More on this type of keyboard...
The Model M2 was one of two lightweight alternatives to the Enhanced Keyboard released as the first of the numbered Model M variants. Whilst M2s fundamentally mostly used the same buckling springs switches, almost everything else about the design was changed as they have no metal backplate, an integrated front cover and barrel plate, and a completely different logic board featuring surface-mounted components. The M2 was bundled with IBM Personal System/1 family low-end computers, which contrasts its otherwise identical Model M1 siblings that were sold exclusively as standalone products. Unlike the M1, however, a Quiet Touch rubber dome variant of the M2 was made. Despite being known as the Selectric Touch keyboard, these have no relation to the IBM Selectric typewriter family.
