Buzzzz..  I noticed my info might not help you.  Your DS5000/120 3MIN
differs from my DS5000/25 MAXINE in how to hold serial ports.   3MIN
does not have "dtop0" for keyboard/mouse pair and "isdn" for sound.
So, I'm not sure what prevents your 3MIN from booting off, now.
Could anyone out there who has 3MIN tell how boot message likes like?

It might be a chance for you to try 1997-3-16 snapshot instead of
1996-9-17 (which was pretty close to release 1.2, I guess)
