There is also a jumper pair near the bottom middle of the card. This is the
Speed Jumper. Jumper it if you want 'demon to slow down for I/O accesses to
Slots 4 & 5. (The 'demon always slows for Slot 6 I/O ($C0E0 - $C0EF.)
According to the "Manual" (a folded card), pressing PDL-1 (Closed-Apple on
a IIe) upon power-up will engage a self-test. Pressing ESC at power-up will turn
OFF the card and allow running at normal speed. To turn OFF the card later on,
do a POKE (49152+256*S) where S= Slot # of the slot the card is in; then, press
RESET.
You can put the 'demon into any Slot; but, if you put it in Slot 0 (Slot 3
in a IIe), the card will not respond to any KB shut-off commands.

006- How does the SpeeDemon rate as an accelerator for
II+ and IIe Apples?
In terms of raw performance (once you arrange for cooling), SpeeDemon may
be the best of the 4MHz accelerators for early II's. I've never noticed any
compatibility problems and the approx. X3.5 speed increase puts real 'snap' into
your machine's response. (Besides, it's great for games like Elite!)

007- My SpeeDemon accelerator board seems to run hot in
my II+. Is this normal? Should I add cooling?
Indeed, the 'demon is a power gobbler-- roughly 1.5A as I recall-- and some
of the IC's run hot. When the board bombed after one long session, we cut out a
square section on the back of the II+ and added a mini-fan, just to blow air
across the 'Demon board. This ended the heat problem.

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
