As previously posted, the H89 which Joe Rigdon kindly gave me has a problem
with the keyboard input: sometimes it works properly, but sometimes double
characters or wrong characters are produced. This behavior can change
while using the machine -- one moment it's okay, the next moment I get
wrong or double characters.
Anyone have a set of docs they can reproduce for me? Or any experience
with the keyboard controller circuitry on this machine?
TIA --
Glen
