Origins of term "laptop" computer

Using some other folks' research from another thread on another mailing list of the same debate (was an interesting read as well). http://mail.computerhistory.org/pipermail/inforoots/2006-February/001719.ht… some of the same 1984 articles we've found in googles archive of the term "laptop". He also I believe is the one who pointed out the MCM/70 system which is amazing. http://mail.computerhistory.org/pipermail/inforoots/2006-February/001712.ht… Evan's previous searching results which he likely rigorously searched through at the library. He found the same January 1984 byte article using the term. He also found the 1982 reference of the HX-20 (and apparently also the TI-CC40 as a notebook which is also an interest conclusion that perhaps the term was end-user and notebook or "notebook sized computer" may have been first before the probably less flattering "lap-top" or "lap-held" computer. At that time I think Evan (now Evan has a LOT of experience and this might have been pre-M.A.R.C.H/museum phase so I'm sure lots has been learned) was leaning towards the HX-20 being the first laptop or advertised device as a notebook. Later he found references to the Grundy NewBrain system ( http://mail.computerhistory.org/pipermail/inforoots/2006-February/001723.ht…) which depending on the release date could be before a lot of the other published systems but I'm not sure if their advertising ever used the term. Two categories now though. The technicality of what device was first as a laptop computer or who was the first to coin and use the term (which I think is fair to set the expectation of what rule applies to the device in question i.e. does it have to be battery powered?).
