Hi there and thanks for looking!
I\'m offering for your consideration a lot of vintage Microsoft Ballpoint Mouse [mice]. The lot includes the following items:

• Microsoft Ballpoint Mouse P/N 31664 - Very good working condition
• Microsoft Ballpoint Mouse P/N 13340 - Parts or repair only
• (2) Serial to PS2 adapter cables
• (2) Clamp mounts w/various adapter jaws
• Original floppy disc with drivers
• Original user guide and license agreement card
• Extra mouse ball
• Extra mouse ball retaining ring

Used these for years until serial ports and PS2 plugs disappeared from computers. It will still [kinda] work with a USB adapter, but really best for computers with the correct plugs. A perfect accessory for your vintage PC build!
I\'ve done my best to capture all relevant details in the attached photos, so please examine them closely and email me with questions before buying or offerding as no returns will be accepted on this lot.
