HP-75

The HP-75C and HP-75D were hand-held computers programmable in BASIC, made by Hewlett-Packard from 1982 to 1986.

The HP-75 had a single-line liquid crystal display, 48 KiB system ROM and 16 KiB RAM, a comparatively large keyboard (albeit without separate numeric pad), a manually operated magnetic card reader (2×650 bytes per card), 4 ports for memory expansion (1 for RAM and 3 for ROM modules), and an HP-IL interface that could be used to connect printers, storage and electronic test equipment. The BASIC interpreter also acted as a primitive operating system, providing file handling capabilities for program storage using RAM, cards, or cassettes/diskettes (via HP-IL).

Other features included a text editor as well as an appointment reminder with alarms, similar to functions of modern PDAs.

The HP-75D (1984–1986) added a port for a bar code wand, often used for inventory control tasks.

The HP-75 was comparatively expensive with an MSRP of $995 ($2,014 in 2005) for the 75C or $1095 ($2,058 in 2005) for the 75D, making it less popular than the cheaper successor model, the HP-71B.

Case IH

Case IH is a brand of agricultural equipment. It was created in 1984 when Tenneco bought selected assets of the agricultural division from International Harvester and merged it into its J.I. Case Company. Today Case IH is owned by CNH Industrial, which in turn is financially controlled by the Italian firm Fiat Industrial.

Case IH offers agricultural equipment, financial services, as well as parts and service support for farmers and commercial operators through a network of dealers and distributors.

Productivity enhancing products include tractors; combines and harvesters; hay and forage equipment; tillage tools; planting and seeding systems; sprayers and applicators; and site-specific farming tools. Case IH has won many AE50 awards from the American Society of Agricultural and Biological Engineers, ASABE, for their products.

Some of Case IH’s most famous equipment models include Axial-Flow combines, Magnum tractors, Steiger and Farmall.

History

Case IH history began when, in 1842, Jerome Increase Case founded Racine Threshing Machine Works on the strength of his innovative thresher. In 1869 Case expanded into the steam engine business and, by 1886, Case was the world’s largest manufacturer of steam engines. The company's founder died in 1891 at the age of 72.
