    I've had the following problem on my 1987 (vintage) Mac II:

Upon initial power up, about 1/2 the time the Mac doesn't seem to recognize 
the keyboard. I start up in MultiFinder with a few startup apps and once it
boots all the way up no characters can be entered from the keyboard.
If I reboot without power cycling (Restart from the Finder menu), it almost
always comes up OK the second time. 
	The other 1/2 of the time upon cold power up, it comes up OK.

	I haven't really done too much to figure out the problem. I haven't
reinstalled the system, removed inits, etc. It sure seems unlikely to me
that it is a software problem but is more likely a hardware problem. I
have fiddled with the ADB cables, etc. in order to see if that is the problem.
One interesting bit of information is that one time when the system was in
the state that it wouldn't recognize the keyboard I pulled up keycaps and
found that the system thought the command key was being held down. Typing
a letter from the keyboard to attempt to use a command key equivalent did
NOT work. I have never seen that particular state any other time, most
of the time the system didn't think any keys were down when I pulled down
keycaps.
	I'm sure there are plenty of debugging things I could do: borrow
a keyboard from work, etc. etc. I just thought someone else might have
seen the problem and know a fix.
