Thats kinda what I figured.. These were the systems that were availalbe on a lot of test equipment sites a couple years ago (like testequity.com).. They all came from a large test equipment wholesaler in baltimore that bought about 200 of them from an air force base in TX a long while ago from a DRMO sale, back when they weren't public. They were selling them to a lot of large companies like IBM and most of the toy manufacturers all bought some as well.. After that some went to other test equipment dealers and when they were down to 10 or so left they were selling them for around $2k for a complete set in 1999. I assume they are out of them now.. I saw a pile of them in thier warehoue and the owner gave me the full story on them... they didn't have any keyboards, monitors, or I/O pods sitting around :( The systems did come with 2 complete sets of manuals though.. no TL/1 manuals of course..
