The
Goulds Pumpulator was one of the early customized calculators produced by Texas
Instruments. Basically this calculator represents a Business
Analyst-I but was changed with a custom designed program memory to do be used as a pump calculator for use with
the English system of measurement. A similar
approach was later realized by Jeppesen Sanderson with their Flight Computers,
e.g. the Avstar.
Dennis Belillo gave us some hints about the functions and keys
of this mystery calculator.
| psi = pounds/inch squared 1 psi = 70.3089 grams/cm. squared atmospheric pressure is +/- 15 psi at sea level hp (I understand that there is a measure of work called the metric horse power) 1 horse power (as God intended them to be) = 1.0143 horse power metric and 1 hp = 632,800 calorie, grams/hour gpm = gallons / min therefore 1 gpm = 3.7853 liters per minute |
Simply by comparing the designation of the integrated circuits
of the entry line "Majestic" calculators, you'll get the all members
of this family:

TMC0980 Goulds Pumpulator uses a custom
design ROM (CD9801) Digging deeper into the TMC098x calculator chips you'll locate an OEM-chip used on a TI-30 "clone" manufactured in Hong Kong: TMC0985 Amelia Scientific 2001 |
With the introduction of the TI-58 Texas Instruments created the Solid State Software Modules to customize calculators. Have a look onto the insurance fee calculators from Agrippina, Allianz, Lloyd, LVM, Nordstern or Victoria.
