I know from previous experience on this group that there is at least one 
other person out there that uses a CIT 101 terminal.  So here is the problem.
Recently I managed to find a fin little program that sent a few thousand Beeps
and other nasty control characters.. Instead of just turning the terminal off
and such, I decided to see if I could stop it.. I did.  But apparently it 
killed my keyboard.  I didn't even think this sort of thing was 
possible but apparently it is.   When I test the keyboard now with a 
continuity tester the transmit and ground wires are showing continuity.  
I went down to the place where I bought the terminal and checked out a 
semi-parted out CIT 101 keyboard and it does not show this little 
problem so I know that it is a keyboard problem and not a motherboard 
problem (fingers crossed).

So the question is.. has this ever happend to anyone else and whether it 
has or not, does anyone know what chip might be fried.. I traced it as well 
as I could but couldn't find anything definatvie. The chips that I found 
in there are this.
starting from left to right:
74244, 74374,74373,7407 (twice)
first one that I traced transmit wire too.. is
SN75452BP  J215D2

continuing on..
555 (timer of course)
and finally the one with the big heat sink:
(not TI) F 8127 7805UC

And thaz it.. so what might need to be replaced here? I would love to 
unsolder all my chips and replace them all but I am hoping that there might
be an easier solution.  Currently, I have been forced to turn on my 
PC and use a comm program just to talk to my modem...  You laugh but I have
a PC1 (8088) with 256K of RAM and a Green Screen.. Bleck.  I want my 
terminal back.

Any help would be appreciated.. thanks..
