Review of The Logitech High Resolution Mouse
                       Copyright 1989 by David Batterson


     The new Logitech high resolution--320 dots per inch (dpi)--mouse is a
welcome improvement over the C7 model I reviewed last year.
     The serial version (bus version also available) is compatible with all
PCs, so is the preferable one to get in my opinion.  You may have a modem
plugged into your serial port, so unless you have a second serial port, you'll
need a switcher box to make use of both.
     The mouse works with all applications, such as Publisher's Paintbrush,
IMSI Publisher, Dr. Halo III and DesignCAD.  It comes with a new MouseWare
Utilities disk, Ver. 4.0, completely revamped.  Included is "Mouse-2-3," the
shell for use with Lotus 1-2-3.  It also has the new Pop-Up DOS (DOS shell),
plus 35 ready-made menu definition files (.DEF) for such applications as
Framework III, Symphony, VP-Planner, WordPerfect 5.0, and XTREE PRO.
     For software not written for mouse usage, the manual provides good
instructions to help you write a simple program which will make it work.
     The best change from the older Logitech mouse is the higher hardware
resolution.  This means it takes up much less desk space (62% they say), as the
cursor movement needs only a flick of the wrist now.  If you are like me, and
have limited free desk area, this is an important advance.
     Mouse resolution can be adjusted widely, according to your preference and
the type of software application, i.e., you can vary it for precision or speed.
     The mouse also has a better shape and feel to it.  It's curved to fit the
palm of your hand, and the three buttons are at the extreme top.  You get
accustomed to using it immediately.
     Since it uses opto-mechanical technology, you do not need a mouse pad (as
you do with optical mice).
     An option with the mouse is PaintShow Plus, a graphics program similar to
PC Paint and PC Paintbrush.  It's not particularly better or worse than its
competitors, so nothing to get excited about.
     Naturally you're going to pay a higher price for this high-res mouse. 
Suggested list is $139.00--but nobody pays list prices.  Check the major mail
order ads (such as in Computer Shopper magazine) for best price.
