The 10C was a basic scientific programmable calculator. While a useful general purpose RPN calculator, the HP-11C offered twice as much for only a slight increase in price. Designed to be an introductory calculator, it was still costly compared to the competition, and many looking at an HP would just step up to the better HP-11C.

Like the HP-28C, this model used the "open-book" physical design. Functionally a direct predecessor to the HP-48 series, which returned to a more traditional physical design based on the HP-41. HP-29C: 1977 Programmable calculator with RPN. Included a programming language with looping and branching. An inexpensive variation on the 19C printer ...
PowerHouse is a byte-compiled fourth-generation programming language (or 4GL) originally produced by Quasar Corporation (later renamed Cognos Incorporated) for the Hewlett-Packard HP3000 mini-computer, as well as Data General and DEC VAX/VMS systems. It was initially composed of five components:
Rocky Mountain BASIC, created at HP, now transferred to Keysight; for HP 9000 and other platforms; often used with HP-IB instruments VSI BASIC for OpenVMS , created at DEC, and previously known as HP BASIC for OpenVMS prior to the transfer to VSI; for the RSTS, VMS, PDP, VAX, Alpha, and Integrity platforms
