Akeyboard computer is a computer which contains all of the regular components of apersonal computer, except for a screen, in the same housing as the keyboard. The power supply is typically external and connects to the computer via anadapter cable. The motherboard is specially designed to fit inside, and the device is larger than most standard keyboards. Additionalperipheral devices such as amonitor are connected to the computer via externalports. Usually a minimum of storage devices, if any, is built in.
Most home computers produced during the late 1970s and 1980s were keyboard computers, theZX Spectrum and most models of theAtari ST,Xiao Bawang,Commodore 64,Apple II, andAmiga being prime examples. While this form factor went out of style around 1990 in favour for more modulardesktop setups, some notablex86 keyboard computers have been built, like theOlivetti Prodest PC1 in 1988[1] and theSchneider Euro PC Series between 1988 and 1995.[2]
Newer computers to employ this form factor include theCommodore 64 WebIt by Tulip, theAsus Eee Keyboard,[3][4] which usesIntel Atom processors andSolid-state drive,[5] and the unreleased Commodore Invictus PC.[6] In November 2020,Raspberry Pi Foundation announcedRaspberry Pi 400, a modified version of their previous Raspberry Pi 4 housed entirely within a keyboard.[7] Similarly, in December of 2024, theRaspberry Pi Foundation released the Raspberry Pi 500[8] and, in September of 2025, released the Raspberry Pi 500+,[9] both based on theRaspberry Pi 5.
