Don't be surprised if the first try doesn't work, as not all 1400
RAM work together.  The only way to be sure is to find a 48.

thanks to victoria and all who offered help, but I am thinking malcom's
suggestion is the way I'm going to have to do it. My original goal was to
buy another chip so that I could max it out at 64, but I didn't know what to
start looking for - a 16 or a 24.
I'll find out soon enough, where's that screw driver? oh there it is... ok
now the hammer...

Nope, there are 16 and 24MB cards for 1400s.

I'd count the number of chips on each card as a starting point.

Actually I wouldn't, I'd rip one out and reboot and see what I'd removed,
it'll only take a minute.

Also David & K and anybody -- apologies for firing off an irrelevant answer
without thinking even once, much less twice.  The six slots are not on a
1400 (I don't even *have* a 1400) or on any kind of PB at all, but on my
7600 (desktop) where resides the System Profiler that I was checking to see
that it does indeed (on that machine anyway) detail the various vbits and
pieces of installed RAM.  All this popped into my head, what little there is
of it, after going offline yesterday.  Also popped the obvious answer to the
original question, which was how to tell the sizes of the two stacked memory
cards without opening the 'Book.  It *has* to be an 8MB and a 32MB, doesn't
it?  Don't they all come in sizes corresponding to powers of two?  If so
that's the only combination that adds up to 40.

Egg on my face,
Victoria

what OS are you using? it has evolved, maybe you'll need 8.1 to do 
that ? System info should be the place to see that ? maybe the PB is 
an exception?

Yep, that's all that shows in mine, too (8 and 52MB).

Re: powerbook 1400 stacked memory sizes?

[David Allen]

You list six slots on a 1400?  What OS are you using?  I also only show the
Logic Board RAM and the Expansion RAM with OS 9.1. (16 and 48 respectively for
the 64 Meg Max.)  The only way I've found to check RAM module sizes is by
removing and checking the numbers, or removing one of the stacked modules and
seeing what difference there is between the original and the new amounts.

My PCI Macs show all of the slots, (8 in my 7600/8600s) but my 1400s show only
the 2 slots. (Profiler adds the soldered on motherboard 8 megs of memory to the
Apple memory card for the "Logicboard" memory and the single slot into which you
can put a single or a pair of stacked 3rd party modules for the "Expansion"
memory.)

Hi Wayne -- I just looked at mine again:  it lists 6 slots by name, and
indicates the size of the module in each (I tried to copy and paste the
list, but system profiler doesn't seem to allow even *that* much meddling.)
Why yours doesn't do the same I have no idea, but surely somebody else on
the list will be able to tell you.

Best,
Victoria

mine shows 56 built-in,
when i click the arrow,
it shows 
16 logic board
40 expansion

but there are two stacked ram modules inside, so the 40 = two modules of
unknown capacity and profiler doesn't show what size the individual modules
are.

thnx

Sure:  just click on the little right-facing arrow in the System Profiler
next to Built-in Memory, and a little list will drop down, detailing the
whole thing.
