IBM Typewriter Guide

Historical orientation

IBM introduced the Selectric in 1961.

IBM describes it as the most successful electric typewriter in history and reports a dominant share of the electric typewriter market by 1978.

Selectric machines require different service knowledge from manual portables.

Model families to learn

• IBM Selectric I
• IBM Selectric II
• IBM Correcting Selectric
• IBM Wheelwriter and later electronic machines

Identification clues

• Confirm the exact Selectric generation and whether correction is built in.
• Inspect the cord and power system before plugging in an unknown machine.
• Type elements are interchangeable, so the installed typeface may not be original to the machine.

Before buying

Ask for the serial number, a current typing sample, photographs beneath the ribbon cover, and a clear explanation of any service. Compare the exact family rather than treating every IBM as equivalent.

Useful comparison terms

Add the model, body generation, color, keyboard language, case, working status, or service terms to your search. For electric machines, include the exact generation and correction system.
