Drawing gray rectangles is a very resource intensive operation. It is a wonder how a Pentium was able to draw also a 3D border around the rectangle.

There were some sick people who, in 4 Megs of RAM were also letting you choose colors while presenting a Win10/11 interface (Apollo) but those were some heretics.

Indeed. I've heard Elon is upgrading his Colossus computer just to experience dragging grey rectangles seamlessly.
