Well, I looked around and couldn't find anything similar, so here goes. Attached is the firmware dump and some sort of executable that the Yaesu Update program uses. Poking around the file, at the end is the string:
"FTM-350 series USA 1.3 H8S/2268"
preceded by a bunch of padding, so that and the 256k file size makes it a pretty safe bet this is the actual firmware, and not encrypted image that is decrypted by the weird second file.
I've also attached a link to the H8S/2268 product line, but I've never reversed this family, nor do I have the tools to do so (I think.)
So there you have it.
On another note, anyone have a schematic or service manual (not alignment) for this rig?
