**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.

**VL82C380         Single chip 386DX PC/AT Controller +on-chip cache ?
***Info:...
***Configuration:...
***Features:
o   Highly integrated system solution using VL82C380 single-chip 
    ISA controller, VL82C113A Combination I/O chip and 3 TTLs
o   Supports one- or two-bank write-back cache
    - External TAGs
    - 32 Kbyte to 1 Mbyte cache size
    - 0 or 1 wait state writes
    - Separate dirty RAM not required; first write to clean, valid 
      line sets dirty bit 
o   Caches main system DRAM only
o   Maintains full coherency during DMA/MASTER mode cycles
o   Optional remap of video and hard disk ROM BIOS onto motherboard, 
    allowing use of single BIOS ROM
o   Optional bus acceleration for video accesses, with programmable 
    address regions
o   Software-configurable
o   Utilizes proven 8254, 8237, 8259 megacalls used in all previous
    VLSI Technology PC/AT chipsets
o   High-performance memory controller:
    - One wait state red up to 33 MHz, Zero wait state reads up to 
      40 MHz
    - Automatic configuring of Bank start address
    - Each bank individually configurable for any supported DRAM type
    - shadow RAM support form 640K to 1M in 16K segments
    - Staggered refresh reduces power supply peak currents
    - Decoupled-mode refresh improves performance
    - Programmable refresh frequency for support of slow-refresh DRAMs
    - Up to 64 Mbytes of motherboard memory in one to four banks using
      256K, 1M, and/or 4Mbit DRAM, all motherboard memory is cacheable
    - Direct-drive up to 2 banks (32 Mbyte) of motherboard memory
    - Two-way page mode interleave
    - Supports 32-bit ini-interleaved or interleaved configurations
    - Programmable RAS/CAS timing supported for Cycle-start, Trp, 
      Trcd, and Tacs
