Does anyone know of an emulator for a Tektronix graphics terminal in the 4100 series (we have 40xx in Tektools)? I believe we need the 41xx for grey-level images. (Specifically, I want to run a PR1ME Medusa (CAD) package from a Sun, with grey-level shading). Electronic mail (uucp) address: rogf at ee.surrey.ac.uk
