Mouse Systems M-4 Mouse

The M-4 mouse gets its power from the computer without a separate power supply as on the early models. The serial DB-25 plug is still available, as on the OEM mouse for Siemens, but the smaller DE-9 serial plug is becoming more common, as on the PC Mouse.

A reflective gridded mouse pad is required. Unlike the earlier Mouse Systems pads' coarse grid of about two dozen lines per inch, the M-4 uses a mesh several times finer of fine blue ink and infrared ink lines on a silver colored metal pad.

On the back label the MOUSE SYSTEMS brand appears in block italic font with the two triangular stylized mouses in outline and solid.

Mouse Systems continued to produce mice for other companies. The corporation made an OEM Model M-4 mouse for Quadram which had only two square buttons. The OEM M-4 mouse for Sun Microsystems used its modified RJ11 plug.
