Converged Keyboard
Provided by the ASK Keyboard Dictionary
"Converged Keyboard" was IBM's official name for a 104-key, 122-key or similar keyboard with a two-row 24-key function key area, a plus-shaped arrow key cluster and a left-side two-column 10-key area. The concept was introduced in 1983 with the IBM 3290 Information Panel's 104-key Model F keyboard. IBM Model F and Model M keyboards understood to be "unsaver", "battleship" or "battlecruiser" style by the keyboard enthusiast community are all a part of the IBM Converged Keyboard lineage.
