Well, the 5710 does not contain a real WD177x core. It contains
something like an equivalent to it, as much as needed by the 1571CR.

I do not have much info about the 5710. However, looking into the 1571CR
ROM ($8000-$BFFF) compared to the 1571 ROM (same region), it is obvious
the 5710 has to be programmed very differently from the WD177x.

Regards,
Spiro.
