Subject: Kaypro II needs help!

Hello All --
Any Kaypro II users out there??  I've got one that acts like someone's
leaning on the three key.  When I power it on, the "A>" prompt comes up,
but then a line and a half of threes follows.  CP/M tries to interpret
that as a command line, echoes it back (followed by a "?"), and then the
whole thing starts again.  It does this with the keyboard disconnected
also.  Once I got CP/M to come up clean, but then the first key I pressed
filled the screen ("D" from "dir").  I've got no schematic, so I haven't
much of a clue where to start to look.  Anybody seen this before??  Does
the keyboard (serial) go in via a PIO, SIO, or a TTL 8-bit serial shift
register (74LS164 ??) ?  Any comments would be appreciated.
