Modes of operation
The 1541 Ultimate has two possible modes of operation.
Cartridge mode
In this mode the 1541 Ultimate is inserted into the cartridge port of your Commodore.
This is probably the most common way to use the board. To have access to the 1541
Ultimate’ emulated drives, you need to connect an IEC cable from your Commodore
computer to the 1541 Ultimate’ IEC port, just as you would connect a real 1541 drive. If
you don’t connect the cable, you still have the cartridge based functions at your disposal.
I advise to disable the direct SD-IEC support, since in this mode you can browse the SD
card through the middle freeze button, and it will cause less problems with other software
and hardware.
The keyboard shortcuts supported by the 1541 Ultimate’ User Interface in cartridge mode
are:
CRSR UP/DOWN Move the cursor up/down
CRSR LEFT/DEL Leave a (sub)directory or D64 image
CRSR RIGHT Enter a (sub)directory or D64 image
/ Go to the root directory of the SD card
RETURN Select a directory entry, load a program, or mount a D64
image
F1 Page up
F7 Page down
F3 Mount disk, and run a program using DMA
F2 Enter the 1541 Ultimate’ Setup menu
SHIFT+C Create an empty D64 image on the SD Card. Please note that
the first D64 image created after a reset (or power-up) can take
several seconds to complete. Each subsequently created D64
should take less time.
SHIFT+D Create a directory on the SD Card
INST (SHIFT+DEL) Delete the selected entry
