|Getting a Mac II to output interlaced at NTSC frame rates is purely a

Yea, and you are going to do that in SOFTWARE, right?  You seem to have
missed Leo's point.  To convert your "data" (not signal, see later) to
composite you need a piece of HARDWARE for the Mac II, and currently
that will cost you BIG BUCKS while on the Amiga it comes for FREE.

|The signal is overscanned and good enough to record on a VCR.
     ^^^^^^
A "signal" is NOT a piece of software.  A signal is a hardware concept.

Good luck with recording on your VCR with your software composite Mac II :-)
