**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.
