|Ijack is correct; you'd have to have an IDE disk (and a IDE cable on your new machine) for that to possibly work. If you find you do have the correct interface, you may be able to read it---but there's still a couple things you need to consider:|
1. The disk geometry (Cylinders,Heads,Sectors/Track) may not be read exactly the same as in the Compaq machine. This would possibly cause files to be misread and even possibly corrupt some already on the drive if you try to write to it.
2. Even if the geometry was correct, you won't be able to run DOS/Win3.1 unless you make it the "bootable" drive by disconnecting the primary, or possibly hacking around with the WinVista boot.ini files (as if there were two OS's installed).
If there's something there you want to salvage, you may be better off leaving it in the Compaq and trying to backup to floppies (not very fun) or to something like an external (parallel port) Zip drive. Or remove the drive and connect it to a USB adapter such as:
"Channeling the spirit of jboy..."
