A few months ago when you bumped this I decided to check out how many there were. I wasn't sure whether it's okay to post in these threads unless you're offering a name, and then I forgot all about it, but since I'm reminded of it again, others have posted, and people still don't seem to know what it's about, here's the list of all LLL.com from the 80s, from oldest to most recent (it shouldn't have changed since I don't think any of these have dropped since March):
bbn.com,mcc.com,dec.com,sri.com,ibm.com,sun.com,att.com,gmr.com,tek.com,fmc.com,
isc.com,nsc.com,bdm.com,nec.com,ray.com,gte.com,amd.com,das.com,tti.com,cgi.com,

Since there are only 119, and Sky, BBC, IBM, AMD, JVC etc are obviously not going to sell, it shouldn't take too long to contact owners who may be interested in selling.
Hope this is some help, or at least you're okay with it being posted. Good luck.
