Intel 8080

97 bytes added, 23 April
/* Evolution */
The 8080 ultimately led to the machine code-compatible, but more powerful clone Zilog [[Z80]], which was of course also used in the Amstrad [[CPC]] and Sinclair [[ZX Spectrum]] among others. (Note that 8080 assembly language looks different from Z80 mnemonics; e.g. the Z80 uses <tt>LD</tt> whereas the 8080 has <tt>MOV</tt> and several other commands.)
Meanwhile Intel produced the 8085, an improved, backward-compatible version of the 8080, with refinements to power consumption and integration.[https://heavydeck.net/post/i8085-compatibility-grid/ i8085 compatibility grid with Z80 & GBZ80]
