You're refering to NiCad "memory".  The effect is real but I've never heard
it taken so literally.  You should try and let your battery run down as much
as possible before recharging but I think the notion that if you recharge
once before the battery is drained it will be ruined is extreme.  I have a
set of rechargable batteries for my walk-man (Nicads are Nicads) which are
supposed to have a three hour life.  I try to use them up before I recharge
them but sometimes there is still juice left in them when I charge them.THey
still usually give MORE than the rated three hours.  In other words it's
something you have to be careful about but nowhere to the degree you mention.
I'm not a battery engineer but that's been my experience.

I've had a Librex review unit for a year and a half.  It still works,

general, it has been fine.  More importantly, it travels well.  The modem
works in modem mode and in fax mode.  I can read the screen.  What else
can you ask for in a cheap notebook computer?

Does anybody have any experience with high speed data communcation
under DOS and/or windows 3.1 on the Toshiba 3300SL laptop?  What about
the 1850?

From what their tech support told me, the 3300SL does not contain a
16550 UART chip (or other fifo chip), but neither does it contain a
traditional 8550(?) UART.

So my question is, is this machine useful for high speed network
connectivity to a network through SLIP?

Store them charged. Try to recharge them every few months. 

You must charge nicads once in a while because:

a) nicads lose charge slowly sitting on a shelf.

b) if you let nicads become *totally* discharged you run the risk
   of cell reversal. The reversed cell will then no longer take a charge.
   This is what really kills most nicads, not 'memory' problems.
   Running down nicads is good, but not _all_ the way down to zero.....

A trick I use is to plug the trickle charger into a cheapo light timer that
gives them 1/4 hr per day. This keeps them from losing charge when stored 
without charging them continuously, which even with a trickle is really too
much (you want just a few milliamps for storage, most trickle chargers have
to be designed to recharge in 12 hrs (overnight)).

'Fast' charge nicads, like those in your cordless drill, etc. that can be
charged in under an hour are even more lossey than regular nicads and
need recharging in storage more often.

If you get a dead pack, open it up and measure the voltage on each cell, often
just one cell has reversed (where you a bad boy and discharged it completely)
and you can just replace that one cell.

Good luck,
paul

The ThinkPad 700 does not have PCMCIA slots, unfortunately.  Those two
slots you saw are probably for the DRAM cards.

I suspect it's only 16-bit since the processor is 16-bit externally.

IBM is using their SLC chips in a lot of machines.  IBM developed the
design with Intel's blessing.  Note that IBM's 486SLC is a different
design than the Cyrix chip of the same name.  The most notable
difference is the 16K cache in the IBM version vs. the 1K cache in the
Cyrix version.

Not true. A 386sx-16 can NOT possibly handle 14.4k connections (1700cps
transfer speed) without dropping characters. The only way is to get the
16550 chip. On my 386-25 I also can't do 16.8k (2000cps) without the
16550.

Nope, it won't speed up anything. The 16550 would only make the flow
smoother and not make it lose characters.

According to the manuals of devices that use NiCad batteries, all of them

while (every 6 months, depends).

The way I figure is: if the battery "remembers" shallow discharge, one
should not charge it until it is fully dischared.  But I haven't heard of
anything about "remembering" shallow charging.  So I suppose you can
charge it a bit, but make sure it is again fully discharged before you
charge again!

The following is a brief description of the HP DeskJet Portable printer:

   The HP DeskJet Portable printer offers the same performance and
   laser-quality printing as the top-selling HP DeskJet 500 printer
   in a compact unit that is about half the size of a notebook PC
   and weighs only 4 pounds.  It may be purchased by itself or with an
   optional automatic cut-sheet paper feeder, which also weighs 4
   pounds.  The stand-alone printer is $599 (U.S. list) and the
   feeder is $99.  For transport or storage, the assembled printer and
   sheet feeder fold down into a compact traveling unit, about the
   size of a notebook computer.  The printer is expected to be
   available in the U.S. on November 1.
   
It uses the HP 51608A Black Print Cartridge.  The optional sheet-feeder
will hold up to 50 sheets, depending on the media type.

The technical data sheet can be obtained via fax by calling 'HP FIRST'
at:
      (800) 333-1917  (U.S. & Canada),    or    +1 (208) 344-4809

It operates 24-hours.  You must have a touch-tone Group 3 fax machine.
Just follow the voice prompts.

The document ID for the two-page data sheet is "2306".  I used the
following series of button presses (your mileage may vary):

   1        (select section #)
   1        (select doc ID)
   2306

A passive matrix display has one transistor for each row, and one for
each column.  It activates a pixel by using the corresponding row and
column transistors.  It activates the whole screen by scanning quickly
through all the rows and columns.

An active matrix display has a transistor for each pixel.  Active
matrix displays have much higher contrast and faster response times
than passive matrix, but they are quite difficult and expensive to
make since they have about 300 times as many transistors as passive
matrix.

Recent issues of PC Magazine and PC World have had good articles about
the different display types.

The serial port is the low man on the totem pole when iit comes to
processing interrupts. Doing file transfers at high speeds, characters
are sometimes lost because the serial port isn't serviced fast enough.
A 16550A has FIFO buffers which reduces this problem, when used with
telecom software which recognize and use them.

On AT-class machines - 16450 or equivalent.
