For a real antique, I am flying home with one of these:

Was my dad's, then a hand-me down I used in my first couple of years of high school, before getting a 286 laptop running DOS/Windows 3.x ... has sat unused in storage at my mom's for about 22-23 years.

Mine is quite the bit worse for wear; the RAMdisk/modem module is missing as are several keys. When I get in, will post a picture for comparison and when time permits, I will be checking through my junk box for a 6V AC adapter to see if it still runs at all.

Amazing battery life; ran 6-8 hours on the internal battery pack (4 nicads, very similar to what you'd see on some of the chunkier cordless phone handsets a few years ago.)
