It's going to Tahoe which is probably a good thing. He's got more Commodore UX stuff and in better condition, plus a goal of preserving it all - which for something as unusual as this find is highly important.
As far as 3J is concerned, v1.1 was itself pretty buggy. The main interest for me would be, hey, it's a beta...maaaaaybe there's some more stuff for debugging, some more source code, maybe even some C= bug submission tool? I bet there's at least a few interesting goodies in there.
I'd love to hook up with a 2.1 tape and "legit" patch disk. Sure I've got homegrown tapes but it would be oh so perfect next to my copy of the Unix-Haters Handbook. :-)
Best of luck with the auction, and to the bidders :-D
