Installing the new EPROM
If an EPROM is included in the upgrade package, you must use it to replace the EPROM that is
installed in Socket A of the evaluation board. This upgraded EPROM has the same pinout as the
original, however, it contains new RISM (Reduced Instruction Set Monitor) code. No jumper
changes are required.
NOTE
Socket A can accept either a 32K, 64K, or 128K EPROM. Because of this,
when you install the 32K EPROM provided by Intel there will be four holes
left open by the notch. See
Figure 3
for the correct orientation of the EPROM.
