| Hi,
I'm a little puzzled as to why a reboot would fix it, if it's
a connection-related problem. Are you rebooting it via software
or the button on the back?
If you're using the button on the back, perhaps it's enough
of a nudge to alter the physical connection...
I'm not a keyboard (hardware) guru, but I've disconnected
my keyboard several times, and perhaps the connector has
a little oxide on it...

| I have tried all that. It has baffled me, and all of my technical
friends. Luckily, a local (the only, sigh..) atari computer store had
a 'garage sale' of used equipment. I picked up a used keyboard (an old
one, from the stf) and put that in. It works just fine, so I guess
something was wrong with the other. The good thing is it only cost me
$4.00 cdn, the first repair i've ever had that's been under 100.

| The keyboard is certainly repairable as I have been in and out of mine several
times. In noting your symptoms, I would suggest you examine the plug coming
from the keyboard that connects to the main board. I have on several occasions
had to reattach one or more wires. I have found that the crimp tends to cut
deeply into the wire and tends to fatigue the connection. It does not take
much to reduce the connection to a single strand. Since the bundle is also
wrapped, a flaky connection can occur as the wire may be held close to the
crimp. Check closely and if you see a questionable, solder the wire directly
onto the crimp terminal. This has worked for me.

| Well, I seem to have a very similar problem to .0 on a 1040STf. Every
so often the Z, X, V, RHSHIFT and CAPSLOCK keys all fail. Switch off or
swear at the keyboard and they all start working again. I took the
keyboard apart to see what connection there was between those keys. I
assumed that each key shorts out a unique pair of pins on the big chip,
so each pin shares a few keys. Sure enough the top right hand pin leads
to Z, then X, then V, this is looking promising, then SPACE (oh!) then
N, M, RHSHIFT, ?, CAPSLOCK, KP0, KP., ENTER. So much for that theory,
any break in the connection should have taken out all those keys.
So I'm really puzzled. Previous explanations (here and in 709.*) don't
seem to explain it.
(Oxidation of contacts): but the keys in question either all work or all
fail, rather than intermittent operation on any of them.
(Static): but that would lead to a permanent failure I assume.
(Funny mouse): This actually looks the most promising, I do have a
Gravis Mouse-Stick. Perhaps it is upsetting the keyboard chip.
Right now I'm sitting in front of a naked keyboard and a pile of
contact-domes. Of course now I can't get it to fail at all, no matter
how much I power down, disconnect the mouse, etc etc.
It's been a year since the last reply. Has anyone had any new flashes
of inspiration on this problem, or should I just buy a new keyboard?
