I found this diskette when I was cleaning off a shelf; it's a 1.2M 5.25" floppy with a bunch of stuff for the IIT numeric coprocessor sold for use in 80386 systems. Maybe it'll have some use. Zippped IMD...
To be quite frank, I'm not sure how fussy the stuff on the disk is. I probably had a system with an IIT copro in it, but I don't now. Since one of the files mentioned the 80386, and given the 1990 date, I'm guessing.
