**CS4021   ISA/486                  (84021/84025)                  c92
***Info: 
The  4021 two-chip  CHIPSet  with CPU  is  designed for  use in  PC/AT
systems.  It  is 100 percent  compatible with 486DX, 486DX2  486SX, or
386DX processors  or Super386 CPUs without any  component changes. The
performance  to cost  ratio is  optimized  for each  CPU option.  This
design allows  the system designer flexibility and  produces an easily
upgradable system.

The 4021 provides  a low cost high-performance  non-cache solution for
486SX systems.  it offers maximum performance benefits through the use
of a CHIPS-patented page interleaving algorithm.

The  4021  CHIPSet  architecture  provides an  alternate,  faster  and
efficient bus interface for speed-sensitive devices like video, disks,
or networks.   This is to overcome  the bus speed bottlenecks  such as
those  associated  with  EISA/ISA  systems  that  can  degrade  system
performance.

Apollo Pro 133Z [VT82C694Z] is an ASUS OEM version of the VT82C694X. It
could be pin compatible with the VT8605 (PM133).
	 
Apollo Pro 133+ Seems to be the same as the 133A.

VT82C694A  is an early internal (to VIA) name for the VT82C694X.
