http://imgur.com/a/efXtCPicked this up at a local recycling centre yesterday. Managed to get it for $5, because I just wanted the keycaps. The keycaps are completely unused, no sign of wear at all.
I couldn't find any information about this Simplex company on Deskthority.
I did some research, and it turns out this Simplex company makes fire monitoring systems (those locked fire system panels you see in the entrance of large buildings). Looks like some of their larger systems sit in server racks, and have re-branded Cherry keyboards in them.
Probably explains why the keycaps have no wear, the keyboard is probably never used in these fire systems. Might be something to look out for, if anyone wants some virgin OG Cherry doubleshot keycaps.
