The Model M Keyboard
How can you tell a Model M keyboard?
Well, frontside will look something like this...
...you can count 101 keys, and no more.
Bad ass model m keyboards come with "quick connect" ports on the rear for plug and chug portability.
do so note that the absence of this feature does not rule it out as being a Model M. Later Models, when Lexmark ruined the design, lacked this design but still click and clack in the same "force feedback" mindset of its earlier prototypes.
yep, every Model M keyboard comes with one of these...
I would like to regard it as a birth certificate for the keyboard itself:
note the birthplace.
and most importantly, if you modelm sounds like this, its definetely an 'M'.
