+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+A type of mechanical keyboard originally made by IBM for the early generation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.
