The Tandy 1000 RL, RLX, and TL/3 systems feature a "PS/2" mouse port that, while protocol-compatible, isn't accessed in standard PS/2 fashion. Given a lack of documentation, it's also something of a mystery.
Support-wise, either CuteMouse or a specific version of Logitech's mouse driver can be used in DOS. Regrettably, Windows 3.0 and 3.1 support for this mouse port is entirely lacking, generally resulting in the use of a serial port/mouse combination instead. Where I'd like to put the single serial port of the RL and RLX to greater use, this is problematic.
Question is, what needs to be modified in Windows' standard mouse driver to provide compatibility?
As concerns the Tandy implementation, and per the RLX service manual:
Where the keyboard/mouse IRQ sharing isn't unheard of, and may even be accounted for in Windows' MOUSE.DRV besides, is the non-standard I/O port the key?

As concerns the Tandy implementation, and per the RLX service manual:
- IRQ 1 is shared by both the keyboard and mouse.
- Port 0060h is used for keyboard I/O, and port 0067h is used for mouse I/O.
