**GC101/102     12/16MHz PC/AT Compatible Chip Set             c:Feb88
***Info:
The GC101/GC102  is a fully  IBM PC/AT compatible chip  set supporting
the 80286  CPU at  clock Speeds  up to  16MHz. This  highly integrated
three chip solution features  high performance, low power consumption,
low board space requirements, high  reliability, and low cost. A fully
PC/AT compatible system maybe implemented with this chip set, the CPU,
Keyboard Controllers, RTC and 7  other devices plus memory.  This chip
set supports 256K and 1 Mbit DRAMs in configurations up to 4 megabytes
at zero or one wait state.  Zero wait state operations is supported up
to 12MHz and one wait at up to 16MHz.

The GC101 performs CPU and Peripheral support functions including that
of  DMA  Controllers, a  Memory  Mapper,  Timers, Counters,  Interrupt
Controllers, a  Bus Controller, and their  supporting circuitry.  This
device is packaged in a 160 pin flat pack.

The GC102 maybe configured as  either an Address Buffer or Data Buffer
by strapping one pin high or low.  This chip replaces address buffers,
data  transceivers, memory drivers,  parity generators  and supporting
circuitry. This device is packaged in an 84 pin PLCC

**GC101/102/103 12/16MHz PC/AT Compatible Chip Set + EMS 4.0   c:Jul89
***Notes:...
***Info:
The GC103 is a companion chip  to the GC101/102 AT chip set. Replacing
the GC102  in its Address Buffer  mode, this chip adds  logic to fully
implement LIM, EMS  4.0.  This device expands the  capabilities of the
GC101/102  chip set.   It adds  support for  up to  8MB of  memory and
Shadow RAM for systems  and video BIOS. The register-intensive design,
combined  with the  use of  system memory,  offers extremely  high EMS
throughput compared with EMS  systems using fewer mapping registers or
expansion  memory. The  GC103 contains  a chip  mapping  register that
allows  EMS  to operate  at  full  system  speed without  adding  wait
states. With 2 sets of  32 EMS registers context switching in hardware
as well as software is supported.

The GC103 provides address buffering  for the expansion bus, local I/O
bus, and the  system board DRAM.  Address ,  DMA, and Refresh controls
are  included  in the  GC103.  The  chip  integrates additional  logic
previously implemented discretely in  the GC101/102 board design. This
device is packaged in a 160 pin quad flatpack.
