Using OpenCBM and related software
Here are some documents on how to use OpenCBM. All the commands are supported by the
ZoomFloppy. Do not download the binaries for OpenCBM 0.4.x as they do not support the
ZoomFloppy.

There are several GUIs for OpenCBM.

You can get nibtools from the C64 Preservation website.

Adding a parallel port to your drive
For copying protected software with nibtools or the highest speed transfers, adding a parallel port
to your drive is a must. These cables, originally designed for SpeedDOS and Burst Nibbler,
connect the VIA or CIA chip in your 1541 or 1571 drive to a 15-pin D-SUB female connector,
aka game port.
The best way to attach the cable is the solderless approach. You remove the VIA in your drive,
plug in a socket, and then plug the VIA into the socket. The D-SUB port is then attached to the
case or routed out the back. Peter Schepers sells these cables (see section “Disk Drive Parallel
Ports & Cables”, solderless options).

Then you need a cable to connect the drive to the ZoomFloppy. The easiest route is to get a 15-
pin D-SUB male-to-female cable. If you want to use your new parallel port with a C64 also, you
should get the “C64 user port parallel cable”, also available from the above site. It plugs into the
card edge connector on the ZoomFloppy.
