No, the PLUS/4 and C16 were not completely compatible- the C16 lacks the 6551
ACIA built into the +4, and the C16 has only 16K bytes of RAM, not 64K.  The
BASIC version is 3.5, although it does includes most of the DOS commands.

The C16 does not even have a user port.  The joysticks used on the C16/+4 are
the same as usual, but the connectors were little round DIN things.  Adaptors
are easy to build.  The dattasette was different, as was data on the tapes.

Last I heard, some IC parts and manuals were available from Commodore- call
customer support for availability, cost, etc.
