Apple Lisa...?

I will soon be aquiring an Apple Lisa... whee! So in the mean time, I'm trying to find out as much info about them as I can. There are several greal Lisa web sites, but I still have some unanswered questions. - Does anyone here own one? - Anyone know of any Lisa-specific mailing lists? - Has the copy protection on original system disks and program disks ever been cracked? (for those that don't know, the first time an original disk is used in a Lisa, it apparantly stamps the disk with its serial number, preventing other Lisae from using it). - Are there any other "workshops" other than Pascal Workshop, Cobol Workshop, and BASIC Workshop? A nice C Workshop would be handy, but the language hadn't really fallen into general use by micro users at that time. - Was any 3rd party software ever released for the Lisa? - Why did Apple decide NOT to put memory protection & preemptive multitasking in the Mac when the Lisa had it? I guess that's enough for now... :) If there actually are any Lisa owners out there, I'll probably have plenty of questions for you once I get the thing two weeks from now. Luckily, it comes with a complete Office 7/7 setup & a Profile drive, so the copy protection isn't a problem. chris
