DIP Switches
– All OFF (UP) by default
Switch 1 ON (DOWN) = On an Apple II/II+, use lowercase letters in CFFA3000 menus. Turn this
switch on only if your II/II+ has a lowercase chip installed.
Switch 2 ON (DOWN) = Disable the use of MouseText characters in CFFA3000 menus even on
machines where they are available.
Switch 3 ON (DOWN) = Detailed debug logging.
Switch 4 ON (DOWN) = Host machine is an Apple ///. Since the Apple /// also requires switch 7
to be on/down, switch 4 on/down tells the CFFA3000 to use the 6502 firmware instead of the
65816 firmware.
Switch 6 ON (DOWN) = Power-on self tests: Blink the LEDs in sequence, test 128K SRAM and
8K DPRAM. Then it either blinks an error code on the red LED, or it lights a green LED and waits
for you to turn the switch off before proceeding.
Switch 7 ON (DOWN) = Host machine is a II
GS
or an Apple ///; OFF/UP is not
Switch 8 ON (DOWN) = At power on initiates firmware upgrade (looks for CFFA.bin and/or
CFFA.xsv file on FAT-formatted/MBR CF card only).

Four Small Green LEDs

Meaning
D0
Blinks when reading or writing virtual Disk II
controller. Also blinks while the virtual motor is on.
D1

D2
Blinks when reading or writing the USB flash device.
D3
Blinks when reading or writing the CF card.
There are also patterns that you will see on these LEDs that have special meaning:
*-*- / -*-*
Even/Odd animation at power-up (longer dance if the AVR restarts for some
other reason, like after a firmware upgrade)
*--* / -**-
In/Out animation while the Apple II is being in Reset
Repeated left-to-right animation while waiting for a USB device to be ready
