Well, the Model M is just a slightly inferior imitation of the Model F, which is just a slightly inferior imitation of the beam spring, which is just a slightly inferior imitation of the Selectric, which they did mention.

1934 – I recognized the picture – it is actually, according to the Library of Congress entry (http://www.loc.gov/pictures/collection/npco/item/npc2008007802/), of an Atwater Kent radio factory.Show Image(http://lcweb2.loc.gov/service/pnp/npcc/27300/27302r.jpg) (http://www.loc.gov/pictures/collection/npco/item/npc2008007802/)
Actually, the Model M generally has a better chassis design than the Model Fs (especially the terminal boards: the Model F terminal is so weak in spots that it easily cracks: MorningSong had hers crack sadly). But the Model M terminal boards are sturdy.
The idea that IBM kept degrading the technology (or trying to imitate the selectrics) is a little bit of a common misconception. Computers were a lot more expensive, so, manufacturers just made better key switches... that's why you also had ALPs... was apple trying to imitate typewriters with the ALPs switches? No.
That's only for a single keyboard. For others, they're equal, or in favor of the Model F.
Except that the patent for the Beam Spring says outright that they were emulating a typewriter.
I'd like to see that where they say they're trying to emulate a typewriter with the beamspring.
Recently, electronic keyboard advancements have made these units more reliable and less costly than prior mechanical keyboards. However, it is desirous for the electronic keyboards to have the same tactile response to an operator and function in the same manner as the prior mechanical keyboards since most operators are trained on and are familiar with the prior mechanical keyboards.
*Wait what, RISC is still the basis for most processors today? Not really.
From IBM's patent, US 4,274,752,
*Wait what, RISC is still the basis for most processors today? Not really.There are many more embedded systems and handheld devices (such as iPhone, Android phones, etc) than personal computers, and the the leader there is the ARM, which is a pure RISC. The PowerPC is in most games consoles (PS2, PS3, GameCube, XBox360 and Wii). The original PlayStation and the Dreamcast also had RISC cpu:s.
*DeepBlue actually had a human player assisting it; Kasparov attests to this.So? Deep Blue did the "thinking". The man moved the pieces and entered Kasparov's moves into the computer.

It's not obviously right, though; the great mass of 8-bit processors are mostly not RISC.
PS2 is not PPC, it's MIPS.
DEC LK-201 had plastic rivets in 1982 unfortunately. It also had the Model M's layout, but that's a story for another night.It had a layout similar to the ISO version of the Model M... but with only one key where "Scroll Lock" and "Pause" would be, Esc to the left of Caps Lock (which is the Ctrl key instead), two extra function keys, the cursor keys one key position higher, and four extra keys over the numeric keypad like on the Sun keyboard...

and no Ctrl or Alt keys on the bottom, but Compose Character about where the left Alt would be.
Have I missed anything?

ch_123 has been told! oooooh.
That's the second time he's been... somewhat wrong so far.
#1 saying the Model F AT wasn't the same connector as MIDI.
#2 saying the DEC was the same layout as the M.
Function keys on top, inverted T arrow keys and editor keys in between the alpha block and the numpad. Sure the alpha block may be different, but the Model M was really just an IBM-ized version of the LK-201I can see your point.
Are you seriously telling me that you didn't already know you could use the 122 on your PC?I have a 3270/PC 122 model F, and a terminal 122 model M. But I had no convenient source for a microcontroller to use to build a new keyboard controller or anything on the order of a Blue Cube.
It's a real terminal keyboard - the only difference is the part number.So it won't be generating break codes, then - like the Model M terminal keyboard, the wiring mod will also require a modified keyboard driver, I take it?
This raises a point though - how did the 122 key interface with the AT 3270?My understanding was that the AT/3270 had a lot of custom software in it; not only the terminal emulation program, but there were also changes to the operating system to let it run in one window while the terminal emulation ran in another.
Would you list a technology that you sold off (and is currently still being manufactured today) as one of your greatest achievements??Well, the video did list the IBM PC as one of IBM's greatest achievements.
