Cheap Computing, The Future of TI Calculators
|
Posted on 26 August 1998
The following text was written by S.T.L.: Let's see, it's late at night (or
really early in the morning), and I'm reading Wired (a good magazine). September 98, pg 212,
if anyone's interested. Nicholas Negroponte writes: "But the potential for very low
cost computers is wildly more than we have made of it. Why? Because inexpensive computing is
a crummy business. [description of low profit margins, etc] US companies just do not know
how to tackle the low end. And by 'low end' I don't mean the much vaunted sub-$1000 computer
- I mean PCs that cost less than $100." I argue here that Intel, and the other big
chipmakers, are good at the very high end (can't wait for the Merced to arrive), but their
attempts at "Network PCs" and (for example) the Intel Celeron, are laughable. Thus we
shouldn't expect very low end computers to come from them. I say that the "PCs that cost
less than $100" that Negroponte speaks of are ALREADY HERE, in the form of TI calculators.
Just as with PCs that range from $2000 to $5000, one can pay less than $100 for a low-end TI
(like an 81), pay $100 for a TI-85 (good general purpose calc) or splurge and get a $200
TI-92. Or $275 TI-92+. Calculators used to be very simple. Add 2 and 2, please.
They were electronic abaci. Nowadays, I would say that the TI calculators aren't abaci
anymore, they are small computers in their own right. This isn't like saying a car is a
computer, because it contains microprocessors. TIs (my experience is with the 85 and the 92)
can do most anything an Apple computer can do (the old ones), and sometimes faster. PDAs
will never be successful until they can act as a universal computer. I also would say that
TIs and their decendants may replace PDAs as the small electronic devices of choice. I take
notes on my TI-85 when I don't want to remember something. And small videogame systems, like
the old 8-bit Game Boy. For example: In the "olden days", someone could get an Apple to
do math for them. TIs do this much better, and they fit in your pocket. (Well, large
pockets.) In the "olden days", someone could take notes on a PDA. TIs do this, and more. In
the "olden days", someone could play games on a Game Boy. TIs have a wealth of (mostly free)
games. And like a PC, they can connect to a large network of new programs (via a PC),
and communicate directly with one other TI. (Like a modem-modem connection.) And remember -
this was all done WITHOUT Texas Instruments really intending this to happen. The first
assembly shells exploited loopholes that let them get to the core of the processor. Texas
Instruments saw how people loved the computing capabilities this gave them, and then put
assembly support into the 86 and others. The low-end future of computing is probably within
TI's reach, if it can keep costs under (say) $300 max, and be even MORE versatile than the
current TIs. If anything, the history of computing shows that *open architecture is the road
to success*. IBM let everyone clone their computers and make OSes for it. Apple was hissy
and only allowed itself to build their computers and write OSes. (Allowing cloning a decade
later didn't help any). Result: you're probably reading this on a system that is
IBM-compatible. Even more so: the current success of the "Wintel" systems is because
Microsoft made a shell for MS-DOS that made it friendly, and powerful. Texas
Instruments probably planned to just make a calculator when it made (say) the TI-85. Yet
because it left a loophole, people made shells, and OSes for it, and programs. And they did
all that for NO pay at all. Just people hacking up programs in their free time. TI didn't
even make it convenient to exploit that loophole, and yet the various assembler shells have
large bases of support. (How large, I don't know). As processor costs go down, Texas
Instruments will be able to either reduce the price of their calculators, or add new
features. Weasels have developed memory expanders and figured out ways to get TI-85s to make
sounds. And that's just with one link port. Imagine a TI-X that had the following features:
- 1 MB user RAM, 3 MB archive RAM
- 20 MHz processor
- Headphones port
- Calc/PC Link port
- Calc/Calc Link port
- Memory Expander port
And perhaps an
extra port, for future devices such as IR links, pads that could allow handwriting
recognition, etc. I don't believe the name "calculator" would apply to such a device, it
would truly be a low-end computer. The interesting thing is, (except for the increased
on-calculator storage and processor speed), all these things are here already in the TI
calculators: more ports would just make it more convenient. Right now, the TI port functions
as the sole "extra port for future devices", and it wasn't really intended as such.
My opinion is, that Texas Instruments should also finally ACKNOWLEDGE that TI calculators
can do other things than calculate, and in future TIs make it easier for people to add
features to TIs. Look what's happened so far. What's your opinion?

I think that what many people fail to realize is that the TI graphic calcs are using the same processors that were used 10 years or so ago, though with (in my opinion) much better functionality. (and the local library wonders why all the Z80 programming books are disappearing...)
I feel pretty certain in predicting that in another 10-15 years we may see devices (not necessarily calcs, but something that does much more than a calc or pda) that rival the power of pentium class systems.

Hm. It looks like there are improvements over time in computing. I agree with not encountering actual Penti, but an ARM with a similar performance is real close now. For example a typical 94 MIPS, 32 bit ARM7 clone microcontroller with built-in mem/caches/USB/other goodies is easily available and also affordable for $12-$20 depending on manufacturer. Those "old" architectures even when built with a mid-range silicon process have a remarkably small die size *and* have a low power consumption (100mW typical at 94 MHz for one I've seen), and varies with speed/idle time. (Note that a 386DX eats 4W!) Passive cooling (with the optional use of a heat-sink) should do for any device <1W, but <.1W should stay extra-cool. I personally favour CPU with low voltage/low power that have a sleep mode, thus can optimize battery-life versus usage. BTW. rechargable batteries: not a bad idea, but for an 8 bit B/W calc?? Why does it eat so much? A low power and h*** cheap 8-bit micro needs <4mW @ 20 MHz running, <.001mW in idle. The LCD isn't an active matrix color TFT neither... (If I recall ok, TI Electronics has some 8-bit micros too)
I hope someone will construct a LP and cheap ach. with modern tech. It _would_ be *cool*. ;-)
[Uhm... do you need line breaks in these things!?]

I have to admit, being 10 years after this post, I laughed when reading this with my TI-84+Silver in front of me (two link ports, it came with orginizers and games, and has an insane amount of memory). I had actually been thing about this topic before I read this article, though. Calculators were made to do simple things in math so people could focus on the harder stuff. As more and more stuff became "simple" calculators advanced to fit that, and the trend will continue. In the future, the "calculator" form of computers (meaning the classroom/tool type with it's game and program area mostly comprosed of hobbiests making free games) will reach the computing level of the PC/game system forms today, but it will still be seen as a lesser form, as the PC and game system forms will be far more advanced.

I personally don't see anything wrong with having
a calculator as a "portable PC". Your PC could turn into some sort of docking station for your calculator. In my opinion, the pros of this would be, you could have a wealth of information in your pocket in the form of a calculator. I know, who really wants that? There's more pros, and yes, I would want that. But that's just me. Here is a question - would a TI-86 be worth it if it had electroluminiscent backlighting, a 512k, 1meg, or even 2meg memory expander, an AC outlet adapter, an NPO capacitor (supposedly making it about 4x faster)? Whoever has beefed their TI up with all that apparently wants their calculator to be -something- more than what TI forsaw. I'm actually thinking about adding all those bells and whistles myself, actually.
