**TACT84500   AT Chip Set (486, EISA) [no datasheet, some info]    c91
***Notes:
InfoWorld Oct 28, 1991 p38:
"...Unlike earlier EISA chip sets, Ti's Tact84500 is comprised of only
four VLSI chips for controlling the bus, memory, peripherals, and data
path unit. The Tact unit can also control eight EISA bus masters along
with DRAM and a single-layer  EISA-bus write buffer.  According to TI,
the suggested  price of the  EISA chip set,  at $130 in  quantities of
100, should  make EISA-based  systems price competitive  with existing
ISA-based systems."

At least one of the chips is called 84542. This is probably the memory
controller.

**VL82C031/032/033      PS/2 Model 30-compatible chip set          c88
***Notes:...
***Info:...
***Configurations:...
***Features:
VL82C031:
o   Supports 8088 or V30 CPU at 8 MHz or 10 MHz zero wait state 
    using 150 ns DRAMs
o   Generates programmable fast and normal timing for PC memory
o   Provides either DRAM or SRAM control
o   Supports up to 8M bytes of expanded memory
o   Supports 256K or 1M bit DRAMs on EMS memory
o   Arbitrates the system bus among the CPU, DMA, math coprocessor,
    and DRAM memory refresh cycles
o   Provides four channels of 8 MHz DMA as well as burst mode
o   RAM pin available to select static or dynamic memory interface
o   Power down mode for low power standby operation

VL82C032:
o   Controls Model 30-compatible system keyboard and mouse
o   Integrates the following functions on a single device:
    - 8253-compatible timer/counter
    - Dual 8250-compatible serial communications controller
    - Bidirectional parallel port controller
    - 8259-compatible interrupt controller
    - 58167-compatible real-time clock
o   Decodes subsystems for floppy disk, hard disk, and video
o   Provides chip select logic for serial/parallel ports, disk 
    controllers, and real time clock. 

VL82C033: (from the '88 version):
o   Provides a uPD765A-compatible floppy disk controller
o   contains a precision analog data separator
o   Integrates an internal phase comparator, and voltage controlled 
    oscillator (VCO)
o   Provides the system with three data rates:
    -250K bit-per-second
    -300K bit-per-second
    -500K bit-per-second
