Geniac was an educational toy sold as a mechanical computer designed and marketed by Edmund Berkeley, with Oliver Garfield from 1955 to 1958, but with Garfield continuing without Berkeley through the 1960s. [1]
The Z2 used the mechanical memory of the Z1 but used relay-based arithmetic. The Z3 was experimentally built entirely of relays. The Z4 was the first attempt at a commercial computer, reverting to the faster and more economical mechanical slotted metal strip memory, with relay processing, of the Z2, but the war interrupted the Z4 development.'

A digital pen is an input device which captures the handwriting or brush strokes of a user and converts handwritten analog information into digital data, enabling the data to be utilized in various applications. This type of pen is used in conjunction with a graphics tablet, tablet computer, smartphone or digital notebook.

The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. [2] [3] It was first described in 1837 as the successor to Babbage's Difference Engine, which was a design for a simpler mechanical calculator.
