News.com have an interesting article interviewing several notable people in the IT industry asking ‘What was your first computer?’. The answers are surprisingly varied, from the obvious first IBM PC, Apple II, to Commodore 64.
My first computer we had at home was a Sinclair ZX Spectrum, an 8 bit machine with 48k RAM and 16 colors (8 in two shades). It was and still is the only computer I know of on which you couldn’t type directly, meaning that all the keys had an assigned keyword in BASIC. When you pressed a key it output that keyword to the screen (a TV), and different variations from the same key depending on the context in which it was pressed, or due to a combination of control keys.
