eg, P/N 1440401

54-key integrated keyboard assembly with On/Off rocker switch for IBM Electronic Typewriters models 50, 60 and 75, IBM's first typewriters that were electronic rather than [electro]mechanical (ie, able to perform some amount of internal processing via electronics than rely on mechanical elements). The keyboard assembly seems inspired by IBM Card Punch keyboards but uses a series of magnetic reed sensors for key-stroke sensing. The keys can lock, which requires the host typewriter to unlock them.

eg, P/N 7363831

IBM-made 84-key typewriter-style keyboard for the IBM 5253 Display Station and 5254 Dual Display Station (both terminals for the IBM 5520 Administrative System). They were intended for facilitating document creation and editing, and management of their storage. They could also support an IBM 3270 emulation mode. This variant is the 96-character keyboard with a 1.25-unit left shift key and an "ISO-style" return key. They had a 32Ω, 0.2W speaker inside though its purpose is presently unclear. The keyboard itself and its layout became the basis of the slightly later IBM Displaywriter Keyboard.

IBM 5253/5254 Display Station Electronic Keyboard

525X-82 type Model B, 92-character variant

eg, P/N 7363830

IBM-made 82-key typewriter-style keyboard for the IBM 5253 Display Station and 5254 Dual Display Station (both terminals for the IBM 5520 Administrative System). They were intended for facilitating document creation and editing, and management of their storage. They could also support an IBM 3270 emulation mode. This variant is the 92-character keyboard with an ANSI-like 2.25-unit left shift key and a "BAE" (large backwards-L) style return key. They had a 32Ω, 0.2W speaker inside though its purpose is presently unclear. The keyboard itself and its layout became the basis of the slightly later IBM Displaywriter Keyboard.

IBM 5281/5282/5285/5286 Data Station Typewriter Keyboard

IBM-made 83-key integrated keyboard assembly for the IBM System/23 Datamaster (IBM 5322 "desk-top" variant). This keyboard assembly is presently the earliest confirmed Model F keyboard design and buckling spring keyboard at large. The layout is derived from that of the IBM 5251/5252 Typewriter Keyboard but makes minor tweaks to establish the true XT-style physical layout.

IBM Personal Computer Keyboard

aka "Model F/XT"

eg, P/Ns 1501100, 1501101, 1501102, 1501104, 1501105, 1801449

IBM-made 83-key keyboard for the IBM 5150 Personal Computer and 5160 Personal Computer XT. It's famous for being the original IBM PC keyboard and is also the earliest known discrete Model F keyboard (ie, not integrated into a larger system) and introduced the XT-style functional layout. It has a black, coiled cable terminating in a 5-pin DIN plug, single-setting riser feet accessible from the sides, and 4 cork feet to prevent sliding. Two variants exist; a Type 1 keyboard with a metal-jacketed DIN plug that supports a RESET line and a Type 2 keyboard with a plastic-jacketed DIN plug that doesn't.

IBM Electronic Typewriter 65/85/95 Keyboard Assembly

eg, P/Ns 1305676, 1305677, 1305679, 1305687, 1415880, 1437057

54-key integrated keyboard assembly with On/Off rocker switch for the IBM Electronic Typewriter models 65, 85 and 95, the second generation of IBM's first typewriters that were electronic rather than [electro]mechanical (ie, able to perform some amount of internal processing via electronics than rely on mechanical elements). Compared to their model 50/60/75 predecessors, the keyboard assembly is a lot thinner thanks to being based on Model F capacitive buckling spring technology and its keys can no longer lock themselves. Despite being Model F based, these keyboard assemblies unusually have melted plastic rivets like a Model M based keyboard assembly.

IBM 5324 System/23 Datamaster Floortop Keyboard Module

eg, P/Ns 8257796, 8529401, 8529404, 8529412, 8529416, 8529418, 8529420, 8529422, 8529424, 8529428

IBM-made 83-key discrete keyboard for the IBM System/23 Datamaster (IBM 5324 "floor-top" variant). This version of the Datamaster and this keyboard were announced later than its 5322 integrated counterparts. The keyboard resembles the slightly earlier IBM 5291/5292 Display Station Keyboard with its large bezels (compared to the IBM Personal Computer Keyboard) but is larger still and only has one adjustable riser feet size. The layout is derived from that of the IBM 5251/5252 Typewriter Keyboard but makes minor tweaks to establish the true XT-style physical layout.

IBM 5291/5292 Display Station Keyboard

529X type Model F

eg, P/Ns 1397950, 4176191, 5642852, 5643009, 5643010, 5643011, 5643012, 5643014, 5643024, 7363290

IBM or Lexmark made 83-key typewriter-style keyboard for the IBM 5291 Display Station and IBM 5292 Color Display Station, both IBM 5250-compatible terminals. The keyboard resembles the IBM 5150/5160 Personal Computer Keyboard but with enlarged bezels and its characteristic three-setting riser-style feet. This earned it the community nickname "bigfoot" Model F. The keyboard also lacks its own controller and thus doesn't produce its own scancodes (the electronics inside only allow for capacitance sensing for the host terminal to control itself). The keyboard was available in two variants that were identical apart from the cable; a Type 1 keyboard for IBM 5291 Model 1s with an integrated connection via a 14-pin IDC-style connector and a Type 2 keyboard for 5291 Model 2s with an external connection via a DA-15 plug.

IBM 8775 Display Terminal 87-key EBCDIC Typewriter/Text Entry and Edit Keyboard

327X-87 type Model B, feature no. 4670

eg, P/N 5147351

IBM-made 87-key typewriter-like keyboard for the IBM 8775 Display Terminal (a terminal for the IBM 8100 Information System that supported IBM 3270 datastreams over serial instead of coax). This feature number 4670 keyboard was introduced late for a Model B keyboard variant and was intended for IBM 8775s running Interactive Display Text Facility (IDTF, a licensed program that enabled the host terminal to be used in both data and text applications). On top of the base IBM Base Keyboard/3270 typewriter-style layout, this keyboard had various application-specific green front-printed legends and special numeric keypad keycaps designed to hold a reversible overlay card in place. On one side of this overlay card were the standard program-function key assignments, and on the other were functions that apply when the 8775 is used with the IDTF program. Typical for a 327X-87 type Model B is the keyboard's internal clicker assembly and palm-rest compartment for documentation.

IBM System 9001 Standard Keyboard

aka IBM Instruments Computer System 9000 Keyboard

eg, P/N 4780898

IBM-made 83-key keyboard for the original IBM Instruments Computer System 9000 laboratory computer model (later known as the IBM System 9001 Bench-Top Computer). It's a variant of the IBM Personal Computer Keyboard that lacks any sort of adjustable feet and has its cable sprouting from the keyboard's lefthand side instead of its rear. It has a black, coiled cable terminating in a 5-pin DIN plug and 4 cork feet to prevent sliding. The "Standard" in the keyboard's name contrasts it with the later IBM System 9002 Hybrid Keyboard.

IBM 6580 Displaywriter Display Station Type B Keyboard

630X type Model F, 96-character variant
