Macro Keys
One of the best features of this interface is it's ability to use
the extra keys on the AT keyboard as macro keys. A pre-
recorded sequence of keystrokes can be associated with
each macro key. The sequence is re-played whenever the
key is hit. This is especially useful for commonly used
commands, and for defining application specific key
combinations for the named keys such as
INSERT
and
PAGE
UP
.
T
he macro sequences are re-definable at any time
through the keyboard, and are saved indefinitely. Each of the
16 available macro keys can have up to 32 keystrokes
stored. The sequence is stored exactly as typed, including
overlapping keystrokes (one key held down while another is
pressed).
The timing of keystrokes is not stored, so the keys are
replayed at a fixed rate regardless of the delay between
keystrokes when recorded. The macro keys are F1 through
F10
,
and the keys
INSERT
,
DELETE
,
HOME
,
END
,
PAGE UP
,
and
PAGE DOWN
.
To define a macro key, perform the following steps:
1. Press shift macrokey.
2. Type the sequence of characters you want recorded.
3. Press shift macrokey again.
The macro keys pressed in the first and third steps must
match for the sequence to be stored (as a guard against
accidentally re-defining a macro). You cannot use macro key
while recording another macro. An attempt to do so will stop

Installation
The following is a step by step instruction guide on how to
install your new AT Keyboard Interface
board into your
system. Before you start, make sure that you have the AC
power plug removed from the wall. If a multi-pack is present,
make sure that the power is removed from it and it removed
from the CoCo’s cartridge port. Make sure that you have a
static free area when performing this installation.
Required Tools
1. Phillips screwdriver
The interface plugs right into the CoCo's mylar keyboard
connector.
1. Remove all screws on the bottom of the computer.
Note that the shorter screws are removed from the
front of the computer by the keyboard.
2. Remove the keyboard from it’s mounting position and
motherboard connection.
3. Plug the interface into the mylar keyboard connector
so that it is closest to the front of the CoCo's case.
Inspect the pins to ensure they are aligned with the
contacts on the mylar connector. The AT keyboard
connector’s jack will be face the CoCo’s cartridge
port.
