IBM is obviously the company everyone thinks of first when we talk about the IBM PC -- after all, IBM is right
|
|
there in the name. They designed the thing. So IBM, and in particular the folks who worked in Boca Raton at IBM's
|
|
Entry Systems Division in the early 1980's, deserve all the credit for defining what eventually became known as the
|
|
Industry Standard Architecture (ISA) PC platform.
|
|
|
|
However, the dawn of the PC era also saw the rise and fall of many other personal computer companies.
|
|
One of the more exceptional companies from that era was COMPAQ. It would be a mistake to dismiss COMPAQ as just
|
|
another company that set out to "copy" or "clone" IBM's design, because from the very beginning, COMPAQ's ambitions
|
|
went beyond mere imitation. They were really in the *compatibility* business.
|
|
|
|
Innovation in the PC industry would not have been as rapid and diverse if IBM had been the only supplier of
|
|
compatible machines and accessories. If IBM had been able to control the market, they probably would have continued
|
|
some of the monopolistic practices they had perfected in the mainframe era. Market control might have been a win for
|
|
IBM, but it almost certainly would *not* have been a win for customers.
|
|
|
|
In 1982, the founders of COMPAQ took a big gamble, by reportedly investing around a million dollars to create
|
|
a system that mimicked IBM's without infringing on it. I don't know if COMPAQ pioneered the concept of "clean room"
|
|
design, where the engineers designing and coding have no direct contact with the hardware and software they're cloning,
|
|
but they were certainly successful.
|
|
|
|
But that wasn't COMPAQ's most important contribution. That was just the price they had to "pay to play." Armed with
|
|
compatible hardware and software, COMPAQ proceeded to innovate in ways that IBM did not.
|
|
|
|
Look at COMPAQ's first product: the COMPAQ Portable. For starters, it was *portable*. And unlike
|
|
IBM machines, it didn't force you to choose between a higher-quality text-only (MDA) display or a lower-quality
|
|
graphics-capable (CGA) display. COMPAQ improved on IBM's mutually-exclusive display choices by creating a monochrome
|
|
display that could display both high-quality text *and* graphics.
|
|
|
|
IBM released their own portable unit a year later, but it looked suspiciously COMPAQ-like, and it lacked COMPAQ's
|
|
innovative display.
|
|
|
|
That tradition of innovation at COMPAQ continued for many years. Sometimes they even seemed *more* concerned about
|
|
compatibility than IBM did. For example, faster machines sometimes broke speed-sensitive floppy-based copy protection
|
|
schemes, which COMPAQ tried to avoid by automatically *slowing* the machine down whenever a floppy drive was spinning.
|
|
|
|
To my knowledge, IBM never bothered with such a feature -- maybe IBM was simply being pragmatic, or perhaps they were
|
|
just a little arrogant, operating on the theory that if the universe revolves around IBM, then the planets will
|
|
simply realign *themselves* (translation: software vendors will release new versions if they want to remain IBM-compatible).
|
|
|
|
Sadly, COMPAQ was ultimately absorbed by another behemoth -- Hewlett Packard -- and then simply disappeared. Today,
|
|
all we have are the memories.
|
|
|
|
### Speaking of Memories
|
|
|
|
In particular, Read-Only Memories: we have precious few of those, too. I finally obtained
|
|
a [ROM Dump](/devices/pcx86/rom/compaq/portable/) from COMPAQ's first machine, the COMPAQ Portable, but I had to buy
|
|
a system board on ebay to get it. Considering all the effort (and money) that COMPAQ invested in writing that code,
|
|
it's a bit depressing that these things haven't been properly preserved and memorialized.
|
|
|
|
Looking ahead to the day when PCjs will be able to simulate the original COMPAQ Portable, I thought it would be a good
|
|
idea to create my own roughly chronological list of [COMPAQ Machines](/devices/pcx86/machine/compaq/) from the 1980s,
|
|
since they are all machines I would like to see PCjs eventually support:
|
|
|
|
- COMPAQ Portable
|
|
- COMPAQ [Portable] Plus
|
|
- COMPAQ DeskPro
|
|
- COMPAQ DeskPro 286
|
|
- COMPAQ Portable 286
|
|
- COMPAQ Portable II
|
|
- [COMPAQ DeskPro 386](/devices/pcx86/machine/compaq/deskpro386/)
|
|
- COMPAQ Portable III
|
|
- COMPAQ DeskPro 386/20
|
|
- COMPAQ Portable 386
|
|
- COMPAQ DeskPro 386/25
|
|
- COMPAQ DeskPro 386s
|
|
- COMPAQ DeskPro 386/20e
|
|
- COMPAQ SLT Series (SLT/286)
|
|
- COMPAQ DeskPro 386/33
|
|
- COMPAQ LTE Series (LTE and LTE/286)
|
|
|
|
It's hard to stop at this point, because COMPAQ produced other innovative 80386-based systems, like those in the LTE
|
|
and LTE Lite series. But I think I need to stick to my original plan and draw a line at the end of the 1980s.
|
|
|
|
### Regarding The COMPAQ Name
|
|
|
|
As best I can tell, COMPAQ preferred to print its company name in all-caps, so that's my practice as well.
|
|
|
|
However, it seems that sometime between the release of [COMPAQ MS-DOS 3.10](/disks/pcx86/dos/compaq/3.10/) and
|
|
[COMPAQ MS-DOS 3.31](/disks/pcx86/dos/compaq/3.31/), there may have been a shift in policy. Both products still
|
|
called themselves `The COMPAQ Personal Computer MS-DOS`, but in 3.31, the copyright string changed to
|
|
`Compaq Computer Corp.`
|
|
|
|
Their all-caps practice also extended to product names (eg, `COMPAQ DESKPRO`), at least in their marketing literature.
|
|
Contemporary news stories, however, tended to lower-case the product name (eg, `COMPAQ Deskpro`). I've decided to
|
|
split the difference and use mixed-case where it seems appropriate (eg, `COMPAQ DeskPro`).
