3.1.3 Step 3: Replace the

PSOS EPROM

Locate the EPROM/SRAM socket

(Figure 2-2) on the microcontroller

card and note that the Pin 1 locator

notch on its case is towards the outer

edge of the board—you’ll want to

similarly position the new PSOS

EPROM.

Pry or pull out the socketed

EPROM chip. We’d prefer that you

use a special “chip-puller” tool, but

if one isn’t handy, use a thin, flat-

bladed screwdriver and gently pry

up each end of the chip until it lifts

out of the socket freely.

EPROM chips are sensitive to static electricity. Be careful to handle

them by their case and store them on conductive foam. Don’t touch

the pins with your fingers, and be particularly careful not to bend

any of their 28 delicate connector pins.

Now carefully remove the new PSOS EPROM that came with the Gripper/

Experimenter’s Module from its protective foam and insert it into the EPROM socket. Be

sure to line up the Pin 1 notch and insert the pins in their respective socket holes. Then
