Another implementation of wobbulators were designed and implemented in the mid-1980's at Singer-Link Flight Simulation. It was determined that due to the orientation of the CRT's checklists and other similarly formatted text at the simulator's control panels created a situation where checklists had to be scrolled through, line-by-line or page-by-page, to complete.
At Singer-Link Flight Simulation, a new implementation of wobbulators was created in the mid-1980's. This led to an issue with how checklists were displayed on the simulator's control panels, necessitating scrolling through them one line or page at a time.
