[comp.misc] keyboard

steven@lakesys.UUCP (Steven Goodman) (05/24/87)

I own a Compaq DeskPro 386 and have found that the keyboard on my machine
is having troubles when attemting to type the same character twice.  It will
often skip the second character.  Question, any other owners of this machine
having a similar problem?

     The same problem appears on the Compaq Portable III also, except worse.
It will often not keep up with the typist (not very fast one) even when in
DOS (we're talking about a 12-MHz 80286 here).  My feeling is that Compaq 
messed up on their keyboard debounce circuitry.  At first I thought this was
an isolated case, but maybe it's not...=)~wgk

    This sounds like the same problem that the early Compaq had (back when
there was only one Compaq).  The debounce circitry is really screwed up,
not to mention the rest of they keyboard (which is like typing on mashed
potatoes).  My only suggestion is to try and hook up a third-party keyboard.
I've got directions on how to do it to the old Compaq's somewhere, if that
could be any help.
