Yes, you're right.  In my post I mistakenly conflated the Plus' logic board with that of the SE; mea culpa.  The PRAM battery for the SE and SE/30 are both located on the logic board.

Does this photo help:


(Damian Ward's photostream, not mine)

...it shows the location of the PRAM battery on the SE/30's logic board; the SE and SE/30 logic boards have the same form factor, so the picture should work for both.  Please shoot me a mail and let me know when you locate the PRAM battery.

The logic board form factor for the Classic is the same for the Classic II as well.  Can you please take a look at this teardown:


...and tell me if if works for you?  The PRAM battery is a standout red and is featured in pictures #12, #15, and #20 under the "Macintosh Classic II disassembly" header near the top of the page (scroll down a bit).

I'm afraid they're not very good pictures, and I'll see if I can find some better ones as time permits, but take a look at those in the meantime; they might be enough.

The Color Classic has a different logic board form factor than any of the other machines.  I will have to take a look around and see if I can find a good picture of the CC logic board (anyone?).
