{{Information|Description=ZX80 circuit diagram, accurately re-drawn as vector graphics by Grant Searle in January 2009 from Sinclair's original. Component designators and values match Sinclair's own drawing: C1/C2/C4/C5/C6 47 nF on the 5 V rail, C8 22 uF 16 V on the unregulated input, C10 1 uF in the R21 power-on reset network, IC22 the 7805 regulator, IC3/IC4 the 2114 static RAMs and IC2 the 8332 ROM.
