03.008 How should the DIP switches be set on a version 3.03 SpeeDemon board?
This is from the 1-page manual that comes with the card:
For owners without a Bank Switch Language Card in thier Apple, the first
seven DIP switches control the access speed of the following:
switch 1 -- controls -- slot 1
switch 2 -- " -- slot 2
switch 3 -- " -- slot 3
switch 4 -- " -- paddle/joystick port
switch 5 -- " -- slot 5
switch 6 -- " -- slot 6
switch 7 -- " -- slot 7
OFF indicates slot/port is accessed at High Speed.
ON indicates slot/port is to Slow Down for access.
All slots that can be accessed at High Speed and all empty slots should
have the corresponding Dip switch set to "OFF" (this is the non-bank switch
setting).
Special Note about Switch 4:
Switch 4 on the SpeeDemon DIP switch no longer controls the access speed
to slot 4. It now controls how the joystick and paddles are read.
If switch 4 is in the "ON" position, the SpeeDemon will slow down to
normal Apple speed for 50 milliseconds each time the joystick is accessed. This
allows the software to read the joystick or paddles correctly. If switch 4 is
in the "OFF" position, the SpeeDemon will not slow down when they are accessed.
Access to slot 4 is always at SLOW (normal) Apple speed.
Certain programs, such as Appleworks, use the joystick location, even when
the joystick is not in use. If dip switch 4 is set to "ON" then these programs
will not show any speed for some functions, such as calculations and sorts.
Therefor, unless you need youysticks for your applications, switch 4 should be
set in the "OFF" position.
If you have a Bank Switch Card (extended 80-col card, Ramworks II, Titan
Saturn 128k card, excetera..) set switch 8 to the "ON" position.
Bank Switch Language Card Location:
Dip Switches 1-3 encode the location of your Bank switch language card. Use
the following table to find the appropriate setting for your machine:
Dip Switch Bank Switch Card Location
1 2 3 Slot #
--- --- --- ------
off off off 0
off off on 1
off on off 2
off on on 3
on off off 4
on off on 5
on on off 6
on on on 7
If you have two bank switch cards in your system, one must reside in slot 0.
The other must be in the slot selected by DIP switches 1-3 above.
Special Note: Because the first three switches are used to encode the
location of the Bank Switch Language Card, you can no longer control the speed
of all the slots. Specifically you can not control slots 1,3, or 6. These
slots woll now always run Fast except for slot 6 which will always run Slow.
Special Note: The slot that the SpeeDemon card resides in should be set to
the "Off" position
