It's an
HD6303X. I can look up all the letters (things like the clock
rating) if you need them, but that should be enough. In any case, writing
a disassembler is not going to take me too long if I need to do it.
I don't have a Hitachi data book handy, although I know there are some
"somewhere" in the workshop - I'm guessing that this is a second-source
of a Motorola 6803, which is essentially a ROMless 6801, which is a
slightly enhanced 6800.
