(offers) operating systems
I have collected operating systems for several decades, if any in staff are interested send me a note. I will provide access for them, I'm not sure how much of my stuff you got and there are too much to list here

We are probably good in the typical Mac/Windows/DOS area, unless you have something really early (For example, the 720K IBM OEM of Windows 1.04 is still on the wanted list). But I am sure there are lots on non-PC OSes that need archiving.
