See more » IBM Model M keyboards keyboard : a hardware device consisting of a number of mechanical buttons (keys) which the user presses to input text or numerical characters into a computer. IBM model M keyboard : a hardware device designed and based on IBM mechanical typewriter design, said by some to be the best example of keyboard design, engineering and construction. Each key has an individual micro-switch which uses a buckling spring mechanism to transform human force into an electrical signal. In 1888, International Business Machines (IBM) was first incorporated. Early on IBM designed and built mechanical "tabulating systems" for accounting and time-keeping. By the 1930’s IBM started to develop and research typewriter technology (IBM model 01 typewriter). Through the 1950s and 1960’s IBM further advanced in their technical expertise in typewriter design (IBM model A, model B, model C typewriters). By 1984, after 50 years of typewriter development, IBM had the expertise and production facilities to develop the first computer keyboard for the IBM Personal Computer (IBM PC). IBM’s design for the 101-key keyboard quickly became the de facto industry standard (IBM model M keyboard),and others imitated and launched the "IBM-compatible" hardware industry. In 2008, most computer keyboards are designed and built outside of the United States. Foreign manufacturers try to introduce new tricks and gimmicks to "improve" the computer keyboard (additional "useless" function keys, odd non-standard layouts, LEDs and neon shiny lights, volume dials and controls, clear polymer casings, smaller keys, narrow key spacing, lightweight typing action, use of silk-screened paint to apply lettering to keys or use stickers which wear over time, and basically producing the lowest cost units that need to be replaced on a 2-3 year cycle). Many computer professionals, prefer to use the one true standard of computer keyboards. Designed by American mechanical engineers, in contrast to new-age designers and focus-group marketing "experts". Many vintage IBM keyboard enthusiasts have purchased one IBM model M keyboard and have been using the same one keyboard for decades. The computer keyboard is among the most under-appreciated components of the computer. In reality, the keyboard is the one part of the computer that gets the most physical contact. How many times a day do you touch a keyboard (number of characters typed) vs. the number of times you touch your computer’s internals? As a computer systems engineer in real-life, I typically spend long hours in front of a computer. The last time I checked, I could type as fast as 100 - 110 words per minute. I have always needed an industrial-strength keyboard. In November of 1984, I was able to purchase my first IBM PC 5170 PC/AT (Intel 80286 processor at 8 MHz (.008 GHz) with a 30MB (0.03 GB) hard drive, and 512K (0.5MB) of RAM for $9000. Little did I know that I would still be looking forward to using the same keyboard in 2006 (i.e., TWENTY TWO (22) years later). Today’s new entry-level computers (Intel Pentium 4, 2.8 GHz, 40GB of hard drive, 256MB of RAM) start at $399. Computer manufacturers bundle these systems with cheap, lightweight "free with purchase" keyboards. As a cost-savings measure (in other words, in order to maximize their profit ) they can not justify anything more than a $5 - $7 keyboard with the belief that most people will not notice the difference. The first thing that I do when I setup a new computer for myself, is re-attach my very durable 1985 IBM model M keyboard (serial #5548). Keyboards are differentiated by the types of key switches used. Key switches are the part of the keyboard which allows the user to press an individual key and then convert mechanical force into electrical signals. When typing on an mass-produced "rubber dome" keyboard, each key press causes a elastic rubber pad with a carbon center to make contact with conductive points on a plastic sheet. The only feedback that a user receives to verify that a key has been pressed is the visual appearance of the character on the See less »
