Allow me to redeem myself in the eyes of pickle. :) Ahem. The parts in your IIfx are
as follows.
The riser card is an adapter board that converts your PDS slot to a NuBUS slot. That's
probably where your NuBUS SuperMac card is attached. Those adapters SOMETIMES come
with FPUs onboard. The 30-pin RAM is correct, but what LOOKS like a 72-pin SIMM slot
is really a ROM SIMM slot for upgrading your Mac's ROM to a different version, though
I have seen no real advantage to doing this as of yet. It's not for cache, as I asked
before. [I knew it wasn't, but it's worth asking]. You add cache using the PDS/NuBUS
slots. Your other slot MIGHT be a NuBUS slot. I forgot what machine you've got so I
can't really tell you, though. I'll say it's NuBUS though, since as far as I know, no
Mac has 2 PDS slots. :)
Hope this helps,

Thanks, so far...
And peeking inside my Quadra, I see what was meant by
the connector being longer. Learn something new every
day... Now I'm trying to find out just which SuperMac
card I have on here. I'll be replacing the PRAM
battery shortly, hopefully that'll help.
What would also help (if I could find one) would be a
layout and description of what's in this (and other
macs.) I see the 30-pin memory, what looks like a
72-pin (which I was actually assuming was the PDS,
when I thought the PDS was a Nubus... oy... at least
that makes sense now!) that I'm assuming is for
cache?? and on the riser, what looks like either an
upgrade or FPU socket. From what I've seen so far of
the Apple manuals, they're all text (no, I don't have
the originals, just what I can find online.)
At least I have the stuff on back figured out. <g>
Thanks again,
Eric
