IBM Electric typewriter

|
The IBM Electric typewriters were a series of electric typewriters that IBM manufactured, starting in the late 1940s. They used the conventional moving carriage and hammer mechanism. Each model came in both Standard and Executive versions; the Executive differed in having a multiple escapement mechanism and four widths for letters, producing a near typeset quality result.
| Model | Year |
|---|---|
| IBM Model 01 | 1933 |
| IBM Model A | 1949 |
| IBM Model B | 1954 |
| IBM Model C | 1959 |
| IBM Model D | 1967 |
Modified Standard versions of the A, B, and C models were commonly used as "console typewriters" or terminals on many early computers (e.g., JOHNNIAC, IBM 1620, PDP-1). Following the introduction of the IBM Selectric typewriter in 1961, which was much easier to interface to a computer, these typewriters were rarely used anymore as "console typewriters" or terminals.
