**82C596/A 3/486 Writeback Cache [no datasheet] <11/11/92
Possibly two variant, or one version with two names, one being a
shorthand:
82C596
82C596A
ftp://ami.com/archive/Other_Manuals/!index.txt
lists the A variant with the date 11/11/92. No date for non-A:

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

"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.)"
