George, you're splitting hairs here. The chip that he's talking about is obviously the EPROM, I realize that some "chip" has to contain the volatile memory. Should we mention that it's a CMOS OTP PROM as well? 
My point was, and still is, that there is no damage to the module, and it can be reset to work with the original chip. Most people think of the "chip" as the PROM chip that contains the sound programming for the PS/1 module. Yes, I realize it takes a special chip to fix the deselect issue, again that is an option available to an MTH tech, as you well know.
