Many computers of the late 1970’s and early 1980’s consisted of a keyboard with the CPU and other major components built-in. The Commodore Vic-20, 64, Atari 400, 800 & 800 XL, TI-99/4A, and the Apple II are just a few examples of this form factor. The Coleco ADAM was basically the beginning of a trend that is still seen today; a console or tower with separate keyboard. Usually you can set the monitor on top of the console, but that was not a good idea with the ADAM.
The top of the ADAM has a removable lid to access the tape drives and expansion slots. As a result, the lid isn’t built to hold a classic television set or monitor (would bend the lid). Remember, CRT tubes were pretty heavy. So this was always an issue when setting up my ADAM. Here are a few examples of how some others set up their ADAMs.
