Greetings:

I do believe I have 1.5 in my ROM Image Library. I also believe that
it is the last Rev. ever done for the 802.

If I recall, there are three (3) ROMS. Two are OS ROM's, the third
is voices / patches. Also, if I recall the Voice ROM has not changed
since the original release around 1.1 / 1.2 or something like that.
