**Spelling errors/mistyped words
Yes, I  know there are  spelling errors,  and things are  mistyped. It
seems no matter  how hard I try  my fingers hit 't'  twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times.  I  don't have the  time or the will  to check the  spelling of
everything. Basic spell checking has been peformed. Please let me know
if  there is  anything that  would lead  to incorrect  information, or
something  is so  mangled  that  it needs  revising.  But  if you  can
basically  understand  what was  intended,  just  cope with  it.  Just
cope:-)

BTW, "110" port is  an "I/O" port that has been OCRed  badly, as is an
"1/0" port.

**VL82C425         486 Cache controller                              ?
***Info:...
***Versions:...
***Features:
o   Single chip second-level cache controller optimized for use with 
    the VL82C486 System Controller
o   Look-aside architecture allows cache to be board-level option
o   Write-back architecture for increased write performance
o   Direct Map with external TAGs
o   Up to 33Mhz operation
o   Supports single motherboard designs for the following cache sizes:
    - 64 KB  (caches 8 or 16 MB DRAM)
    - 128 KB (caches 16 or 32 MB DRAM)
    - 256 KB (caches 32 or 64 MB DRAM)
    - 512 KB (caches 64 or 128 MB DRAM)
    - 1 MB   (caches 128 or 256 MB DRAM)
o   Low total cache system cost:
    - Uses commodity SRAMs for Cache Tag and Cache Data
    - 25 ns data SRAMs; 20 ns tag SRAMs at 33 MHz
o   High Performance:
    - 2-1-1-1 Burst Mode read cycles with two banks of data SRAM
    - 2-2-2-2 Burst Mode read cycles with now bank of data SRAM
    - One wait state writes on cache-hits
    - Minimum cache-miss penalty
o   Flexibility:
    - Supports 8-bit or 9-bit TAG RAM (inclusive of DIRTY bit)
    - Supports one or two banks of SRAM
o   Maintains full coherency during DMA/Master Mode Cycles
    - The VL82C425 is transparent to software, acting as a front-end 
      to system DRAM
o   Setup/sizing mode provides direct access to cache SRAMs
o   128-lead metric quad flat pack (MQFP)
