**Spelling errors/mistyped words
Yes, I  know there are  spelling errors,  and things are  mistyped. It
seems no matter  how hard I try  my fingers hit 't'  twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times.  I  don't have the  time or the will  to check the  spelling of
everything. Basic spell checking has been peformed. Please let me know
if  there is  anything that  would lead  to incorrect  information, or
something  is so  mangled  that  it needs  revising.  But  if you  can
basically  understand  what was  intended,  just  cope with  it.  Just
cope:-)

BTW, "110" port is  an "I/O" port that has been OCRed  badly, as is an
"1/0" port.

***Notes:...
***Info:
The new  Texas Instruments single  chip TACT82411 contains  the system
logic and most of the peripheral functions needed to build a 12-20 MHz
80286-based computer that is 100%  compatible with the IBM PC-AT. Only
seven logic components plus  memory, CPU, and coprocessor are required
to  complete an  80286 system  board.  The chip  also supports  system
boards which use the 80386SX.   The TACT82411 is packaged in a 208-pin
quad flat pack (QFP).

Because  the TACT82411 is  manufactured with  TI's 1-micron  EPIC CMOS
technology,  it provides a  high level  of integration  and high-speed
state-of-the-art performance at relatively low power consumption. This
combination  permits  systems  that  are smaller,  lighter,  and  more
sophisticated,  but with  lower power  consumption -  an  ideal comab-
ination  for portable,  battery-powered  systems such  as laptop  com-
puters.  Another benefit  of high-integration is increased reliability
due to fewer board connections.   In addition, product cost is reduced
because new system design and testing are simplified.

Redesign  of existing multi-chip  or discrete  80286 system  boards is
easy and  cost-effective because  of the straightforward  and flexible
structure of  the TACT82411 chip. System boards  which were originally
designed to operate at 12/16 MHz  can be easily upgraded to operate at
20 MHz. Non-PC  applications using the 80286, such  as instrument con-
trol, automobiles,  and medical equipment,  can also benefit  by using
the TACT82411 chip. Architectural variations can be easily implemented
for  special-purpose systems such  as LAN-based  diskless workstations
and PC-based portable test equipment.
