Thank you, Uh Clem (Frank Durda), and you too, SOB (Stan Barber), for
the Model 4 port info.  Checking it out in BASIC was fun; implementing
it in ASM will be boring but useful.  I got everything but sound.

... 18 minutes of silence accidently deleted.....

Is there a noise-maker in the Model 4?  I tried "OUT 144,everything"
following Stan's suggestion that "90H allows you to sound the sound
board" but got no sound.  Am I missing something?  I'd like to have
an audible bell instead of the visible flash I now have.

None of this is in the Model III/4 Cassette (whatever-title) Operation
and BASIC Manual.  The POKE and OUT for double-speed are in there, but
RAM locations and ports are not mentioned for things you control by
sending characters to the screen.

If you have an early cassette model 4, the buzzer was not included.  It 
came with the disk upgrade.
