Hi gang - [This isn't *directly* VAX-related, but it seems to be the appropriate list.] The University is in the process of revamping a lecture hall and wants to put in all the latest and greatest electronic teaching tools, which of course means (among other things) --> video projection. They'd also like to have their cake and eat it too, that is, have one projection system suffice for 'regular' video projection (e.g. VCR) *and* for output from a computer terminal (VT200-series) or PC (IBM PC+compatible, also DEC Rainbow if possible). They would also like to be able to buy the cheaper (oops, "more economical") model which has more limited options and capabilities. Our audiovisual technician is getting rather frustrated as nobody seems to really know (a) whether this is possible and (b) if it is, what are the specs? He was talking about scan speeds and the like, but it's really beyond me. Our own department is using two LimeLight projectors (from Vivid Systems Incorporated, Fremont, CA) but those only work with VDT equipment. So - if you or the entity with which you are affiliated has had any experience in this arena, any information/experiences/guidelines/horror stories/etc. you have would be greatly appreciated. Please send to me and I will summarize to the net if there is enough interest. aTdHvAaNnKcSe, % Denis W.

(or TI explorer) They are much less tempermental than the GE oil film monster, tho they do have a fiddly adjustment or two. (mostly having to do with the bias voltage on the LCD "hockey puck", said adjustment controlling the contrast. the knob for this is on the back, and it is not hard to do, I have one it over the phone on more than one occasion.) There is rumored to be a color version of the thing, but I have never seen one. (there are also armor plated versions, the thing was originally developed for NORAD.) If your AV type has further questions, have him give me a call (617) 661-7171 (usual hackers hours) <dp>
