Other key parts include the LA15-302, TMS4764, 74LS260 and 74HC04. By type, the board carries 37 resistors, 10 diodes, 9 transistors, 8 capacitors, 4 ICs and 3 connectors.
From the project
Sinclair ZX Interface 1 Sinclair Routing
This is Kicad 9 project of the Sinclair ZX Interface 1 that uses the same routing and PCB dimensions as the orignal. A raw board was scanned and the top and bottom side images were imported into Kicad. This gave the board outline along with the position of components and the track layout. The schematic available from the Service Guide was then redrawn in Kicad and used to recreate the PCB and to verify that the routing was correct.
