**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.
