Procedure

4.1. I

Make

sure

the

programming

sockets

are

empty,

SWI

is

off

(switch

lever

to

the

right

side),

and

the

LED

is

off.

If

the

LED

is

on,

perform

a

read

command

with

your

monitor

for

a

location

in

the

programming

socket

address

block.

4.1.2

Make

sure

the

data

you wish

to

program

is

in memory.

4.1.3

Insert

the

EPROM

in

the

appropriate

socket

-

U22

for

2708,

U23

for

2716.

Verify

it

is

erased.

(Section

~.~)

4.1.4

Enter

the

program

of

Section

4.2

or

4.3

at

location

l~eH.

Modify

the

starting

address

of

the

memory

to

be

copied

to

match where

your

data

is

located

(Section

3.2).

4.1.5

Turn

SWl

to

the

ON

position.

4.1.6

You

are

now

ready

to

program

the

EPROM.

Execute

the

routine

at

location

lee.

4.1.7

During progr.amming

the

LED

should

be

lit.

Programming

time

for

the

2708

should

be

about

160

seconds,

for

the

2716, 100

seconds.

After

programming

is

complete

the

LED

wilt

turn

off

and

control

will

be

returned

to

your

monitor.

4.1.B

Turn

off

SW1.

4.1.9

Verify

the

data

was programmed

correctly

by

comparing

data

in

memory

to

data

in

EPROM.
