I worked at Lexidata from 82-84. They should have been up there with Sun and Apollo, but they made some bad business decisions. Lexidata had the patent for the h/w implementation of Z-buffering and should have 'owned' the solids modeling market. The monitor (from memory) should have 2 sets of R G B Vs Hs, which accounts for the 10 bnc connectors. Internally it could probably take sync from the green bnc. It is almost certainly 1280x1024 and might be non-interlaced as Lexidat was either the first or one of the very first to have 1280x1024x60 controllers. Thanks for the memories and I hope this is useful Charles Richmond Manager of Kernel Development -- *********************************************************************** * Charles Richmond @ Sitara Networks * * cmr(a)sitaranetworks.com cmr(a)iisc.com cmr(a)acm.org * * 52 Second Avenue Suite 200, Waltham, MA 02451 * * (781) 487 5919 FAX (781) 684 8291 Cellular (617) 504 3379 * ***********************************************************************
