A cheap, yellowed early 2000's keyboard:
The attachment IZITK-105M.jpg is no longer available
Wouldn't normally be worth a second glance, except for...
The attachment Buckling Spring keyboard.jpg is no longer available
...the buckling spring mechanism! Hardly an IBM Model-M, but an interesting curiosity nonetheless. Model number is IZITK-105M, apparently manufactured by the Can Technology Co. Ltd., Taiwan.
It has an unusually small spacebar and a Fn key next to the right shift, which can be used to set the repeat rate. Pressing Fn+Print Screen causes it to output the string "eleen enterprise co., ltd. v1.02" to the connected PC.
