Figure 7.7.3-2
To replace each EPROM:
1. Insert the EPROM A into the left-hand seat,
and EPROM B into the right-hand seat.
2. Insert the EPROM pins in the seats, starting
from the bottom, so that the holes in the top
seat remain free.
3. Make sure the reference notch b on the
EPROM is aligned with the reference notch c
on its seat.
4. Make sure the feet of the EPROM are
positioned above the holes in the seat.
5. Push the feet into the seat.
Each EPROM may be irreparably
damaged if its reference notch is not
aligned with the one on the seat, or if its
pins are bent.
