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.) 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.) But the 68k will limit you to 8.1 and below, I do not think that you will ever get them to OS X. The 68k Mac can not use HFS+ format needed for OS X. 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. 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. They should integrate over Ethernet fine with X from somewhere in System 7. I'm slowly working on getting a LC to Ethernet with a OS X LAN. I have an extra Farralon PDS Ethernet card and can tell you where to find another in Canada, and guarantied refurbished RAM in the US, if you need it. I tried an Asante PDS Ethernet card, but besides not fitting inside the case, it drew too much power for the PS. This was the one that has RJ-45, AUI, and the co-axial Enet, or vice versa. 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. Here is an excellent site for info on upgrading a 68k Mac so you do not have to reinvent the wheel. <http://macfaq.org/index.shtm 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.
