**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.

**M1521/23       Aladdin III       50-66MHz                     <Nov96
***Info:...
***Configurations:
M1521 System Controller
M1523 PCI-to-ISA Bridge

M1521 + M1523

There  is  an updated  version  of the  M1523  called  the M1523B.  It
supports Distributed DMA, Serialized IRQ and USB.

The datasheet for the M1543C states that it can be used with the M1521
