3.1.3Step 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 Figure 2-2. Location of the EPROM socket 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
