[comp.sys.ibm.ps2.hardware] PS/2 Mouse Port & Logitech

km4c+@andrew.cmu.edu (Ke-Wei Ma) (04/26/91)

I have this Logitech 2 button mouse for longest time plugged into my
serial port.  Does anybody out there in net land know if it is possible
to connect this rodent to my PS/2 mouse port on my Model 30 so I can
free up a COM port?  Is there a adapter I can buy or does anybody know
how to the pin configurations so I can hardwire an adapter myself?
Thanks in advance.

   Take a close look at how Logitech describes that mouse (on its box or its
   manual).  Some are just called "serial", some are called "serial or PS/2".  
   If it's PS/2, it should be able to plug into the mouse port.  I have one
   plugged into the model 80 I'm using now, with PC-NFS telnet.

   But NOTE: the model 80 is microchannel, the model 30 is ISA.  I have no
   idea whether the same mouse can go on the model 30's mouse port.

   Also, there are certain points where using Logitech's driver for that mouse
   makes the 80 miserably slow.  Notably when I am using Norton Commander, 
   and the commander wants to read the directories to be shown in the
   directory windows, it just sits there for a moment before it displays
   anything.  And this always starts immediately after I run Logitech's 
   MOUSE.COM .

   So now I use Microsoft's MOUSE instead, and it doesn't seem to have any
   problem.

This could help...

This past summer I worked for General Electric on a project that required
PC's and we used Logitech mice with 'em. These mice came in a box that had
a blue label on it stating "serial or PS/2 mouse." These guys were PS/2
port mice that came with an adapter so they could be plugged into a 25/9
pin serial port.  I bought my Logitech mouse within weeks of when I saw
their's because I have a PS/2 mod30-8086(mouse port) and was planning to
upgrade to a new 'puter that would not necessarily(spelled wrong?probably)
have that port.  I looked and looked and... and never found a Logitech
package that had both connections in it, so I bought the PS/2 version. 
	The mouse I had previously was a serial 25-pin mouse and with
pinouts for the mouse and the port(which I got from a friend and have since
lost) I attempted to make the transformation. I DID NOT succede, though I
did blow UP the 2 input IC's that were in my computer! So I saw results! 
But I never tried that again. 
	My advice is to give Logitech a ring or mail saying you need the
patch cable...
	
	I would like to know, from the original poster, is if you have a 
mod30-8086? If so, have you tried using Jack Nickalus Golf and encountered
a floating mouse all over the screen and "supposed button clicks" when
trying to use the mouse in it?

Not a concern.
