Under the Hardware help notes in Flex, for the 2500 XL it states that the

mouse port is a DB-9 connector. It is actually a PS-2 connector and has

6 pins. Please note below the PS-2 connector. It would be appreciated if

this information could be posted under the Help Notes for the 2500 XL.

MOUSE AND LOGITECH DRIVERS

The MOUSE.SYS and MOUSE.COM that is now included with MS-DOS versions 3.3

in the 2500XL, 2500XL2, and all newer 4000's is a Logitech Mouse Driver. When

loaded, DOS will present a Logitech Mouse Driver Screen, not a MicroSoft Mouse

driver screen.

This driver will work fine with the 25-1040A, 25-1040B, and 25-1040C Tandy

Serial Mouses. it will not work properly with thee original 25-1040 Tandy

Serial Mouse, they must get the MOUSE.COM and MOUSE.SYS files from 25-4109

MS-DOS.

If you have the customer turn over the mouse, the catalog number is on the

bottom of the mouse on the identification plate.
