Type 1 Questions
Who is in charge here? You are number three. Who is number
one? >laughter<
If you don't get the Iron Maiden tune, then try the
following trivia.
Send answers to ME!
Why are there two 32MHz oscillators? One for bus speed
and cpu clock?
Which one does what?
Why are there two N8259A-2?
From David Beem
Each handles 8 hardware interupt
lines. The first
does IRQ 0 through IRQ 7, the second IRQ 8 through IRQ
15 (which are cascaded
into the IRQ 2 line of the first).
What are those damnable inductor networks for? (LNx)
Where does the floppy controller get it's clock from?
82077 use a 24MHz
osc...

The only RAM this chip has on it is
the 64-bytes
of CMOS memory. The other MCA configuration information
is in the U145
NEC D446G-20L chip (U79 Hitachi HM6264LFP-15T on the
Type 2 planar). Thanks,
David!
