This is a university town and,
so G3's aren't hard to come by cheap if the urge should ever hit me
again.
Beige G3's are OK, and still have SCSI and serial ports. I have a gaggle
of G3 powerbooks that I use at CHM for various recovery projects. Blue
and White machines switched to USB and dumped SCSI and serial, which
make them less interesting. If you want that sort of machine, get 2nd
generation or later Grey G4. Avoid the last couple of generations of
G4's, they had cooling problems...
Putting a 1+GHz CPU upgrade into the earlier G4s makes a pretty decent
system. I'm using one as my main machine at CHM.
I'd probably have to BUY an AAUI-to-RJ45 ethernet
adapter
Probably not worth messing with. You aren't going to be happy with the
performance of a first generation PowerMac.
If you really want a shell in the OS 9 environment, there's MPW.
I remember someone playing with getting a bare-metal OS going on PPC
Macs at one point with a CLI. Don't know how far they got.
This is sort of interesting if you wanted to do some low level turn the
interrupts off kind of programming on the machine, since you can't
actually turn interrupts off completely in the OS 9 environment.

Mine came with a PCI SCSI card, so the lack of onboard SCSI isn't a
problem, but I do miss _real_ serial ports. I play with things like
LCD controllers (yes, there _are_ USB-attached textual and graphical
LCDs, but they aren't as easy to talk to), so it's nice to have either
a real serial port or a real parallel port for simplicity.

The local recycler is selling complete beige G3's for $25 the each:

I'd have to figure out what to do with one, however.

Holy God! An HP 8100 for $100?!
What the hell am I still doing in Brazil??? :oP Buaaaaaaaaaaa

Right. So since Chuck has never had a compact Mac to
play with, who's going to donate him one? I vote it
has to be pre-ADB, to get the full look and feel experience.

There may have been other peripherals than keyboard and mouse, but
those were the common ones through the Mac ADB era.

Does it? I know the 3 pin miniDIN used on the Localtalk network has a
switch in the socket that conencts a terminating resistor, and which is
openned when the plug is inserted, but I've never seen any evidence of
this on ADB. But admittedly I've never tried to trace out schematics of
an ADB'ed Mac.

Perhaps that's what I'm thinking of - the switch goes with the 3-pin
miniDIN Localtalk connectors, not 4-pin miniDIN ADB connectors.

They do. The Plus was the first one with mini-DIN serial ports.
