I'm no expert on this, I think the only 68k Mac that can be brought forward
to a PPC is the Quadra 800, and that takes saving the upper case, throwing
out the rest and putting the upper case on a PM 8500. The back and the
bottom will not work on a 8500. (I tried years ago, and bought the mobo and
higher output power supply, but could not find the case bottom.)
Well I hate to say it but you're totally wrong Brent.
Yes that is one way of upgrading a 68k Mac (it also works on 840av Quadras but I will *personally knock down you door* if I catch you trying it with one - they are a masterpiece in their own right and shouldn't be tampered with...) but it's far from the only way.
Apple and third party vendors did a card for the 68040 socket that carried a 601 and the 68040. This gave the option (via a control panel) of running the machine as a PPC. The card fitted all LC/Performa 47x and 57x machines (and the 580) as well as 63x and Quadra 610, 650 and 660av. 3rd Parties also did cards for Mac II machines.
In short there are lots of upgrades available for all sorts of 68030 and 040 machines, and non as barbaric as the original suggestion!
The LCs would be great as a word processor or for spread sheets if you kept
the apps at a low enough level. Or maybe even fine for "home" automation.
(My goal.)
My 840av does video capture at [EMAIL PROTECTED] Oh yeh i know that's cheating 'cause it's an AV machine with a 40MHz CPU ;)
LC475s make great web/FTP servers on LANs. Using MacHTTP you could have folders on the machine for each person and they could have a site each.
But the 68k will limit you to 8.1 and below, I do not think that you will ever get them to OS X.
My 7100cx (it's a 7100 in a IIcx case with a 5GB 2.5" hard disk - don't ask!) runs 8.1 and routinely links to my Mac OS X iMac with ease. OS 8.0 and later support Appletalk/IP which uses Appletalk over standard TCP/IP. This allows the to access OS X.
The 68k Mac can not use HFS+ format needed for OS X.
It can use HFS+ but CAN'T boot off it.
At Sys 7.1 and MS Works 2.1, I can boot the LC 16 MHz, and launch Works,
much faster than my PM 7600/ G4 800MHz can even just boot.
That'll be OS 9 bloatware dragging the 7600 down maybe ;)
You would probably need to go to Word 5.1 for compatibility, and I do not know
off-hand which OS is needed to support that, but it is probably much larger
than 7.1.
Word 6.0 saves to the same format as modern versions of Word and runs on anything from 7.1 upwards.
They should integrate over Ethernet fine with X from somewhere in System 7.
I, and others, have managed it from 6.0.8 to OS X (10.1.x). I have yet to repeat the trick with 10.2 sadly.
I'm slowly working on getting a LC to Ethernet with a OS X LAN.
There's a neat 'hack' for OS X that opens up
I tried an Asante PDS Ethernet card, but besides not fitting inside the case, it drew too much power for the PS.
WHAT?? You probably didn't have an LCPDS card, in which case you risked totally killing the Mac!
This was the one that has RJ-45, AUI, and the co-axial Enet, or vice versa.
That definitely isn't an LC PDS card. There is only room on the LC back plate for RJ-54 and CoAx connectors, or a single AUI or AAUI socket.
The limitation that I am finding is that the LC, as is, can only be
upgraded to 10 Mb and with the 40 Mb HD it comes with, I have to stay below
7.5.1. I will probably upgrade the HD when I can get it to connect by
Ethernet.
I'd hesitate to even run System 7 on an LC. 6.0.8 is much faster and slicker.
Here is an excellent site for info on upgrading a 68k Mac so you do not have
to reinvent the wheel.

*JOKE* Yay for pickle's FAQ (retires to flame proof bunker) ;) *JOKE*
The upgrade sounds like a good project for one of your students. For me it
is a "back burner" project. In case that idiom does not translate well, it
means slow cooking or when ever I have time to work on it.
I have lots of these. Every now and again I pick up a project and play with it, then put it down again.
