Old operating systems/Computer programs
I recently started this one so it's still pretty small.
For now i own an sealed copy of windows 7 professional (forgot where it is so no photos for now), a copy of windows 95 update and a Powerpoint for Windows 95 (sorry for bad photo quality, my phone camera sucks)
I also have lots of old commercials for the windows 95, ibm pcs and compaq armadas, but it would take up too much space if i put them here, i may put them on youtube one day, as i doubt some of them are publicly available on the web.
I also recently bought on the web an windows 98 copy, but i haven't received it yet.
