Hewlett-Packard 97 printing calculator, desktop electronic programmable, with instruction manual and Standard and Statistical program packs, soft carrycase and ac adaptor, made in Singapore, introduced 1977, alongside the pocket HP 67 as a step forward in both the power and portability of so-called 'personal' computers. They were described by Hewlett Packard 'A major leap forward in fully-programmable personal calculators. These are the most powerful personal calculators Hewlett-Packard has ever made.' The machines had a variety of design improvements based on Hewlett Packards 20 series of calculators, ranging from full-merged keyboards to more memory and better program editing. The HP 67 and HP 97 were functionally identical, but the HP 97 had a printer and a larger case and battery pack. The HP 97 was manufactured from 1976 until 1982. This machine was made in Singapore.
