Figure 1.  A printed circuit board notched like your ZX computer's circuit board and the OpenSpand edge card connector with a matching key in position 3.  The notch and the key must be aligned to insert the connector to the PCB. WARNING:  If the key ever falls out of the edge card connector, you need to replace it before connecting your Open Spand.	Figure 2.
