Started a computer revolution?!
(from the soundtrack) "In 1982 the Sinclair ZX Spectrum was launched, a computer which gave a generation of school children their first introduction to computer programming and started a computer revolution in the UK and beyond."
Hogwash. The computer revolution was well under way already - think TRS-80, Apple ][, Acorn Atom, etc. not to mention all the earlier hobbyist kit from which they were derived. It would have continued whether or not the Spectrum was launched what with the BBC Micro, Commodore VIC/64, Amstrad CPC & PCW (ah! CP/M) and all the other many and varied options until the PC swept them away.
The Spectrum's only selling point was that it was inexpensive - 48 KB model for £175 at launch. But the price tag came only by seriously compromising functionality - no usable I/O except a rather dodgy edge connector directly onto the memory & I/O buses that positively promoted unreliability when you started trying to use peripheral modules, no hardware polyphony, no thought-through provision for different types of local or or networked mass storage, no proper layered OS/language/application separation, a slow BASIC interpreter that didn't support named procedures with parameters or local variable, a weird way of entering keywords to minimise key presses on that awful keyboard, no chance of touch-typing, no support for other programming languages and not even a built-in assembler.
(Anyone remember the Beeb manuals? It shipped with a nice think ring-bound "BBC Microcomputer System User Guide" with a complete BASIC and OS API reference as well as excellent tutorials including for the built-in assembler and you could get the awesome "BBC Advanced User Guide" with circuit diagrams and even more detail about the firmware. Sinclair Spectrum manual? Pah!)
