|What we're working on...|
I have a couple of the memory cards shown in the first link, but (far as I remember) they're only 4Mb or 8Mb and untested.
The following is from a 2140 user manual...
"Use the PS/2 mouse/ keyboard port on the computer.
Make sure the mouse has a cable with a 6-pin connector for the PS/2 mouse port. If the mouse's cable is not compatible, see your dealer for an adaptor cable.
How the computer treats the connection to a PS/2 mouse depends on the setting for Pointing Devices under the HW Setup or TSETUP program. If Simultaneous is selected, you can operate both the MousePoint and the PS/2 mouse. If Auto Selected is chosen, the MousePoint is disabled when a PS/2 mouse is connected.
To connect a PS/2 mouse:
1. Turn the computer off.
2. Connect the PS/2 mouse to the PS/2 mouse/ keyboard port on the computer, pressing gently to assure a firm connection.
3. Turn on the computer.
To disconnect the mouse, turn off the computer and pull out the mouse connector.
Consult your mouse manual for instructions on how to install necessary software.
