I don't know if you've tried this already, but have you checked the
ID bytes? Apple cards are supposed to (!) have a certain signature
byte which tells you what the cards' function is.
do this:
]CALL-151
*C40C
it should dump C04C- xy where x is a hex code of one of the following:
$0 - "reserved"
$1 - printer
$2 - joystic [how many joysticks for the // had cards?]
$3 - serial or parallel i/o card
$4 - modem
$5 - sound or speech device
$6 - clock
$7 - mass storage device [hehe, back when 5mbs was "mass storage"]
$8 - 80 col card
$9 - network or bus interface
$A - special purpose (none of the above)
$B-F - reserved for future expansion
y is a "unique identifier for the card, assigned by Apple Technical Support."
when i do this on my //e, I get the followgin:
C10C- 31 slot #1, serial card
C20C- 41 slot #2, novation applecat modem
C30C- 88 slot #3, 80 col text card
C40C- 0F slot #4, zoom/modem //e [but it says "reserved" .. go figure.]
C50C- A0 slot #5, empty
C60C- F0 slot #6, disk controller [wtf isn't this in there, eh?]
C70C- 00 slot #7, empty
this came from the super serial card manual, page 51, (c) 1981, so it might
be a bit dated, but it might be of some help.. although i have no clue
as to why the zoom or the disk controller card isn't showing up in here.
there's another [better] way to tell what's in your slots; i think it
was published in nibble years back as a 1 or 2 liner. maybe some kind
soul will remember and post it up.

PS- I have both a mac and an apple //, wanna make something of it? I wouldn't
give up either. The mac does loads that my // can't do, and the //
does stuff that my mac can't do. Power is defined by what you can get
a computer to do, not by the manufacturer or model.
