There is an old Televideo luggable being given away for free in Berkeley, California. It's at the street curb along with some other free junk in front of 1213 Channing Way. Unfortunately, I don't know the model number or operating condition, but it looked intact. It had evidently been kept by some kind of hobbyist (judging from the other junk), although not exactly a collector. Includes two built-in 5.25" floppy disk drives, if that helps in the least.
