There are only 2 jumpers on the Micro-KIM but they play a critical role in the operation of the Micro-KIM. If
the jumpers are not selected properly, your Micro-KIM will not function properly, if at all.
JP1 is located directly below the 40 pin expansion header on the left edge of the board. This jumper enables the
onboard memory decoding. This feature is installed to give KIM-1 compatibility to enabling memory decoding
onboard. Future expansion boards will need to enable and disable the onboard memory as needed. Keep this
jumper block on at all times unless an expansion board is installed requiring the removal of this block.
If this jumper is removed without some external decoding in place, the Micro-KIM cannot access the onboard
memory and thus it will not function.
JP2 is located above the Micro-KIM logo on the right side of the board. This jumper is the selector between the
onboard display/keypad and the RS232 interface when in the monitor mode. It does not mean that the keypad
and display will not work when running a program. It only applies to input and output while in the system
monitor.
If this jumper is off while the Micro-KIM is in use, all monitor I/O is handled on the keypad and 6 digit display.
If this jumper is on while the Micro-KIM is in use, all monitor I/O is deferred to the RS232 serial port.
