A Sinclair ZX Spectrum+, from the mid-80s. It is a black, rectangular computer with a QWERTY keyboard layout. All of the keys have additional BASIC commands, and there are keys such as SYMBOL SHIFT and EXTEND MODE which don't exist on modern keyboards, that make it clear this was a keyboard designed with programming in mind. It is beautiful. The CAPS LOCK key is a small button between shift and z.
