**A note on VESA support of 486 chipsets.
Many chipsets state  that they support VESA local  bus.  In some cases
these actually  implement VLB somewhat  like PCI, where it  is entirly
decoupled from the CPU bus. Chipsets  that do not state they work with
VLB,  may  be found  on  motherboards  that  contain VLB  slots.   VLB
is  *basically*  The 486  CPU  pinout in  a  slot  form. Unless  these
m/boards contain  some additional  chips, there VLB  implementation is
directly coupled to the CPU.

***Info:
The VL82C113/VL82C113A SCAMP Combination I/O chip, when used with VLSI
SCAMP  chips,  allows designers  to  implement  a very  cost-effective
minimum  chip  count  motherboard.   This  chip  combines  a  keyboard
controller and  a real-time  clock with the  address registers/buffers
and buffers  which are normally required  in PC/AT-compatible systems.
The VL82C113/VL82C113A  features an AT-compatible  keyboard controller
with integrated PS/2 mouse  support and a 146818A-compatible real-time
clock.  In addition, the VL82C113/VL82C113A has 64 additional bytes of
battery-backed CMOS RAM for use in extended system setup.
