The Ottawa TI-99/4A User's Group (OTIUG) was formed in 1980 to provide a forum for persons in the Ottawa, Canada area who had bought a Texas Instruments TI-99/4A Home Computer after its release in 1979. In 1981 the OTIUG started to support the TI-99/4A and later also supported the Myarc Geneve. During the fifteen years of its existence the OTIUG had many accomplishments of its own and helped many of its members go on to make their own significant contributions to the TI community.

The OTIUG 'NEWSLETTER' was very well supported by many of its members who contributed articles on a variety of subjects. It enjoyed wide distribution because of out of town members and through exchanges with other user groups. Some significant articles included:


The OTIUG supported the development of a number of programs and distribution of some of them as Freeware packages. Some of these included:


The OTIUG had an extensive disk library available to its membership. The catalogue of their library was maintained using Marty Kroll's CATLIB program.

For a long time the OTIUG BBS Sysop was Peter Arkin and he even continued on for a while after the group disbanded.

Membership in the OTIUG peaked at 163 members at the end of 1987 and had declined to 23 members when it disbanded in April 1995.

From 1986 to 1993 the OTIUG held a number of annual 'TI-Fest' fairs that were widely attended by TI99ers from many parts of Canada and the United States. The 2nd TI-Fest held at an Ottawa high school on May 17, 1987 was typical of these fairs and included the following highlights:

In Walt Howe's report on this TI-Fest he says:"These Canadians include some remarkable people, and it is the people who make these events, not the hardware and software".

In addition to OTIUG members already mentioned above, others wrote and some have continued to write very useful programs for the TI community.

The Ottawa TI-99/4A User's Group was an above the average TI-99 user group that contributed much to the TI community and also provided an atmosphere for many of its members to do the same.

Inducted into the TI99ers Hall of Fame on July 25, 2013.
