Page "Burroughs Corporation" Paragraph 6

Burroughs developed a range of adding machines with different capabilities, gradually increasing in their capabilities.

A revolutionary adding machine was the Sensimatic, which was able to perform many business functions semi-automatically.

It had a moving programmable carriage to maintain ledgers.

It could store 9, 18 or 27 balances during the ledger posting operations and worked with a mechanical adder named a Crossfooter.

The Sensimatic developed into the Sensitronic which could store balances on a magnetic stripe which was part of the ledger card.

This balance was read into the accumulator when the card was inserted into the carriage.

The Sensitronic was followed by the E1000, the E2000, E4000, E6000 and the E8000, which was computer system supporting magnetic tape, card reader / punches and a line printer.
