This is the secret to the Mac IIsi interrupt:

    You must have MacsBug 6.2b1 or later (I have 6.2b2) installed in
    your system folder.

Make sure that you restart (if I even need to say that) and anytime you 
press command-power you will immeadiately generate a NMI. There is no 
1 second delay when you have set up your system this way. The trick is
finding yourself a copy of 6.2b1, but they are around.
