[Kantronics] KPC-9612 Firmware...

[KBØNLY]

If you open it up from the front, remove the two front panel screws, then 
remove the front panel, then there might be a screw holding the voltage 
regulator to the case depending on which revision you have.  You should now 
be able to slide the PCB out of the case to look at it.

There is a couple socketed chips on the board.  One should have the 
Kantronics firmware version and other info printed on a label on top of it. 
You will need a sharp knife or a small flat screwdriver to peel that label 
back and see if it has the small window on the top of the chip to erase it. 
Before you peel or scrape off that label though make a note of which version 
it is, so i can make a backup copy to fall back on if necessary.

All you need is one 27C1001 for the firmware.  If you end up ordering a chip 
from Mouser or Digi-Key make sure you get the DIP package as they do sell a 
PLCC and surface mount version as well.
