**VL82C286-SET     TOPCAT 286/386SX PC/AT-Compatible Chip Set        ?
***Info:...
***Configurations:...
***Features:
o   Two-chip, PC/AT-compatible chip set capable of use in 80286-based
    systems up to 20 MHz or in 80386SX-based systems up to 25 MHz
o   Two 160-lead plastic quad flatpacks, 1.0 and 1.5 micron CMOS
o   Memory control of one to four banks of 16-bit DRAM using 256K, 1M,
    or 4M components allowing 32M bytes on system board 
o   Two-/four-way page mode interleaving or direct access on system 
    board memory
o   Programmable DRAM timing parameters
o   Remap option allows logical reordering of system board DRAM banks
o   Staggered system board refresh optionally decoupled from slot bus 
    refresh
o   Built-in "sleep" mode features, including use of slow refresh 
    DRAMs in power critical operations
o   Hardware supports full LIM EMS 4.0 spec over entire 32M bye memory 
    map
o   DMA expanded to allow transfers over 32M byte range
o   Shadow RAM support in 16K increments.
o   Support for 80287 or 80387SX numerical coprocessors
o   Internal switching and programmable CPU clock support for PC/AT-
    compatible and "turbo" modes
o   Asynchronous or synchronous slot bus with "Bus Quiet" mode
o   Build-in real-time clock and scratchpad RAM
o   Additional 64 bytes of battery backed RAM in RTC
o   Supports 8- or 16-bit wide BIOS ROMs
o   In-circuit test modes
o   Support for the VL82C335 Cache Controller is provided by the 
    VL82C320A
