I used to solo play 2-player Gauntlet for the PC this way, back around 1990.

In the 1980s it was pretty common to have 2-player games with both players on the same keyboard.

Edit: Spacewar (see https://archive.org/details/msdos_Spacewar_1985) is an example of a two-player-on-one-keyboard game, from 1985.

Me and my friends used to play 3 player simultaneously in D-Zone. Obviously we had to be kind with each other about space around the keyboard and about key presses. Still one of the best gaming experiences I ever had.
