HP-150 (aka HP Touchscreen or HP 45611A) was a compact, powerful and innovative computer made by Hewlett-Packard and introduced in Las Vegas at Comdex fall trade show on November 28,1983. It was based on the Intel 8088 CPU and was one of the world's earliest commercialized touch screen computers. Like other "workalike" IBM PC clones of the time, despite running customized MS-DOS versions 2.01, 2.11 and 3.20, the machine was not IBM PC DOS compatible. Its 8088 CPU, rated at 8 MHz, was faster than the 4.77 MHz CPUs used by the IBM PC of that period. Using add-on cards, main memory could be increased from 256 KB to 640 KB. However, its mainboard did not have a slot for the optional Intel 8087 math coprocessor due to space constraints. An HP-150 with an optional hard disk was called HP Touchscreen MAX.
The computer's screen was a 9-inch Sony CRT surrounded by infrared emitters and detectors which detected the position of any non-transparent object that touched the screen. In the original HP-150, these emitters and detectors were placed within small holes located on the inside of the monitor's bezel (which resulted in the bottom series of holes sometimes filling with dust, causing the touchscreen to fail until the dust was vacuumed from the holes).
