Greetings and welcome to an LGR thing! And this delightful thing is the IBM

ThinkPad 701C, released in March of 1995 starting at a price of

$3,700 US dollars. And it has one of the best

mechanical gimmicks of any computer ever made.

*sliding, clicking in place of the mechanism*

That is one of the most satisfying combinations of sight, sound, and feeling I've

experienced in a piece of technology. And a big thanks to Sam for letting me

borrow this fantastic machine for this video. Because yeah these are not easy to

come by, especially in his decent shape as this one is. And it really is all

because of that innovative keyboard mechanism. The 701 ThinkPads were the

only ones to have ever come with this keyboard, which by the way was branded as

the TrackWrite by IBM, but it's more widely known as "the Butterfly

Keyboard." Yeah I just can't stop messing with this and looking at it. And even looking

closer here, look at this piece of metal that moves around when you open or

close the computer. The lid moves against this metal piece right here which slides

up against another piece and then the keyboard's two halves either open or

closed in unison. Ah it's wonderful, and so was the person that originally

conceived of the idea: the late inventor and mechanical engineer Dr. John Karidis,

who thought up the idea by playing with building blocks with his daughter. The

story goes there were two triangular pieces that, when moved side to side, gave

him the idea that IBM was looking for for a keyboard that could fold up and

become smaller. He immediately jotted down the idea and

went back to the IBM Research Division in Westchester County, New York. And in

every sense of the phrase it became an instant hit with the design receiving 27

different awards. And there's even one on permanent display at the Manhattan

Museum of Modern Art, one of the very few computers to have that honor.

"It belongs in a museum," indeed! But before we dive into more technical details

let's take a trip back to the first half of the 1990s, where there was a growing

industry trend of releasing ultra portable notebook computers, often

referred to as subnotebooks. Machines like the Compaq Contura Aero, the

Gateway Handbook, the HP OmniBook, and the Toshiba Libretto were notable

examples, all of which attempted to combine the usefulness of MS-DOS and

Windows 3.1 with the smallest footprint and lightest weight possible, combined

with the color LCD screens of the day which ranged anywhere from seven to nine

inches or so. And of course there were several compromises that had to be made

in order to make this happen, such as removing standard sized parallel and

serial ports and all sorts of other ports, forgoing the internal floppy drive,

and relying on docking stations and external add-ons to reintroduce those

features as the user desired. And another obvious way to bring down the size was

to decrease the physical dimensions of the keyboard itself, fitting more in line

with the 4:3 aspect ratio of the displays so as to minimize bezels,

but also making the keys smaller and more cramped. Naturally IBM wanted in on

the action and experimented with the form factor as well with machines like

the IBM ThinkPad 500 in 1993. But as with many subnotebooks the compromised

keyboard and screen meant that it was less comfortable to use for any length

of time for any serious work. And considering this was geared largely

towards business users on the go this was not great. And that's why the

introduction of the TrackWrite keyboard made so much sense for a particular need

at a particular time in the 90s. By packing away the keyboard when the unit

was closed you could have both the small footprint for portability and have a

full-sized keyboard for ease of use. And then combined with a slightly larger VGA

display that was brighter and sharper than previous models, and the 701 was

precisely the right computer for precisely the right moment.

Well, a portion of the right moment at least, because while it earned plenty of praise

and actually became the best-selling notebook of 1995, it only

lasted about a year on the market. IBM announced to the 701 line's

discontinuation in February of 1996, ceasing production in June of the same

year. And there were a couple of reasons for that. For one thing the 701 was

originally meant to come out in 1994 right at the height of the 90s subnotebook

craze. It would have made plenty of sense then but by the time it was on the

market in 1995 customer preferences and available technology were quickly

changing and left it behind. Within a matter of months,

the 701 lost a lot of its appeal with the arrival of well-built 12 inch LCD

panels, which were not only bigger and more desirable, but they also fit in with

a full-size keyboard a little bit more. To quote the board's creator, mister

Karidis: "the butterfly keyboard was no longer necessary because people moved to

larger displays. Where the butterfly approach makes sense is where you want the

largest keyboard possible in combination with an 8 or 10 inch display." And if you

look at reviews from the time period they often mention that the 701 was also

hampered by the 486 CPUs offered with the device. Depending on your benchmark

of choice even the fastest 75 megahertz DX4 CPU benchmarked at

about the same speed as competing systems' 50 megahertz DX2. The 701 also

used nickel-cadmium batteries, which were rather dated by 1995 and only lasted one

hour and 40 minutes or so when two hours was considered by many as the minimum

acceptable runtime. But that sure didn't stop people from buying it for the time

it was on the market and becoming quite the computing collectible in later years.

And not just collectible in a desirable sense, these are not cheap either,

currently running anywhere from $400 to $900 for a nice 701C and a bit less

than half that for a 701CS model. Speaking of which, yeah, there were two

main models. The main differences between the C and the CS is that the C came with

a 10.4 inch TFT active-matrix LCD screen while the CS used a dual scan

LCD screen of the same size. They both have a native resolution of 640x480

but the CS model's dual scan monitor was a

cheaper and lower quality type of passive-matrix panel that isn't suited

for much beyond static imagery. But between the two models there were a

broad range of configurations available, starting with the processor which was an

Intel 486 in either the DX2 or DX4 models running at 50 or 75

megahertz, respectively. The one I have comes with the latter. You also have the

option of four or eight megabytes of RAM installed onboard and it supports up to

32 megs of additional RAM. As for the hard drive you got the option of 360 or

540 megabytes with a 720 meg upgrade option available from IBM. And you had a

choice between a couple operating systems, this one being configured with

*startup sounds commence, with hard drive noises and PC speaker beeping*

*Windows 3.11 "tada!" startup sound plays*

Or, OS/2 Warp was available as an option on the

75 megahertz model. You also get a one megabyte CT65545

VESA local bus graphics chipset, a 16-bit ES688 AudioDrive Sound Blaster
