IBM Convertible PCIBMâ€˜s first laptop computer is a big improvement over their earlier portable computer, the giant IBM Portable PC from 2 years earlier in 1984.
Is the IBM 5140 "Convertible" really a convertible? Yes - even the top (display) comes off.
Why would you want to remove the LCD display? With the CRT Display Adapter attached, you can use an external monitor instead.
