Attached is one.
The plugs I read the other day all start with 0x1f 0xff, or 0x07 0xff.
This one has a leading 0x00.
The serial number field is consistently 10 characters, and there are
four characters after that before the end of the ROM.
The length of this file is 8908 bytes, but an actual ROM dump is 8192.
I suggest you trim one leading byte and 715 trailing bytes from this
file to see if you get a code plug the radio will eat.
