the speaker and paddle circuits are accessed at high speed
if the card is in fast mode.  the joystick circuits don't work
the way they should (at least, the monitor routines to access
the joystick dont work)   you move joystick hard left, and start
moving it to hard right.  the monitor routines cycle from
0 to 255 as paddle reading, and then reset to zero and cycle
back up to 255 as you move the stick.  It thinks that the
stick is at all positions about 3 times as you move it.

hard left 0-255 0-255 0-255 hard right

when it should do:

hardleft 0-255 hard right

the speaker gets accessed way too fast and you get
some interesting pitches, buzz's and clicks.

the zip chip slows down for paddles and speaker
as an option if I remember correctly.  transwarp
does not.

I thinnk that the transwarp II would allow you to slow
down for these areas of hardware.
