**VL82C031/032/033      PS/2 Model 30-compatible chip set          c88
***Notes:

There seems to be 2 versions of this chipset.
The earlier one from 1988 is described as a three-chip set consisting
of:
VL82C031/OTi-031 System controller
VL82C032/OTi-032 I/O Controller
VL82C033/OTi-033 Floppy disk Controller and Data Separator  
(OTi part numbers are the equivalent from Oak Technologies Inc.)

The later one from 1989 is described as a two-chip set consisting of:
VL82C031 System controller
VL82C032 I/O Controller
(Oak Technologies Inc. is no longer mentioned)

The text  below is  taken from  the 1989  description of  the chipset,
except where stated. It has been difficult to determine to what extent
they  differ.  However  the  'power-down mode'  functionality  of  the
VL82C031 is only mentioned in the later '89 description.
