@bnuuy @futurebird i'm struggling trying to come up with even one early home computer that had an integrated display and keyboard in a single device. the commodore pet maybe counts, though the display was separable, like the trs80. the apple 2 didn't have one, and obviously neither did the first apple.

a lot of the home computers were keyboards with an rf output that was expected to be hooked up to your television.

the original mac had the display integrated into the chassis, but not the keyboard.

i'm sure i'm missing some old computers (there were a lot of options back then!), but i wouldn't say the earliest home computers integrated screens and keyboards as one, nor that they were considered a single device.
