InPort
Microsoft InPort is a deprecated pointing-device port interface for the IBM PC. The port has a 9-pin mini-DIN connector, same size as the later PS/2 mouse port but with different physical pins.
InPort is a type of bus mouse interface of which there are several types with different connectors. Microsoft's particular bus mouse interface got adopted by other manufacturers and thus the term "bus mouse" in a PC context more often refers to this particular type of port.
Mice often came bundled with an ISA interface card to be installed inside the PC. Rumour has it that the chip on Microsoft's InPort card could be reconfigured for other types of peripherals, but no product other than mouse is known. The port was contemporary with the use of the serial mice and both got deprecated after IBM had introduced the PS/2 interface.
Adaptors
- An adaptor from InPort to DB-25 serial port was bundled with some variants of the "Dove bar" Microsoft Mouse.
