Look at how much electronics have changed since 1985-ish when the 1A3 was generally still new.

Windows 1.0 was release...how much money would you spend for that OS running on a 386 machine (that was also a new release in 1985)?

I wouldn't expect getting much money selling one, but if you find someone in desperate need of one then it's all timing.
