Teamhair is a monowidth font based on the face used on the old Sears Tower Gaelic manual typewriter.

Teamhair was first digitized in 1993 by Michael Everson and originally used the MacGaelic character set on the Macintosh platform, and ISO/IEC 8859-14 on the PC.

In 2008 Teamhair version 3 was released in OpenType format, completely compliant with Unicode encoding and with an extended character set.
