Plz i have been doing this since 3 months and still am not able to crack the problem
I thought I remembered wrong, cause I could not visualize that anyone were working with the discontinued/abandoned machines and - especially not trying to interface to a mouse that probably is not made any more. However googling to find out I found the following:
http://panda.cs.ndsu.nodak.edu/%7Eachapw...S2/ps2.htm

which lead to the question: "why did you not google 3 months ago?"

BTW: Philips has an appnote with '51 code for the AT keyboard and the above states that the PS/2 mouse protocol is the same.
