An accounting machine, or bookkeeping machine or recording-adder, was generally a calculator and printer combination tailored for a specific commercial activity such as billing, payroll, or ledger. Accounting machines were widespread from the early 1900s to 1980s, but were rendered obsolete by the availability of low-cost computers such as the IBM PC. This type of machine is generally distinct from unit record equipment (some unit record machines were also called accounting machines). ==List of Vendors/Accounting Machines == * Burroughs Sensimatic * Burroughs Sensitronic * Burroughs B80 * Burroughs E103 * Burroughs Computer F2000〔 * Burroughs L500 * Burroughs E1400 Electronic Computing/Accounting Machine with Magnetic Striped Ledger〔(Burroughs E1400 )〕 * Dalton Adding Machine Company〔 * Electronics Corporation of America: Magnefile-B * Electronics Corporation of America: Magnefile-D〔 * Elliott-Fisher〔 * Federal Adding Machines〔 * IBM 632 * IBM 858 Cardatype Accounting Machine * IBM 6400 Series * Laboratory for Electronics: The Inventory Machine II (TIM-II)〔 * Monroe Calculator Company: Model 200 * Monroe Calculator Company: Synchro-Monroe President〔 * Monroe Calculator Company: Monrobot IX〔 * NCR Post-Tronic Bookkeeping Machine - Class 29〔 * NCR Compu-Tronic Accounting Machine〔 * NCR Accounting Machine - Class 33〔 * NCR Window Posting Machine - Class 42〔 * Olivetti: General Bookkeeping Machine (GBM)〔 * J.
