1. What's the secret connector in the middle of 030 NeXT's mother board at
   the front (next to NeXTbus connector)? Somekind of test pins?

2. What exactly happens, when power key is pressed on keyboard?
   Motherboard receives the signal through monitor connector 
   (MON POWER PIN) and on the motherboard battery wakes power supplier
   up using PUP (power up) signal. That's clear this far, but will
   PUP remain active high until power is pressed again on the keyboard AND 
   NeXT's operating system is happy about closing system? Or will 
   PUP drop after PON (power on) is active high? I couldn't find
   precis explanation about this from any of the NeXT's hardware
   manuals. 

3. Can I use 4 MB simms in 030 board?

4. Does NeXT's 2.88 meg floppy drive and 256 meg optical drive use
   same data cable? Is it possible to connect PC's 1.44 meg floppy
   to a NeXT by using the internal optical drive connector? Is there
   schematics available for that connector? (Pins etc.)

Thanks in advance (reply by using email, please).
