**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.

**ACC5500    Multifunction I/O Control Chip for PS2 Model 50/60    c88
***Info:
The  ACC 5500  is a  multifunction chip  designed for  motherboards or
add-in cards  compatible with  IBM PS/2 Model  50/60 systems.  The ACC
5500 has an NS 16450 compatible asynchronous communications element to
build a serial  port and a bidirectional parallel  port interface that
supports a  Centronics type  printer and allows  the parallel  port to
receive  data from  external devices.  The ACC  5500 uses  an external
signal input as the input clock source.
