Until 2 years ago I owned one each of:
- IBM XT mono and colour monitor, no HDD - 2 x 5.25" floppys
- IBM AT
- TPCII (circa 1984) -

- Intel 286, 386 and 486 - all three configured with operating systems, applications, RAM and HHD of their day.
- Apple Lisa and 2 versions of Macintoshs
- 4 Sharp laptops circa late 1980's
All the above were fully operational and in mint condition.
My Shed was a museum to the early home computer age.
I spent a bit of time trying to find an owner who would set up a museum in Melbourne to put them on permanent display. I felt that later generations would find them of interest, and with the growing trend of the disposable society, once technology has been thrown to the tip, it's gone for ever.
Sadly, I couldn't find anyone to take the collection as a whole, so I sold them off individually, recouped some costs and regretted it ever since, but I just did not have the space.
I still have a couple of 7" floppy disks stored away
