FDFA

POLLKB
Waits for the user to press a key, then returns.  The ASCII code for the key pressed is stored at address 0001

FE73 OUTPCR
Outputs a CR to the display
FE75 OPCHR
Outputs the character in the accumulator to the display
FF0B HEXPNT
Outputs the accumulator to the display as a pair of hex digits
FF28 HEXPCK
Reads hex characters from the current cursor line and converts them into two 8-bit binary values stored in addresses 0013 and 0014.  Set IY to the offset of the first character to convert (0=start of line).  Conversion stops when a non-hex character is found.  On exit, Z is clear if the terminating character was the cursor and V is set if there were one or more characters converted.
