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 me some hints about the functions and keys of this mystery calculator. If you know more about the calculator or own a manual, please contact me.
| 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:
Digging deeper into the TMC098x calculator chips you'll locate an OEM-chip used on a TI-30 "clone" manufactured in Hong Kong:

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.
