오늘로부터 45년 전인 1981년 8월 12일, 컴퓨팅의 판도는 영원히 변했습니다. IBM은 사무실과 가정 모두에서 x86 아키텍처의 인기를 촉발한 계기가 된 '개인용 컴퓨터(Personal Computer)'를 출시했습니다. 물론 이것이 IBM 단독으로 이룬 업적은 아니었습니다. 장기적으로 해당 생태계가 두드러지게 유지될 수 있었던 것은 IBM 호환 '클론(Clone)' 시장의 역할이 컸기 때문입니다. 하지만 그 성공의 큰 부분은 단연 '키보드'에 있다고 저는 생각합니다. 대부분이 동의하듯 완벽한 배열은 아니었지만, 분명 유능하고 견고하게 제작된 키보드, 바로 '모델 F/XT(Model F/XT)'였습니다. 따라서 이를 기념하기 위해 'Admiral Shark's Keyboards'만의 가장 적절한 방식으로 이 키보드가 어디서 왔고 어떻게 발전했는지 살펴볼 것입니다. 물론 IBM PC 탄생의 배경과 그 이면에 있었던 인물 및 사건에 대한 문맥도 필요에 따라 함께 다룰 것입니다.

탄생을 향한 과정 (In the run up)
PC가 등장하기 전, IBM은 개인용 컴퓨터와 인접한 제품들을 출시했으며 1970년대 내내 개인용 컴퓨터라는 개념을 모색했습니다. PC의 모델 번호인 5150은 5100 휴대용 컴퓨터(5100 Portable Computer), 그리고 5110 및 5120 컴퓨팅 시스템의 계보에 속합니다. 5100은 다시 1973년 IBM 팔로알토 과학 센터에서 개발된 SCAMP(Special Computer APL Machine Portable)라는 프로토타입 컴퓨터의 진화형입니다. [4] 당시 IBM 범용 시스템 부서(GSD)의 임원이었던 윌리엄 C. 로우(William C. Lowe)는 이 프로토타입을 구상하는 데 결정적인 역할을 한 것으로 평가받습니다. 5100은 일부 언론에 의해 '개인용 컴퓨터'로 불렸으나, 매우 비싼 가격 덕분에 많은 사람이 접근할 수 없었습니다. 하지만 (1975년 기준으로는) 휴대용이라는 점이 주목할 만했으며, 당시 IBM의 역대 최소 컴퓨팅 시스템으로 강조되었습니다. [5]
현재 IBM의 베테랑 디자이너인 토미 R. 하디(Tommy R. Hardy)는 1976년의 '옐로우 버드(Yellow Bird)'와 1977년의 '아쿠아리우스(Aquarius)'를 포함하여 개인용 컴퓨터를 위한 몇 가지 과도기적인 아이디어를 구상했습니다. 두 디자인 모두 후대의 코모도어 VIC-20, 코모도어 64 등과 비슷한 쐐기 형태였지만 크기는 더 컸습니다. 아쿠아리우스는 양산 직전 프로토타입 단계까지 갔으나, 자기 버블 메모리(Bubble Memory) 모듈의 사용에 대한 자신감 부족으로 결국 무산되었습니다. 1979년 아타리(Atari)가 8비트 컴퓨터를 출시했을 때, IBM은 아타리를 인수하고 800 모델을 PC의 기반으로 활용하는 방안도 고려했습니다. 하디는 이를 위해 진주색을 띠는 IBM 브랜드의 아타리 800을 개념화하기도 했으나, [6] 이 아이디어는 더 이상 진전되지 않았습니다.
하지만 다음으로 주목해야 할 중요한 이정표는 바로 데이터마스터(Datamaster)입니다.
데이터마스터 (Datamaster)
데이터마스터의 도움 없이는 PC와 그 키보드에 대한 논의가 불가능합니다. 'IBM System/23 데이터마스터'는 IBM에게 큰 영향을 미친 경험으로, 이후 PC와 해당 키보드를 개발하는 데 밑거름이 되었습니다. 원래의 '데스크톱(올인원)' 형태인 5322 모델은 1981년 7월에 출시되었습니다. 이어서 1982년 5월 18일에 발표된 5324 '플로어탑(타워)' 형태의 데이터마스터가 뒤를 이었습니다. [10] 이들은 BASIC으로 작성된 비즈니스 애플리케이션을 구동하기 위해 설계된 인텔 8085 기반의 마이크로컴퓨터였습니다. 데이터마스터의 개발은 1978년 2월에 시작되어 1980년 7월에 하드웨어가 완성되었습니다. 그러나 데이터마스터 작업에 참여했던 IBM 엔지니어 데이비드 J. 브래들리(David J. Bradley)의 회상에 따르면, 해당 기기의 출시는...

