**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.

**TACT83000   AT 'Tiger' Chip Set (386)                            c89
***Info:
The Texas Instruments TACT83000 AT Chip Set is designed for cached and
noncached 386-based  PC-AT compatible systems running at  speeds up to
33 MHz.  Manufactured with high-speed  1-um CMOS EPIC  technology, the
chip set is functionally partitioned into three devices: the TACT83443
AT Bus Interface Unit (ATU),  the TACT83442 Memory Control Unit (MCU),
and the  TACT83441 Data  Path Unit  (DPU).  The ATU  is packaged  in a
208-lead  plastic quad  flatpack  (QFP),  while the  MCU  and DPU  are
packaged in 100-lead plastic QFPs

These three chips, along with four other logic chips, comprise all the
logic  necessary for  a  fully compatible  16-bit 3868X-based  system.
Since one DPU provides a 16-bit data path, a 32-bit 386DX-based system
requires an additional DPU.

With software-controlled configuration registers  on board the ATU and
MCU,  the  chip set  supports  a wide  variety  of  PC system  config-
urations.  For complete programming  details, see the TACT8300 AT Chip
Set User’s Guide, literature number SRZU001.
