CACHE
Q15.
Can the Endeavor 486C computers include secondary cache?
A.
Yes. The system board is capable of supporting up to 256KB of external
SRAM cache memory.
There are ten CACHE sockets on the main system board. These sockets
accept 8KB or 32KB SRAM chips installed in the sockets of BANK0 and
BANK1. BANK0 must be filled before BANK1.
The SRAM type used for sockets U15 and U16 must match the type
installed in the banks.
