About Terminal Madness
Terminal Madness started out as a Computer Bulletin Board, ( BBS ) back in the early 90's. Fascinated that one could get all the information they ever wanted "on line", for FREE, the "BBS" was named Terminal Madness.
Now, about 22 years later, that fascination with computers and information continues.
From the USA, to the Dominican Republic, to Curacao and back to the USA.
