Not implementing it with bankswitching, but writing to a trigger location the
way most bankswitching schemes work. Isn't that also how Pitfall 2 handled
its music? This ought to be even simpler as you're talking about writing a
single byte indicating which sample to play next (assuming that Vectrex thing
works in a similar manner to the Odyssey2 Voice.) The speech synth would
have to have its own speaker or other means of audio output, but so would the
Vectrex one.
I wonder if anyone's ever disassembled Spike for the Vectrex to see how they
implemented their very passable software speech synth. Of course a 1.6MHz
6809 where you can make your kernel take as long or short as you want is
probably more amenable to that kind of thing than the 2600.
