IBM 6091 monitors

Hello - I pulled 2 IBM 6091 19" monitors out of the trash. I think they were used on their power pc computers. I need info on this monitor, such as resolution, refresh rate and what are the white and black bnc connectors for. Any help is appreciated. john -- ************************************************************************ * * * * John Ott * Email: jott(a)saturn.ee.nd.edu * * Dept.
