Thanks Mickey for reposting Jeffs note on connecting MS mouse to ST

HOWEVER, It appears to me that microsoft has changed their mouse cable
the number of lines and the shape of the connecter are very different
from what you described. (I have the latest MS 400 DPI serial-ps/2 mouse,
did I make a mistake? should I have gotten the bus mouse?)

For example pin 5 on the MS mouse isn't connected to anything in mouse
also on my ST mouse I can press the left button and note resistance on my
volt meter go to zero when I make the approriate connections (between pin 6
and 8) I cann't find any equivalent correlation on the MS mouse, (Though
I haven't tryed every possible iteration).  Strangely, resistance does drop
(electricity travels through, me no EE;) through some combinations
of lines but pressing mouse buttons never seems to make any difference.

The MS mouse apears to use only lines 2,3,4,5,7 of an AT (9 pin) serial
connector (and the casing)

Can someone e-mail me the solution to this problem (the correct wiring,
or tell me I goofed and bought the wrong mouse).

by the way I haven't received anything form info-atari16 for about a
week so you better e-mail me directly.
