Upgrading from 8 MB to 16 MB
If you are upgrading a FRE-2 processor module from 8 MB to 16 MB, your
upgrade kit contains two identical 72-pin SIMMs.
To upgrade the FRE-2 processor module to 16 MB:
1. Using Figure 7 as a reference, locate SIMM sockets SI 1 and SI 2 on your
FRE-2 processor module.
Sockets SI 1 and SI 2 should be empty.
2. Holding one of the new SIMMs by its edges, turn it so the keyed (notched)
side faces the center of socket SI 1 (Figure 8).
3. Insert the SIMM into the socket at an angle of about 30 degrees from the
vertical.
