model m
|
||||
|
||||
A type of mechanical keyboard originally made by IBM for the early generation
|
||||
of PCs in the 1980s. These keyboards are known for their novel use of buckling
|
||||
springs rather than microswitches and metal backplate which gives them a
|
||||
distinctive typing sound. The design was sold to a company named Unicomp in
|
||||
the 1990s and these keyboards are still manufactured.
|
||||
|
||||
The model M keyboard (either original or Unicomp versions) are popular with
|
||||
hackers who enjoy the historical connection to early personal computers,
|
||||
the build quality and the ease of key removal and cleaning. Since a
|
||||
hacker's main tool is their keyboard it's worth investing in something
|
||||
durable and ergonomic.
|
||||
|
||||
On some older model M keyboards the plastic rivets holding the metal
|
||||
backplate on become brittle and fall off. These can be replaced using
|
||||
standard tools in a procedure known as a "bolt job". Such repairability
|
||||
is rare for a modern keyboard.
