AIM 65 lives

If I duplicated a message to cctech, my apologies;
what I meant to send was:

I just confirmed that my recollection was
correct and that the AIM65's TTY I/O is
effectively RS-232 compatible. I connected 
an AIM65 to 3 different computers and they 
all communicated just as is, i.e. without 
any level conversion. Needless to say this
assumes that the distance is fairly short.

Just connect ground, J1-Y and J1-U to RS-232
ground, TX data & RX data respectively and if
your RS-232 port is like mine, away you go. 
If you have trouble with autobaud, set the baud 
rate manually at A417/18 before switching to TTY.
(Set the terminal/computer to 7 bits).

Unfortunately the KIM-1 doesn't seem to have
an RS-232 compatible serial input, so you'll
have to add a limiting resistor & two clamping
diodes and connect to U15-12 as the AIM does.
