Ok, so the bad news is that one of my disks was completely hosed and one had damaged files. The good news is that the hosed disk was just my master IS-DOS disk and I had a backup (and you probably have this stuff anyway). The better news is that both of the EGI disks were ok.
I've zipped up the 5 disks I had and attached it. I'm going to go out on a limb and guess that no one is going to want to pursue me through the courts for piracy at this point!
I'm afraid I don't have any documentation or a working Enterprise (my power cable is FUBAR but the machine itself might be ok) so I can't help you out. I'm sure you'll figure it out though.
It's funny, I was looking at some old posts about the EGI and it has something of a mythical reputation. I'm glad I can finally make it real - I hope it works!
Let me know how you get on.
