IBM5100 OS apl/basic
The IBM 5100 is based on a 16-bit processor module called PALM. The IBM 5100 Maintenance Information Manual also referred to the PALM module as the controller. The PALM could directly address 64 KiB of memory. Some configurations of the IBM 5100 had Executable ROS and RAM memory totalling more than 64 KiB, so a simple bank switching scheme was used. The actual APL and BASIC interpreters were stored in a separate Language ROS address space which the PALM treats as a peripheral device. -

Apple Macintosh Portable
Featured a fast, sharp, and expensive black and white active matrix LCD screen in a hinged design that covered the keyboard when the machine was not in use. The Portable was one of the early consumer laptops to employ an active matrix panel, and only the most expensive of the initial PowerBook line, the PowerBook 170, used one, due to the high cost. The cursor pointing function was handled by a built-in trackball that could be removed and located on either side of the keyboard.
