**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.

**VL82C108 TOPCAT Combination I/O chip                               ?
***Info:
The VL82C108 Combo  chip replaces with a single  100-pin chip, several
of   the   commonly  used   peripherals   found  in   PC/AT-compatible
computers. This  chip, when used with VLSI  PC/AT-compatible chip set,
allows designers to implement a very cost-effective minimum chip count
motherboard containing functions that are common to virtually all PCs.

The on-chip UART  is completely software compatible  with the VL16C450
ACE.

The bidirectional  parallel port  provides a PS/2  software compatible
interface between  a Centronics-type printer and  the VL82C108. Direct
drive is provided so that all  that is needed to interface to the line
printer is  a resistor/  capacitor network. the  bidirectional feature
(option) is software programmable for backwards PC/AT-compatibility.

The  keyboard/mouse  controller  is  selectable  as  PC/AT-  or  PS/2-
compatible.

Included  is  the control  logic  necessary  for  the support  of  the
Integrated Drive Electronics (IDE) hard  disk bus interface. Hard disk
drives which support the IDE interface often refer to the interface as
"AT Bus" compatible or "Embedded AT Bus" compatible.

The  Combo I/O  chip also  includes  selectable chip  selects for  the
internal  UART and  printer port,  and  four fixed  chip selected  for
external floppy and hard disk controllers.
