The Laptop Computer

In a previous section, I noted how electronic programmable scientific calculators started out as devices for the desktop, and then became pocket calculators.

I had briefly mentioned the Osborne I, the Kaypro, and the original Compaq, which were portable, although portable computers of the type called "luggables". But as we all know, computers didn't stop becoming available in smaller sizes there: the laptop computer came along, and even the pocket computer - and while the pocket computer was not a long-lived product category, the personal organizer was seen as a bit more practical, and of course, these days we're all carrying full-fledged computers in our pockets; but as we can also make telephone calls with them, we call them smartphones.

On the right is an image of the EPSON HX-20 portable computer. Note that it has a (thermal) printer, a display, and a micro-cassette drive for external storage, to make it not merely the first easily portable computer, but also the most complete one in that class. Originally released in Japan in 1981, it reached the North American market in 1982.

(Incidentally, the image is from an advertisement that originally occupied two pages in the magazine in which it appeared; it has been extensively retouched to replace the portion lost in the gutter between those pages, and so I apologize for any unintended inaccuracies. I felt it was worth the trouble, given its historical importance as the machine that started it all.)

A similar computer made by Kyocera came out shortly after, and a heavily modified version was offered to the Western market. This one eschewed both the printer and the cassette drive in favor of a larger display, and it had a keyboard with what I view as the ideal arrangement for a computer keyboard: typewriter-pairing rather than bit-pairing, and with both shift keys, the back space key, and most especially and uniquely, the Enter key, all in the positions where they would be found on an electric typewriter, for the greatest convenience in touch-typing.

It is the TRS-80 Model 100 of which I speak, pictured at left.

At first, when I started work on this section, it didn't seem that I could feature any typical or ordinary laptop here. However, while the Toshiba T1000 was not the first laptop computer to be compatible with the IBM Personal Computer, when it was introduced in 1987, it was both so light in weight and reasonable in price compared to what was previously available as to make a laptop computer a reasonable option for many more computer users than had previously been the case.

Also, while it was quite compact and light for its day, it is still significantly different in appearance from the laptops of today, as while the display unfolds from the keyboard, the display and keyboard together occupy a space at the front of the laptop rather than the whole of its depth as is the case with most laptops today.

Most people reading this page know what a laptop computer looks like, and if they have forgotten what a smartphone looks like, they can reach into their pockets!

So, why don't I instead include an image of something which at least some of the readers of this page may not have seen, or if they have seen it, or pictures of it in magazines, they at least may no longer remember it?

Something which, at least for its time, was incredibly unique and unexpectedly powerful for its size?

And so, from October, 1989, I bring you an image to the left of the incredible Atari Portfolio!

Unfortunately, it was not all that successful, as far as I recall. Although this handheld device was compatible with an IBM PC running MS-DOS, the fact that it had a text-only display with only eight lines of text meant that a lot of software for the IBM PC would not run on it, and that left many potential purchasers unsure as to what they could actually use it for - or, perhaps more precisely, what the value of presumably paying extra for IBM PC compatibility would be under such circumstances.

On further reflection, I think what happened was an error in marketing. The unit was made MS-DOS compatible so that people would be reassured they could transfer information, using an attached floppy drive, from their PC to this device in order to use it anywhere they could carry the small device. But by claiming it was compatible, even though clearly there would be much PC software that couldn't run on it, potential customers focused on the claim of compatibility, seeing it as a gimmick, since compatibility was generally defined as the ability to run any and all software for a the system one is claiming to be compatible with.

So people did not see the device on its own terms, and understand what the level of compatibility it offered was for; the means used to reassure people about its ability to use data from PCs led to confusion that hindered interest.

But come to think of it, when it comes to small computers, I can think of one other one that is special. The Sony Vaio UX is famous for being a PC-compatible computer able to run Windows XP that can be worn on one's wrist!

At the time, this was simply amazing and unbelievable. But while it was an impressive feat, it was also expensive, and not many people in the North American market, at least, felt they had any reason to pay a price premium for a level of portability that interfered with usability.

In other markets, however, portability is more highly valued, and thus a lot of interesting mini-laptops are available in Asian countries that never make it to North America.

Thus, the Eee PC from ASUS, a small and thin laptop, was noticed when it was available in North America. The first model came with Linux, but the second model, the Eee 900, which came to North America in late 2008, ran Windows.

As far back as 1995, IBM made the PalmTop PC110, which was only available in Japan.

In addition to the Toshiba T1000, there is one other laptop computer with a conventional form factor that is so historic that I feel it is worth mentioning and picturing here. Shown at right is the Data General One laptop computer. The portion with the keyboard does extend somewhat behind the screen, so the unit doesn't have the modern "clamshell" form factor, but it was still remarkably thin and light for its time.

The Data General One was a technological feat when it came out in 1984, and thus was somewhat expensive (initial price $2,895 U.S.) compared to the ordinary and less compact portable computers of its day. The technology wasn't quite ready for it; its liquid crystal display had to be made from four individual panels carefully joined together.

Data General, of course, is much better known as a minicomputer company, coming out with the Nova minicomputer after Edson de Castro left DEC over a disagreement about the direction the company would take in developing a new 16-bit computer. Eventually, of course, DEC developed the PDP-11, which was extremely successful and influential, and very different, architecturally, from such 16-bit computers as the Honeywell 316 or the Hewlett-Packard 2115, which were both very similar to such existing DEC minicomputers as the PDP-9.

The architecture of the Nova was a more modern one than that of those other computers, but it was very different from that of the PDP-11. The Nova was followed by an upwards-compatible and higher-performance computer, the Eclipse.

Another claim to fame for Data General has to do with a later machine in the Eclipse line. The Eclipse MV/8000, introduced in 1980, and pictured at left, was Data General's answer to the VAX from the Digital Equipment Corporation.

Digital Equipment Corporation's first machine in that series, the VAX-11/780, announced on October 25, 1977, included the ability to execute programs for the PDP-11 when running in 16-bit mode. When running normally, in 32-bit mode, however, its instruction set was completely different.

Advertising for the Eclipse MV/8000 emphasized a feature of that computer: the new instructions which performed 32-bit addressing or 32-bit calculations were additions to the existing Eclipse instruction set; the computer did not work by switching modes.

This unique feature made it possible, when the book by Tracy Kidder, The Soul of a New Machine, which chronicled the development of an unidentified new computer at an unidentified computer company... which happened to have this particular feature... to realize exactly which computer's development she was chronicling.