Reading Time: ~18-22 minutes 45 years ago today, on 12 th August 1981, the computing landscape changed forever. IBM launched the Personal Computer, the vessel that kickstarted x86's popularity in computing at offices and homes alike. It was, of course, not a feat IBM achieved by itself - the IBM-compatible "clone" market is what helped keep the ecosystem prominent in the long run. But I like to think a big part of its success was its keyboard. Not the perfect layout as most may agree, but certainly a competent, well-built keyboard - the Model F/XT. Thus to celebrate, in the most appropriate way for Admiral Shark's Keyboards, we will look at this keyboard, where it came from, and what it became. Of course, with context as needed, including what led to the IBM PC, and both who and what was behind it. Contents In the run up Datamaster Personal Computer 5291 & 5292 Portable Personal Computer System 9000 TPC and EMR Acknowledge​ments Further reading & resources Sources In the run up Before the PC, IBM released products adjacent to a personal computer, and toyed with the idea of a personal computer throughout the 1970s. The PC's type number, 5150, places it in the lineage of the 5100 Portable Computer, and the 5110 and 5120 Computing Systems. 5100 in turn is an evolution of a prototype computer known as SCAMP (Special Computer APL Machine Portable), which was developed at the IBM Palo Alto Scientific Center in 1973. [4] William C. Lowe, an executive in the IBM General Systems Division (GSD) at the time, was considered instrumental in foresting this prototype. The 5100 was touted as a "personal computer" by some in the media, but it was a very expensive and not accessible to many people. It was notable for being portable though (for 1975), emphasised as IBM's smallest computing system to date at that point. [5] Tommy R. Hardy, a now-veteran IBM designer, conceptualised some interim ideas for a personal computer, including the "Yellow Bird" in 1976 and the "Aquarius" in 1977, both vaguely wedge-shaped in a form factor not unlike the later Commodore VIC-20, 64, etc., albeit bigger. Aquarius even made it to a pre-production prototype, but ultimately dismissed due to lack of confidence in its use of bubble memory modules. When Atari's 8-bit computers launched in 1979, IBM also considered aquiring Atari and utilising the 800 as a basis for the PC. Hardy also conceputalised a pearl-white, IBM-branded 800 to this end, [6] but this idea proceeded no further. The next big thing, though, is Datamaster. Datamaster It would be impossible to have a discussion about the PC and its keyboard without talking about the IBM System/23 Datamaster, an influential experience for IBM that aided them in the PC's development and its keyboard. The 5322, the original "desktop" (all-in-one) Datamaster, was released in July 1981. It was followed by the 5324 "floortop" (tower) Datamaster, announced on 18 th May 1982. [10] They were Intel 8085-based microcomputers intended to run business applications written in BASIC. The development for Datamaster began in February 1978, and its hardware was ready by July 1980. However, as recalled by IBM engineer David J. Bradley, who worked on Datamaster, its launch was delayed by a year and to just a month before PC thanks to IBM deciding to develop the Datamaster's BASIC more in line with the IBM System/34 midrange computer's implementation of it. [11] The 5322's styling is attributed to Tommy R. Hardy via its U.S. design patent ( 275,285 ), which was filed on 4 th February 1980. The design at that stage was largely like the finished product, though the keyboard layout is slightly different, with extra keys and a non-stepped Enter key. If design patents for 5324 exist, I was not able to find them during my research. The Datamaster keyboard establishes the basis for every other keyboard discussed today. It is presently the earliest confirmed Model F keyboard implementation to make it to market, which would soon expand into an entire family of IBM flagship keyboards prominent for the first half of the '80s. They all use capacitive buckling springs , a keyswitch design by Richard Hunter Haris ( U.S. utility patent 4,118,611 ), where pressing a key compresses a metal coil spring underneath in a way that it eventually "catastophically" buckles, which in turn pivots a small plate made of a capacitive material atop a capacitance-sensing PCB called a "pad card". The 5322 keyboard is a complete sub-assembly (CSA) that sits inside the host Datamaster. The keys are arranged in a layout derived from the Model B-based IBM 5251/5252 Display Station Typewriter Keyboard , which was IBM's most immediate and common pre-Datamaster keyboard design. The aforementioned pad card bears a 12x8 key matrix and an Intel 8048 as its controller. The keyboard uses a parallel-style interface where an inverted 7-bit scancode is sent across separate scanbit lines at once and together. Like its layout, its scancodes are also derived from the 5250 family . On the receiving end, according to RetroAND (bitspassats.com), the Datamaster has an 8255 Programmable Peripheral Interface configured for mode 1 input. As the keyboard is completely internalised, it connects directly to the 5322 motherboard (CPU planar board) via an 8x2 header. As the 5324 is a distributed system, its version of the keyboard is discrete, connecting to its host via a DB-25-terminating cable. Chronologically, this was released after the PC, so it derives its styling from the PC's keyboard, but with a considerably enlarged cover set and slightly longer riser feet . It may sometimes be confused with the IBM 5291/5292 keyboard also discussed later, but the 5324 keyboard has the largest bezel between them, to the point it sometimes gets nicked the "bezelmaster" Model F keyboard. The 5324 keyboard reuses the 5322's keyboard CSAs. But the 5324 keyboard adds a "keyboard adapter card" before its external cable. As explained to me by RetroAND, it has positive buffers and double negations for the control signals, likely to reduce noise. In effect, it prepares a design that was originally integrated into something, to be a distributed design that requires a longer cable. Personal Computer Roll back the clock to July 1980: Lowe - who was involved with SCAMP - pitched the idea of a small, low-cost business and consumer computer to IBM CEO Frank Cary, who subsequently gave him a month to develop a prototype and to launch the finished product in a year. It was dubbed "Project Chess". Lowe was promoted soon after, so Chess fell to Philip Donald (Don) Estridge. [17] [18] The team consisted of about twelve engineers, who were famously able to develop the PC outside of IBM's typical processes, ultimately allowing them to meet the one-year deadline, rather than complete it in 2 to 5 years like most other IBM systems of the time. The earliest sketches of what became the PC, from 10 th August 1980, were only relatively recently published. They show that a lot of what became the PC were nailed early on, including its use of the Intel 8088, five expansion slots, two floppy diskette drives, use of ASCII instead of EBCDIC, and a detached Model F-based keyboard. There are some notabl
