(Another) Possible Error in Pinouts

I think there may be another error in the pinouts on
our data sheets.

For the Flex Expansion busses (all three of them) hole
number 8 is supposed to correspond to Dedicated Input 1
(DI1) and pin number 99.
This is a stark contradiction!!!

On the Flex10K device data sheets, the pins that are
listed as being dedicated inputs for 240 pin devices
are pins 90, 92, 210 and 212. Hmmm...no 99!

Also pin 99 is supposed to be available on FLEX_EXPAN_A
at hole number 54. (So why would they put it elsewhere
as well).

I haven't been able to check on the actual board
(somebody locked the door to GB150!) whether hole
number 8 is connected to pin 99 or pin 90, but I'll
betcha' dollars to doughnuts that pin 99 IS NOT DI1.
(I'll also bet that hole number 8 is connected to
pin 90, the real DI1).

Anyways, I've attached the Altera website link if you
want to see for yourself (p.124 of the data book or
p. 104 of the PDF file).


Jayesh (ahh...details).

P.S. Hole number 32 on FLEX_EXPAN_C connects to pin 199
NOT 198 (I don't know if this correction was listed on
the handout we received). Although this doesn't really
matter to us since you (probably) aren't using expansion
bus C.
