PSpice 2.06 damaged diskettes 4 and 6

Hello:

Have tried PSpice 2.06 (in MS-DOS), but cannot read the diskette (diskette read error) number 4 (Parts program)

and diskette number 6 (part of User-changeable Models -Device Equations in recent PSpice versions-)

Diskettes 1-2 are PSpice, 3 is Probe, 4 is Parts and 5-7 are User-changeable Models, all diskettes are 5 1/4" 360Kb

IBM format.

Could someone send me  the contents of diskettes 4 and 6?

thanks
