Description

The Raytheon 6104-04 keyboard was part of the Raytheon Display Terminal System family;

Two typewriter-style keyboards (both ASCII), one without and one with a numeric keyset, are available with the 2260 Emulator. A 69-key data entry and a 69- or 81-key typewriter keyboard are available with the 3270 Emulator. EBCDIC-only keyboards are provided with the Local 3270 Emulator; while EBCDIC or ASCII keyboards are available with the Remote 3270 Emulator.

The 69-key format includes 2 Program Attention keys, and the 81-key format adds 12 Program Function keys. Appropriate keyboards are provided with the PARS/IPARS, Honeywell, and Univac emulators. A magnetic stripe reader may be added to the keyboard for security.Keyboards are not connected to their corresponding display monitors; data keyed and data displayed are entirely controlled by the stored program.

The 6104-04 uses ITW magnetic valve switches that employ a magnetism to stop the flow of current which signals a press as opposed to a Hall Effect switch which detects the strength of the magnetic field directly. Unfortunately, ITW keycaps are not compatible with Honeywell Hall Effect switches. This keyboard uses a Deltrol clicker which is not a solenoid. Both electromagnetic Hall Effect and Magnetic Valve contact mechanisms are rated similarly high in durability.
