**82C599    PCI-VLB Bridge [no datasheet, some info]                 ?

"The Contaq Chipset (Contaq: 1080/4224) (8/27/95)

The Contaq 82C599  is paired with one of  their 486VL chipsets (82C596
or  82C597) and  bridges directly  from the  486 CPU  to the  PCI bus.
Paraphrased from the Contaq spec.:

The  82C596 system  controller provides  the CPU  interface,  VESA bus
interface, ISA bus controller, etc. The 82C599 PCI controller provides
the bridge  between PCI master/slave  agent and the  ISA/VESA standard
expansion  bus; it arbitrates  all the  bus transactions  between host
CPU, PCI agent, VESA device, and ISA device.

(Which sounds to me like the PCI bus is attached to the VL bus, rather
than to the CPU, which will cause PCI performance degradation.)"

***Notes:...
***Info:
The  82C801  SCWB2  can  be  summarized in  four  words:  integration,
performance,  features  and  reliability.   The  best  value  for  the
OEM/system house.

The SCWB2 is  the result of an engineering team driven  by the need to
provide  the fastest, most  reliable solutions  in the  smallest, most
cost effective package and having complete confidence in compatibility
and reliability of the product. With a feature set that doesn't take a
back seat to any solution in the market.

From the 50  MHz Write back Cache to complete  local bus support, this
chip is  everything a  system designer needs  to provide  his customer
with state-of-the-art solutions for high performance PCs in the market
today - and for some time to come.

The  SCWB2 is designed  for the  OEM/system house  who needs  a single
chip, local  bus, lightning performance, design  flexibility, 8 banks,
quick-to-market, and cost effectiveness.
