@kdfrawg The first colour Mac I had was my school-teacher sister's no longer needed (they'd gone PC) Performa 5400. That had a variable screen. Depending on how it felt at the time it would be either the expected 15-inch or it would shrink to about 9-inches.
When the display died I got my first G3 iMac.
