Is there some device available which could be easily carried around with a laptop PC, and attached to the external monitor port to be used in conjunction with either an overhead projector or a slide projector for projection onto a screen? -- +------------------------------------------------------------+ | Peter Marks, MCC, 9390 Research Blvd., Austin TX 78759 | | (512)338-3349 marks@mcc.com | | {gatech,harvard,pyramid,seismo}!ut-sally!im4u!milano!marks | +------------------------------------------------------------+

Very small, compact, and easy to use. Cost, including carrying case is a little less than $1300. Contact: Sayett Technology A Division of Eastman Technology, Inc. 1133 Mt.

I recently heard of an LCD device which sits atop an overhead projector in place of a transparency, but that's all I know. Who makes it, what interfaces are provided and how well it works are unknown to me. -- Robert Reed, Tektronix CAE Systems Division, bobr@zeus.TEK

In Focus, Inc. 1618 SW Fist Ave #316 (503)226-4502 I make no warranty nor do I imply any suitability of the device for your intended use. I saw it at Comdex and it worked. It is a flat LCD that attaches somehow to the PC and lies on an overhead projector. The screen image is impressed onto the LCD and projected onto the screen. It is monochrome only. I do not know the resolution of the device. -- John Cornelius (...!sdcsvax!piaget!jc)

The system's cabling provides a 'Y' connection to the output of a CGA type card, allowing your monitor to run at the same time, and a serial port connector for use with the supplied software. The software, called SHOWMAKER, is intended to facilitate the production of slide shows and help organize screen images. The remote control sends setup and control commands to the tablet and can also be used in conjunction with SHOWMAKER. We've been looking for an inexpensive alternative to the SONY or other video projection systems, which run $5K and up. The DATASHOW system is less than $1300 list. Screen resolution is 640 X 200 and the aspect ratio matches the IBM (1.3:1), so your circles come out as circles. The active area of the screen is about 6 X 8 inches, and the overall dimensions are 11.8 X 13 X 2.1". The display image is pretty good, with contrast, brightness, and centering adjustable with the remote. The image can also be inverted to give light on dark or dark on light displays. The nicest thing about it, versus the projectors, is that you can get a nice bright image that doesn't require a high gain screen or a pitch dark room. If you look closely, though there is some flickering of some of the pixels, but at distance the effect is not very noticeable.
