Appendix B – External Cache (COAST)
Installation
All CPU configurations–except the 75 MHz and 100 MHz models–provide 512 Kbytes
of cache-on-a-stick site (COAST). This external cache is supplied on a printed circuit
board similar to the DRAM modules. This printed circuit board is designed to plug into
the socket at U39, which is next to the two DRAM sockets.
To install the cache, line up the COAST module with the socket and apply light, steady
pressure until the COAST module is seated. The socket is keyed so that the module can
only be plugged in one way.
