I too, and two of my colleagues, have been having trouble with keyboard stoppage as we type certain sequences fast. The sequence in particular is "stop" (which is typed a lot into VersaTerm for our mainframe software) and the final "p" sometimes doesn't appear. If you notice, and type "p" again it still doesn't work - you need to type something else to 'unjam' the keyboard. I reported this to Mac Technical Support in April and they suggested VersaTerm might be dicking with the keyboard map, but I doubt it (and so does Synergy - the publishers of VersaTerm). I also have had this happen once in Think C as I was typing "top" (though it's possible VersaTerm was in the Multifinder background at the time - I don't remember). It's easy to type the "op" sequence very fast - the two keys are right next to each other - but I can't get this to happen more than about once a day or two. It's totally real, but elusive. I'd love to find the problem and get a fix ... Gavin Eadie, U of Michigan Information Systems

So, here are the two combinations. The idea is to type the
characters as fast as possible, either one after the other, or all
together. For the first combination, typing all three together
produces wierdness about 70% of the time for me.
Combination one
u t space
combination two
o m p
Well, I've run into about the same problem, duplicated on 2 SE/30's
with extended keyboards... In more than one program, if I'm typing
quickly and type 'o' and another key at more or less the same time,
the keyboard freezes up until I wait a second or so. Usually I have to
hit delete, or some key other than the space bar... Very confusing.
Also, sometimes if I type to and hit the space bar, it comes out too
for no apparent reason.

I too have had problems with an extended keyboard on a mac SE/30 (system 6.0.5) along the lines of those reported in the following two notices: In article <1990Jun30.183958.12053@terminator.cc.umich.edu> Gavin_Eadie@um.cc.umich.edu (Gavin Eadie) writes: >In article <ALAND.90Jun30114059@chaos.cs.brandeis.edu> >aland@chaos.cs.brandeis.edu (Alan D Danziger) writes: >> Well, I've run into about the same problem, duplicated on 2 SE/30's >> with extended keyboards...

When I first noticed the problem, I attributed it to my sloppy typing skills and thought that I wasn't striking the keys firmly enough or not at the 'proper' angle. But this 'jamming' problem (just had it there when typing the oh in 'problem') convinced me otherwise. It is very frustrating too. >I reported this to Mac Technical Support in April and they suggested >VersaTerm might be dicking with the keyboard map, but I doubt it (and so Happens anywhere as far as I can tell. I use WK, so VersaTerm definitely isn't the problem here. >It's easy to type the "op" sequence very fast - the two keys are right >next to each other - but I can't get this to happen more than about once a As an aside.... Experienced typists actually type 2-handed combinations fastest (see _Expertise in Typewriting_ by Genter in Chi's _The Nature of Expertise_ for a good discussion). >day or two.

I have observed very similar problems with at least two different
kinds of terminals. In my case, the terminal would choke if I typed
the word "printf" too quickly. This is a bummer if you are a C
programmer.
These were dumb terminals, not computers. They don't contain much. My
suspicion is that the keyboard scanning chip is scanning the keyboard
matrix too slowly. This scanning frequency probably is a tradeoff
between getting the problem we are discussing and getting key bounces.
The layout of the keyboard will determine which combinations are
poisonous.
If you are adventurous, there might be ways to speed the scanning rate
up by a hardware mod, at least for dumb terminals. Maybe not for Mac's.

The problem seems to be typing "to" (not "sto") on ADB keyboards. It only happens to me on our locally developed terminal emulator and email program, so at first I thought it was the programs; when I talked to one of the developers of the programs, he said it happens to him in other text-entry situations, as well. (Personally, I've never had in happen in a word processor or anything else.) In my case, the problem is that I cannot type a space after the word "to" sometimes; I have to type one letter (which does not appear), then everything is normal. So, if I typed "stop" and the problem came up, I would not get the "p", but the space after would be fine. If I tried to type (why is this the first "sto*" word in my head? =) "stoli", I would get "stoi". Again, this only comes up occasionally-- about once every few hours of typing. I've asked the net for a response to this question before, and never got any. Please post anything you can find out. Ciao, Danno -- || Daniel McKinnon ||Ho! Ha ha! Guard! Turn! Parry! Dodge! Spin!

I believe that my problem is more embarrassing than these: I have a problem typing the word "shift" in WriteNow. My work requires me to type this often and I have the problem that the f gets left out. I'm convinced that the problem is not with my typing in this case. Patti
