**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.
