Olivetti PC128 internal key

This model reproduces the internal structure of the keyboard keys of the Olivetti PC128S and the Thomson MO6. Specifically, it replicates the fastening mechanism located under the keys, including the side tabs that ensure their stability. However, these tabs tend to deteriorate or break over time, causing an abnormal lowering of the key and excessive lateral movement. Although the key remains functional, the lack of adequate support compromises its ergonomics and makes typing less comfortable.
