386s are dumpster finds. My bet is it's Windows For Workgroups, which was a nice version of Windows 3.1
If it is a 386, it's just a curiosity and nothing more.
Acquired a cast off Dell that was on a network somewhere. Processor shows up as x386. Doesn't have blazing speed. Ram expressed as 250,000+ kb. Runs win2000 for networks, service pack 4. Has a bunch of Adobe editing stuff installed. If I fill up the Ram with as much as I can find do you think it will make a good backup?
