The keyboards of some early computer terminals, including the Teletype Model 33 ASR and Lear-Siegler ADM-3A, the Apple II and a few Apple Keyboard models retained the Control key where PC/XT first had it; CAPS LOCK was either absent on these device or was placed elsewhere. This layout was preserved for later workstation systems and is often associated with Unix workstations. Keyboards from Sun Microsystems came in two layouts; "Unix" and "PC-style", with the Unix layout having the traditional placing of the Control key and other keys. The Amiga computers all had both the Control key and CAPS LOCK key in this spot at half the width.
