More on this type of keyboard...
The IBM 6580 Displaywriter System was a diskette-based word processing system that was originally released in June 1980 with a Model B-based keyboard. In November 1982, IBM announced this optional low-profile alternative designated the "Type B" keyboard with the original keyboard retroactively designated "Type A". The Model F-based Type B keyboard is plug-compatible with the original keyboard but is far thinner and is capable of being adjusted for 5-degree and 12-degree typing angles which IBM then touted as being "ergonomically designed". The Type B keyboard features the same functional layout as the 96-character Type A keyboard. In a way, the keyboard's alphanumeric section provides an early glimpse into what would become the ISO layout with 1985's IBM Enhanced Keyboard, making the Type B one of the most modern-looking early Model F keyboards.
