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.
A new type of wobbulators was developed and implemented in the mid-1980's at Singer-Link Flight Simulation. As a result of the layout of the CRT's checklists and other text on the control panels, users had to scroll through them one line or page at a time to finish.
