The 301 (better known as the Type IV) Accounting Machine was the first card-controlled machine to incorporate class selection, automatic subtraction, and printing of a net positive or negative balance. Dating to 1928, this machine exemplifies the transition from tabulating to accounting machines. The Type IV could list 100 cards per minute.

The Gamma 3 was an early electronic vacuum-tube computer.It was designed by Compagnie des Machines Bull in Paris, France and released in 1952.. Originally designed as an electronic accelerator for electromechanical tabulating machines, similar to the IBM 604, it was gradually enhanced with new features and evolved into a first-generation stored program computer (Gamma AET, 1955, then ET, 1957).
The 402 could read punched cards at a speed of 80 to 150 cards per minute, depending on process options, while printing data at a speed of up to 100 lines per minute. The built-in line printer used 43 alpha-numerical type bars (left-side) and 45 numerical type bars (right-side, shorter bars) to print a total of 88 positions across a line of a report.
The 407 rented from $800 to $920 per month ($10200 to $11800 per month in 2023 dollars), depending on the model. [3]Its print mechanism was used in the IBM 716 introduced in 1952 with the IBM 701 computer, and the 716 was used with many machines in the IBM 700/7000 series.
Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting.

Powers-Samas machines detected the holes in punched cards mechanically, unlike IBM equipment where holes in punched cards are detected by electrical circuits. Pins that could drop through round holes in punched cards were connected to linkages and their displacement when a hole was present actuated other parts of the machine to produce the desired results.
