This is for the 40mb PCMCIA card made by M-Systems (made in Israel). These drivers were sent to me by the manufacturer (only place I could get them!). I requested Win9x drivers, but have only used these under Win98 SE, so haven't verified the other O.S.'s. The company no longer supports these, but I kind rep sent them to me, anyway (thanks, Mr. Hutzler!). These are zipped.
