[Kenwood] TS-950SDX EPROM discontinued

[kk2ed at comcast.net]

Thanks to Mike WZ5Q, who graciously pulled the original eprom from his TS-950SDX, we now have an image (BIN) file of the original eprom.  



If anyone is interested in updating their 950SDX's firmware to the latest (last) version , I have a few newly burned (aka programmed) firmware chips for the TS-950SDX at a cost of $25 including shipping via USPS first class mail.

It is accessible just fine.  If it is an eprom, I can read it (and therefore clone it).  Since I am only interested in cloning it, I do not need the original source code or compiling utilities to decipher any embedded info. 

I've successfully done this on other radios in the past.

Same Difference. 
You know what I meant. 
The Data is probably not accessible.
