TI Chips Users Group

While I was first exploring the comp.sys.ti newsgroup, I was pleased to find a post advertising that the TI Chips Users Group was still in existance. I was a member of the group back about 1984 or 1985, and was president for about 6 months before I went away to college.

For more information (corresponding memberships available), go to the TI Chips Info. page.
