Five other innovative Casio products G-Shock champion Kazuo Kashio will be remembered by
A portable computer with – wait for it – 8KB of memory, a classic waterproof stopwatch, the first digital camera: in the week Casio co-founder Kazuo Kashio died, we look back at five of his company’s most innovative products

The business executive will be remembered for his role in popularising the G-Shock, a watch famed for its resistance and multimodal functions. While it is arguably Casio’s best known product, the G-Shock isn’t Casio’s only innovative invention.
These are five other Casio products that will be remembered for their innovativeness.

1. PB-770 portable computer
Released in 1984, the PB-770 was one of Casio’s smartest inventions. Released just a year after Internet Protocols (known as IP) were fully activated, the 114mm-wide device could store up to 8KB of data, and up to 32KB with an extension. Its functions included a built-in calculator, and it came with a portable printer. It was an ideal tool for researchers.
