At least S-100 stuff is uncommon enough to be somewhat forgivable.
It is stuff like this that really annoys me:
"UNiSYS Windows for Workgroups 3.5" Floppy Disc Set Of 8 Version 3.11 1994 Rare"
https://www.ebay.com/itm/324784413683
Yea, like this is the last copy of Windows for Workgroups on the planet, and there are thousands of rabid Unisys collectors out there.
"Microsoft Word for Windows 95 on Nine (9) Vintage 3.5" Diskettes - RARE"
https://www.ebay.com/itm/255116714638
Yea, absolute unique one of a kind because it has been installed and serialized.
"Rare Windows Magazine 8 Issues 1998-1999 + Microsoft Mag Ships Worldwide"
https://www.ebay.com/itm/194403545128
Cuz, ya know, like, what's a boooook? (Wait, is toilet paper getting "rare" again?)
"Vintage Microsoft Word For Windows Version 1 on 5 1/4 Floppy Disks ULTRA RARE"
https://www.ebay.com/itm/274963887619
Vintagey and ULTTRAAA RAAARE! From Australia? Perhaps these are some of those disks that spin the other direction.
