This was the first HP 38E made in Hewlett Packard’s Singapore Factory. It was presented to Mr. Hon Sui Sen (his name engraved on the top of the calculator) in 1978. This calculator is currently on display in National Museum of Singapore on loan from the Hon Family. The accompanying display plate wrote, This was the first calculators produced in Hewlett-Packard (HP) factory in Singapore, an appropriate gift to be presented to Hon, the Minister of Finance.

The HP-01, code-named “Cricket,” was not a successful product for HP. It was too bulky and heavy, and HP sold it though upscale jewelry stores. But miniaturizing the math functions was quite an engineering feat, and when HP discontinued manufacturing the HP-01, its inner workings were destroyed so no one would copy the extraordinarily small package engineering. The HP Archives has a few of the remaining elements. The HP-01 “calculator watch” performed more than three dozen functions to manipulate and interrelate time, calendar and numeric data.
