 During development, the ZX Spectrum was referred to as the ZX81 Colour and the ZX82. The rename to Spectrum was done to highlight the machine's new color capabilities.
+The Spectrum was released as eight different models with different capabilities for their budget, going from the entry-level model only having 16KB RAM to the high-end +3 with 128KB RAM and built-in floppy disk drive.
+Model list:
+  * ZX Spectrum 16K
+  * ZX Spectrum 48K
+  * ZX Spectrum+
+  * ZX Spectrum 128
+  * ZX Spectrum+2
+  * ZX Spectrum+2A
+  * ZX Spectrum+3
+  * ZX Spectrum+2B
+  * ZX Spectrum+3B
+The Spectrum was a cultural phenomena to British culture. The Spectrum's creator, Clive Sinclair, was knighted in 1983 for his services to the British industry. Spectrum game development continues to this very day.
