The Peak 555A series only support the high speed pipeline burst SRAM.
The default L2 Cache is 512 KB.
3.3 Change CPU
The Peak 555A uses the 321 pin PGA socket rather than the ZIF socket,
so it needs force to push or pull the CPU into or out from the socket.
Normally, you have to use some tools to pull the CPU out from the
socket. To put on a new CPU, please place the new CPU on the
middle of the socket, orienting its beveled corner to line up with the
socket’s beveled corner. Make sure the pins of the CPU fit evenly to
the socket openings, then press the CPU until all the pins fit into the
socket. Be sure to re-arrange the DIP switch setting for the correct
clock and Core/Bus ratio. The Peak 555A supports many kinds of
CPU’s, please refer to the DIP switch setting table for the right
arrangement.
