The IBM 4613 SurePOS 100 Express System was a compact all-in-one POS terminal introduced in 2008 that featured an integrated IBM buckling rubber sleeves based keyboard assembly. The keyboard itself resembles a shortened IBM Model M11 and in fact takes production values from late-era RPOS keyboards and sports an RPOS-style magnetic stripe reader. It has 96 keys in an ortholinear layout with both relegendable and alphanumeric setups known. It is considered to be the latest member of the "Model M-e" pre-Modular (pre-MPOS) series.
