**??????     "Cougar/Bobcat" 386DX/486DX chipset [no datasheet] cNov91
***Notes:
"ETEQ  Microsystems Inc,  headquartered in  Milpitas,  California, has
developed the  Cougar II  and Bengal chip  sets to support  Intel Corp
iAPX-86 clock  speeds above 50MHz: a hardware  turbo switching feature
has been incorporated into the  Cougar and Bengal 80386 and 80486 chip
sets, and  this enables  users to mix  the type  and the order  of the
DRAMs  in the  system;  also,  they support  a  Weitek Corp  3167/4167
co-processor   without   any   external  programmable   array   logic;
engineering samples of the 50MHz  chip sets are shipping from ETEQ and
production volumes  will begin in the  first quarter of  next year; no
prices. " - 21st November 1991

Since the Bobcat uses some of the same parts it is assumed to be just
a different variation.
