Mouse Systems M-1 Mouse

Early customers of the first Mouse Systems mouse, Model M-1, included VisiCorp and Sun Microsystems. They each commissioned OEM mouses with their own brands on the label.

The mouse required a separate power supply. The package includes:

  • Optical mouse
  • Metal reflective grid desk pad
  • RS-232 serial plug on a Northern Technologies 5V power supply with jack on other end
  • Interface block
  • Manual

The mouse calibrates each time it is powered on.

The Mouse Systems Corporation M-l Mouse Technical Reference Manual printed in 1983 introduces the equipment:

This document explains all about the MSC M-l optical mouse. MSC has been shipping the M-l unit since 1982 and this document is constantly updated with feedback from our customers. If you have any questions, comments, or problems, feel free to contact us.

MSC is constantly improving the M-l mouse. Our new M-2 mouse will use almost half as many components as the M-l and many potential problems with the M-l will be non-existent in the M-2. However, new products take time.

The mouse is a fairly simple device. Basically all you do is plug it into your system and go.

When the mouse is first powered up, it goes through a calibration sequence:
MOVE THE MOUSE IN WIDE CIRCLES (E.G., 6 INCH DIAMETER) AT A COMFORTABLE SPEED UNTIL THE CURSOR ON THE SCREEN MOVES. This should only take a few seconds.
