The 3B2 line uses a 720K floppy drive, You must use 96tpi double or high
density diskettes with this drive, and you are better off if you use the 
high density media ( more reliability ).

Yes, it will improve response time, but you probably will have to re-tune the
kernel to get better response.

The upgrade is installed by adding a second one meg memory card, or by removing
the current 1 Meg card and adding a 2 Meg card.  Using AT&T equipment, max
memory on a 3B2/300 is 4 Megs.

You cant plug in chips, so the question is invalid.

Hope this helps,
