**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.)"
