Since the Mac Mini Group appears dead, I guess I'll post here...

I bought a G4 Mini about six months ago to use as a compact iTunes
server for the house, replacing the big hulking Beige G3 tower I've
been using.

I'm finally configuring the thing and have a few questions.

1)   Does anyone know what the Wifi slot is?  From the Apple Hardware
Developer Note, it looks like it's probably a combination PCI slot and
USB connection (Wires for both on one connector).  If one has the
riser card does that provide a standard Mini-PCI connection, or is it
still proprietary?  I'm half-heartedly looking for a way to get SCSI
on the thing, so it can also run my household backup system as well.

If I do anything with this SCSI idea I'll need an Airport card or
combo Airport/Bluetooth card from which to reverse engineer the
connections.   Anyone have a dead one they'd like to dispose of?
Failing that, is there an inexpensive source of these cards or have
they become expensive?

2)  I opened it up last night.  I thought that tiny hole on the lower
right was a port for a manual eject pin to the optical drive, but it
looks like there's an IR receiver behind it.   Does the G4 Mini have
an IR receiver?  I researched this a while back and thought that only
later Minis could use an IR remote.

3)  The Mini I bought has a CD-RW/DVD-ROM and I want to install a DVD-
RW drive.   I have a Toshiba TS-632 and a Hitachi AGW-4080 on hand.
Any opinions on which is the better choice?

4)  Everything I've read says the maximum RAM is 1 GB.   Anyone ever
successfully install more RAM?

The Apple Developer Note (which also claims 1 GB maximum) states:
"Signals A[0] - A[12] and BA[0] - BA[1] on each RAM DIMM make up a 15
bit multiplexed address bus that can support several different types
of SDRAM devices."

Now, that statement isn't super-accurate, because while the address is
multiplexed the Bank address is not.    So the maximum addressing
possible is 13 address bits twice (twice is what the multiplexing
means) for 26 address bits or 64M addresses, and the two Bank bits
yield up to four banks.

So, if one builds a DIMM out of sixteen 64M X 4bit X 4bank  parts, one
would have get a 2 GB DIMM.  Hmmm, checking some memory datasheets, it
looks like there may never have been 64M X n X 4 bank parts.  They all
seem to go to 8 banks before they go to 64M addresses.

Thank you for any helpful or humorous answers.
