When I worked in a S& L in the 90's DOS Era, We had IBM PC's with a cloth antiglare screen, that was attached to the "Green on Black" Monochrome Monitor. This was also in the early days, when copier's were expensive. Many of the Secretaries and Clerks used Mimeograph machines, that had Stencils that were created on typewriters. When the stencils had a an error they used a special blue correction fluid. You guessed it. I had to cut the anti-glare screen cloth off of the monitor, because there was no way to remove the correction fluid from the screen.
