5-6 Replacing the EPROM in the Little Star CPU
Board
Note: Should replacement of the EPROM ever become necessary, follow the
procedures outlined below:
1. With the power off, remove the Eprom (see below). Use an I.C. removal
tool or a small screwdriver to carefully pry each side up until the chip
becomes loose.
Note: There is a notch or indentation on one side of the chip.
2. Install the new Eprom insuring the notch or indented side lines up (as shown
below). Make sure the chip’s legs do not get bent during installation. If the
chip has fewer pins than the socket, make certain that the “flat” end is flush
with the bottom (no notch) of the socket as shown.
