THE

VIDEO DISPLAY

The

left-half

of

the

original

SO-column

display

is

copied

to

the

40-column

display.

The

BASIC

prompt

character

")"

and

the

flashing

checker-board

cursor

will

be

displayed

on

the

next

line

as usual.

SO-column

text

SO-column

text

is

especially

suitable

for

word-processing

applications

.

since

the

document

is

displayed

on

the

screen

in

the

same

way

they

will

be

printed

on

paper

so

·

that

you

can

edit

the

format

of

the

print-out

on

the

screen

easily.

To

switch

from

40-

column

mode

to

SO-column mode,

type

the

following

BASIC

statement:

]PR#3<CR>

The

entire

screen

will

be

cleared

leaving

the

BASIC

prompt

")"

and

the

cursor

on

the

top-

most

row

of

the

screen.

Note

that

the

cursor

becomes a

non-flashing

white

block

to

inform

you

that

you

have

activated

the

built-in

SO-column

firmware.

Also,

the

width

of

the

characters

is

reduced

to

one-half

of

that

in

40-column

text

mode.

If

for

some

reasons

SO-column

text

is

undesirable,

e.g. a

low-resolution

TV

is

being

used

as

the

video

display

device,

you

can

inhibit

this

feature

by

throwing

the

"40/

SO

COLUMN"

switch

located

above

the

keyboard

to

the

"40"

position.

If

the

switch

is

thrown

to

the

"SO"

position,

both

40-column

and

SO-column

text

can

be

displayed.
