At this point, the word KIM will display on Hyper Terminal. If it doesn’t, check your cable and your Hyper

Before you begin, make sure Caps Lock is on because the monitor does not recognize lower case letters.
There are only a few simple commands in the TTY monitor. To examine an address, type in the address and
press the space bar. The address will be displayed along with the value of that address. The cursor will move to
the right of the value.
To change the value of the current memory location type in the 2 digit HEX value and type in a period “.” to tell
the monitor to change the value. The monitor will respond by displaying the next address automatically.
To run a program type in the address and press space, next type G and the program will begin from the
currently displayed address.
The TTY monitor also has paper tape functions built in to load and store programs from paper tape. Well,
Hyper Terminal can act like a paper tape machine and this gives a great storage means for your Micro-KIM
programs. This is discussed in detail in chapter 8.
Be sure to read the KIM-1 Users Manual for a more in depth explanation on using the TTY interface. The
interface is different for every PC and may require adjusting of the character delay, line delay to get the right
setting for your machine.
