We bought and networked several of these at the office. Once we had all we needed I recall them being about $4500 a piece.
Coleco Adam 1983 Was my first venture with a computer and a printer. I seem to remember it was rather cheap. But in truth the $100.00 Times Sinclare was my first real computer. I did have a video game that ran tiny Palo Alto Basic with a keyboard that had three values to each key on the pad. No storage whatsoever tho they claimed you could back it up to any tape recorder, never had any success with that tho.
