**82495XP/490XP Cache Controller / Cache RAM (for i860)       06/05/91
***Notes:...
***Info:
The Intel 82495XP cache controller and 82490XP cache RAM, when coupled
with a user-implemented memory  bus controller, provide a second-level
cache  subsystem  that eliminates  the  memory  latency and  bandwidth
bottleneck for  a wide  range of multiprocessor  systems based  on the
i860 XP  microprocessor. The CPU  interface is optimized to  serve the
i860  XP microprocessor  with zero  wait  states at  up to  50 MHz.  A
secondary cache  built from the  82495XP and 82490XP isolates  the CPU
from  the memory subsystem;  the memory  can run  slower and  follow a
different protocol than the i860 XP microprocessor.

**VL82C113 SCAMP  Combination I/O chip                               ?
***Info:
The VL82C113/VL82C113A SCAMP Combination I/O chip, when used with VLSI
SCAMP  chips,  allows designers  to  implement  a very  cost-effective
minimum  chip  count  motherboard.   This  chip  combines  a  keyboard
controller and  a real-time  clock with the  address registers/buffers
and buffers  which are normally required  in PC/AT-compatible systems.
The VL82C113/VL82C113A  features an AT-compatible  keyboard controller
with integrated PS/2 mouse  support and a 146818A-compatible real-time
clock.  In addition, the VL82C113/VL82C113A has 64 additional bytes of
battery-backed CMOS RAM for use in extended system setup.
