Choosing the Right Tool

HP were marketing their 10,40,80,100 and 200 series comprising a range of calculators and computers. This brochure included sales and technical information designed to aid the purchaser in making an informed choice from the models available

The 10 series were labeled Professional Calculators and included the HP-10C, HP-11C, HP-12C, HP-15C and the HP-16C - each optimised for a particular function.

The series 40 Handheld Computers included the HP-41, the HP-41CV, the Series 40 Plotter Module and it’s associated HP 7470A Graphics Plotter.

In 1982, the Portable Computers 70 series included only the venerable HP-75C, offering as it did 16 kbytes of RAM, expandable to 24K.

The Series 80 Personal Computers included the HP-85 and HP-87. Both were compact desktop models with built-in CRT screens. They offered cassette storage and a thermal printer. It is interesting that the case study, of a business owner called Ann, featured the HP-86 Personal Computer - which does not form part of the product offering. The HP-86 used the more familiar system unit and separate display.

Series 100 Personal Office Computers offered the HP-120 and HP-125, both of which could act as terminals to an HP-3000 mainframe. Both computers made use of dual Z80A microprocessors, one as the CPU and the other as a display processor. There really isn’t much new in the computer world, except the hype.

Personal Technical Computers included only the Series 200 model 16, based on an 8 Mhz 68000 microprocessor. Maximum memory was 768 Kbytes. The brochure notes ‘A hardware/software package called Shared Resource Manager (SRM) can link as many as 11 Model 16s to one printer and one mass storage device, creating significent economies as a business expands’. A SAN, anyone?

Available software included Visicalc, Wordstar and BASIC. Mention is made of Fortran, Cobol, Pascal and Forth.
