View Full Version : Search for Olivetti M24: Keyboard mouse driver

January 10th, 2016, 03:52 PM
Hello, for my Olivetti M24 I am searching the special mose driver which allows to use the Keyboard 2/3 attached mouse to be used as a standard mouse from any software. Without that driver, the mouse is already useable, but only to emulate cursor and enter keys. Can someone please point me to that driver?

This should be the driver for the keyboard mouse as both a zip file and 360KB floppy image

Hello, that's it, thanks. I will try it tomorrow.

By the way, this mouse uses the same signals as an ATARI ST or Commodore Amiga mouse. You only would need an adapter because the pin assignment to them is different. So if someone want to test this mouse without having the original one, this is possible. The Olivetti/AT&T keyboard mouse is a very rare thing.

I bought a Tektronix mouse (http://www.ebay.com/itm/Vintage-Tektronix-3-Button-Mouse-for-Terminal-4207-PN-119-1808-00-Serial-Port-/181808228019/) for my M24 and i rewired the cable connector inside the mouse so i dont need an adapter.

On page 27 of the schematics (http://www.olivettim24.hadesnet.org/docs/m24schem.pdf) you can find the keyboard circuit with the pin numbers for the mouse.
So it should be easy to connect a ATARI ST or Commodore Amiga mouse to your Olivetti M24 / AT&T PC6300.

Hello, I just found out that I still have some trouble with the mouse. To double check I also attached a microsoft mouse and a logitech mouse to com1 (not at the same time) and started them with ms-mouse-driver and logi-mouse-driver. Everywhere the same behaviour. Some programs run fine, like checkit mouse tests, others ignore the mouse button click, like Norton Commander and GEM/3. Mouse moving always work with these. Any ideas? (The M24 runs MS-DOS 5.0).
