2200

chassis.

The

plotter

drum

supports
