Well, I got irritated with the keyboard (ever try to use vi without
the Escape key) and jerked it apart. Very gently.
1) I'm certain that it's re-badged OEM, not IBM-built. All the screws,
internal and external, are Phillips.
2) It's not a double membrane, it's rubber cups over a PCB, with foil
inserts in the caps. The traces on the PCB were covered with
unidentified goop. *Only* under the Escape key. I dunno.
3) It works now.
4) Thanks, Tony. Even though this one bore no resemblance to your
instructions, sometimes *thinking* you have a clue is as good as
the real thing.
On to TCP/IP, NFS, and maybe a game or two of hangman.
Speaking of hangman, is it just me, or is the NetBSD port of hangman
purely evil? Come on, now. "Prolegomenous?" Seriously, I've played
hangman on a bunch of different Unices, and the recent NetBSD hangman is
by far the hardest I've ever seen.

IBM's keyboards were always built by Lexmark. Recently (a few years ago),
Lexmark spun off their keyboard operation, which was swalllowed up by
Unicomp. This keyboard was built before IBM spun off Lexmark, which means
it was built by IBM.

The mechanism in IBM keyboards is called a "buckling spring mechanism".

Excellent!

It was a small joke. My private peeve with IBM is that they still
haven't learned about Phillips-head screws.

No, I mean that they're better than slots. Granted that a lot of the
later workstations have mostly hex-heads, in many places it's a plain
slotted panhead. Pretty cheesy on a $5000-$15000 machine.

I've got a T1000XE that just died! It goes through a memory check ok but
then the Hard drive just "clicks" when it tries to boot. I've got an
external 51/4 drive but I guess the boot sequence that I was using looks to
the hard drive first and then just stays there.
Is there any key sequence or other trick that will get me to bypass the
hard drive boot? At least then I might be able to learn enough about the
failure to decide whether to just scrape the machine.
Thanks in advance.

I'll take it that the config is somewhere in a kinda
CMOS-ram. So I would disconnect every battery in the
machine for a couple of minutes to half an hour
(there are always elco's), Then reconnect and reboot
There maybe one ver long pencil-form accu in there, as well
as the regular accu-pack and a lithuimcell or nicadcell for the
CMOS, make sure you disconnect them all!
After rebooting the system the will revert to defaults and
a standard setup an will propably activate the floppy
before the HD again.
Given your description I'd say your HD is dead but if
not so my procedure may also throw away the HD-setup
data in CMOS and you may find it hard to reinstall
a new HD (or the same after repair) if you have no other
source for this kind of info. Maybe this list can help in that case.
I once had a T1200SE that had no harddisk but used
battery backuped RAM. so I'm describing that system,
but given the T1000 prefix I think it must be rather similar.

That T1000XE uses standard 2.5" ATA HD, 20MB only due to
hard-wired bios. Usually Conner. HD is removeable from notebook
without disassembly. Flip over that notebook, there's the hatch
silver label w/ two screws and locking slider, undo all, slide the
hatch (to disconnect HD from motherboard) then take it out. Screws
for holding HD to hatch is hidden under same silver sticker.
CMOS stubby battery is lithium, other one long NiCd "pencil" battery
(made of four NiCd AAAA cells) under the keyboard near front is for
battery-backed ram disk. On Toshiba's cmos, disconnecting cmos
battery, cmos data erase is instantanous.
FYI: this notebook WILL NOT start if main 7.2V battery is not
present or dead. That is for sure because I had this problem.
Toshiba still have utility for setting up CMOS for older series.
Oh yeah, this is one of rare few XT machines that supports 1.44MB
floppies. (!!)

D'oh!! I used Ctrl-[ on some of my DEC serial terminals, until I
found a kbd that still had the function keys labelled, but it never
occurred to me here.
I guess you'd expect IBM to have hex-head screws
(to be undone with a
nutdriver), right?
Anything besides the slotted panheads you find on pre-PowerPC
workstations....
Indeed. Often all you need is the confidence to go in
there and fix it. I
generally tell myself that I can't be beaten by simple electronics or
mechanics. And for some odd reason that's true most of the time :-)
That's usually my attitude, but the last time I took a keyboard apart,
a cheap PC clone, I picked up tiny springs for an hour. Not worth the
hassle.
