Transview 480                    data screen, IBM XT/Macintosh
Project Your Computer Screen on an OHP
 
If you have been involved in making presentations, you are
familiar with the problems that can arise with overhead
transparencies -- they can be dirty, damaged, incorrect, or
missing altogether. But now Davis's Transview 480 data screen
lets you prepare the images in advance using a personal computer,
and then display them in large format on the computer screen and
an overhead projector simultaneously.
 
You connect Transview to the RGB output of your computer and
place it on top of an overhead projector. The unit automatically
detects the output format from the computer, performs screen
setup, and optimizes the screen picture for any given computer or
software. You can also key in additional information during the
presentation and project it simultaneously.
 
The Transview 480 has a 640- by 480-pixel high-contrast,
double-supertwist, black-and-white display that lets you choose
from 384 color combinations with eight shades of gray and six
hatching patterns. You simply press Auto on the remote control,
and an internal microprocessor analyzes the incoming RGB signal
for the number of horizontal lines, the number of dots per
horizontal line, and the horizontal and vertical position of the
image. Then Transview 480 adjusts itself.
 
The remote control also lets you override all automatic
functions, including hold, clear, inverse video, and contrast
adjustment. You can use Transview 480 with most personal
computers -- including the IBM XT and AT, IBM PS/2s, and the
Mac -- that have normal analog or digital TTL RGB output and
dot clocks in the range of 14 to 30 MHz. The unit measures 376
by 291 by 43 mm.
 
Price: 17,000 Norwegian krones.
