Greetings,

I recently obtained Carl Sassenrath's Guru's Guide #1 - Interrupts.
In it I noticed a discussion of the IPL Vector Table which starts at
0xFFFFFFF2.  This is where when auto vectoring in the interrupt sequence.
When I read this I went digging through my 68K manuals to see if I
could find where this is talked about.  Couldn't find it.  Scratch head.
Carl clearly knows what he is talking about.  This is weird.  So I
put a logic analyzer on my box and sure enough there it was.

Now my question is this:  Where is this behaviour of the 68K chips
documented?  Also is a similar thing done on 68K20 and the other
beasties?

Whoops a couple of questions.

If you think this is of general interest than reply here otherwise just
send me mail.

thanks,

-c
