Well, I was making progress - I think the issue was that it needed to be unpacked in old Stuffit Expander, rather than on my Pismo - but on first restart, this process seems to have fried the hard drive on my 5300, I am now getting the flashing disk with question mark. I think I am going to end my explorations here with this hack and leave things the hell alone... I will have to see if the disk is really dead, or just needs an OS reloaded. Pooh! I will treat these as standalone machines, not internet playthings... It's just too hard trying to make these "95-'96 laptops play nicely. I have definitely become an OS X kind of guy, things just work better!
