(Re: Christian's message about real Model M's)
I've got other Model M's with different part numbers--the Wang model
has "double" keycaps, each with an outer shell., presumably for easy
customization. They all say "Model M".
But to the point of "real" Model M's, have a look at the
clickykeyboard exhibits:
http://www.clickykeyboards.com/index.cfm/fa/categories.main/parentcat/
9230
There you have Model M's from early 1986. In every case, the label
on the underside identifies it clearly as "Model M". Perhaps only
the versions of this keyboard produced in the UK lack the
appellation.
For all I know, "Model M" in British English might refer to an off-
color(colour) joke and so was omitted. Or the person designing the
label for the UK model thought that "Model M" was unnecessary. But
all of the USA-made units that I've seen all say "Model M" on the
label.

Chuck

Well... there was presumably a change in the internal keyboard layout to
accommodate a 102 (rather than US 101) key design. If that fab was done by IBM
outside of the US then it seems entirely possible that they retained important
bits (s/n, p/n and "IBM" text) but that the "Model M" name became lost
somewhere.
(I believe that the 102-key layout was sufficiently generic for most non-US
markets, so it wouldn't surprise me if other non-US Model M's lack the
branding too)
I can't think of a reason why "Model M" would either have been frowned upon
in
the UK or infringed on some other keyboard-related territory that involved the
name. I suspect it's pure fate (and not even a screw-up).

Wandering around the clickykeyboards site, it's quite apparent that
for the keyboards manufactured in the UK, the "Model M" labeling is
missing. US-manufactured ones seem to all have the "Model M" tag,
regardless of 101- or 102-key-edness or date of manufacture.
See, for example, the Spanish examples here:
http://www.clickykeyboards.com/index.cfm/fa/categories.main/parentcat/
11067/endrw/12
I suppose we could say that keyboards manufactured in the UK are not
"real" model M's, but that would open another can of worms...

You tend to find that with USB devices in Linux - they either Just Plain
Work, or are totally unsupported.
I know a lot of people in here don't seem to like USB, but it reduces

I love USB devices, so easy to use and (in my experience so far) absolutely no drivers

I have a small uC device that I made that uses an FTDI USB->TTL
converter. I wish USB was as straight-forward as you describe. I'm
currently running into problems when transferring, very quickly, some
data from the uC to the PC. The problems are related to overrunning the
PC, where the PC isn't scheduling reads from the device fast enough to
prevent drops. At least interrupt-based I/O can "demand" attention from
the cpu at any time, where USB is at the mercy of being scheduled.
I'm now implementing an xmodem-like ACK/NAK block based protocol on top
of USB, in addition to setting USB read-size to the precise size of a
block to obtain more efficient usage.

I'm probably stating what you are already aware of, but on the off-
chance that it sheds some light...
Don't those things have a FIFO--something like 384 bytes?
Regardless, there are two basic modes of operation on those things--
the first is single-character "comm port" type transfer; the second
is block-mode transfer (as you'd see in a storage device). Single-
mode transfers have considerable overhead, severely limiting the
speed. Unfortunately, most of the FTDI development kits include
drivers for only the former mode and not the block mode.
FWIW,

The communication on the PIC side is solved by constantly polling the

We had problems with package dropped every ten seconds or so but we
traced it back to a iproute cache flush that the kernel was doing.
The USB bus is fast but with standard hardware it isn't hard to get the

some periodic maintainancy or there are any other devices using the bus.
Sorry for being a bit OT but just to add a bit of nostalgia to my post,

Amen to that. From a hobbyist interfacing standpoint, there is quite a
bit of HW nwoledge needed to handle USB devices, ignoring the
programming aspects.
Consistency demands that I not reject USB, but I do hope none of the

That's much my attitude too, and not just about interfaces. I see no
reason at all to replace a solution that works with one that's untested
(at least by me) which may or may not have advantages (and often, alas,
has problems). If I have something that does the job I want it to, then

It depends of what you are using. I have a FT-232 here and it is
transparent to me as a serial port. Electricaly it is a bit complicated, but
clearly possible to do bitbanging and creating a usb slave. Look for
igorplug on the net, and see a totally software solution for that.

My Model Ms have a travel-assist bar only for the space bar. The

There's no obvious signs of wear on the shift key mechanism (as compared to
other keys) or on the keyboard itself (i.e. the pillars that support the key)
or other debris which might be fouling things up.
If I put the Ctrl key where the shift key is then I can press that on the
right-hand edge and it works fine (although it doesn't extend out to the right
quite as far as the shift key does). I suspect that it's the 'unsprung'
support on the left hand side of the shift key that's fouling - pressing the
shift key makes it rotate slightly and jam up in the left support.
(I'm not yet sure how the little white plastic inserts on the unsprung key
supports come out, but as a test maybe I can swap one of those in from
elsewhere and see if things improve)

Yep, will do. If that doesn't work then I can just get used to it I
think, it's not really *that* big a deal. Re. Model M itself - it's nice to be typing
on one; I've suffered a
laptop keyboard for far too long! My only criticism of it is that the
right-hand shift key seems to require fairly central pressing in
order to work (i.e. I can't just reach across from the cursor keys
and tap the end) - does anyone know if they changed this (i.e. added
a metal travel-assist bar as with the spacebar, keypad enter key
etc.) on the later models?
I know for a fact that they didn't. Try a mild lubricant.

I've not tried it here yet, but then the two model M keyboards I have here

Probably any dry aerosol used to lubricate locks would be fine, but
not graphite. I find several brands of silicone aerosol at the local
hardware store. I haven't looked for PTFE spray, but I'm not
enthusiastic about the PTFE lubricants that I've used that were
suspensions in an oil base.
I know that the firearms crowd uses various dry lubricants (Dri-
Slide, Eezox, Tetra) but I don't know how they'd work in this
application. Moly disulfide lube like Dri-Slide might be messy,
though.
I'd steer clear of any oil, even watch oil--it'll just attract dirt.
If the crud in my own keyboard is any indication, that's not
something that you'd want.

Does Rubik's cube lube come in a tube? :-)
I think I'm wary of anything used by the gun and automotive crowd just because
the fact that it works on metal doesn't necessarily mean that it won't harm
plastics - but something that says it works with plastics is probably the best
bet.
I do think the problem I'm having is the key binding due to twisting when
pressed - the right shift key does appear to be the longest key that has an
additional unsprung support and yet doesn't have a travel bar beneath, so on
an old keyboard (that's potentially seen a lot of use) it's probably not
surprising that it's the first to have problems.
It's fine if pressed in the middle 50%. The left 25% feels a little less
smooth, but still doesn't bind - it's only when pressed on the right 25% (i.e.
anywhere to the right of the spring center) that it's prone to not going down
(or, once in a while, going down and then sticking in the down position).
I'll see what I can find for dry lubes anyway - if no luck there then I'll
investigate adding a travel bar to the underside of the key...
cheers

What age of Model M, out of interest? I wonder if they added USB support into

Funny you mention that. I'm using an older keyboard, AT-style,
running the AT to a dumb PS/2 converter, then to a mouse-and-keyboard
PS/2 to USB converter of today's $5 variety. Mine does the same thing
now and then. It seems to eat four-five chars or just stop sending

I like my Dell laptop!
The only thing I hated was the dreaded 'mouse drift', caused by the silly little
mouse stick (not sure what it's called) that lerks between the G,H and B keys. I soon
fixed that by going into the setup menu on bootup (I actually had a problem with my HD
that meant I had to go in there, presumably some trojan or whatsit had corrupted an
important portion of it, which was fixed once settings were resaved).
