Commodore 64 : XUM1541 interface for connecting a 1541 to a PC

XUM1541 Interface

XUM1541 Interface to connect a Commodore Diskdrive to the PC.

There are several ways to get data from a PC to a Commodore 64 (and vice versa).
Most are cumbersome or unreliable and are not easy to use.
The XUM1541 changes that, with this interface it is possible to connect your old 1541, 1571 or 1581 to the PC.
That way you connect an old Serial (IEC) commodore device to the PC via a USB connection.

What do you use the XUM1541 Interface for :

With the XUM1541 it is possible to make images of existing diskettes that you read on the Commodore Diskdrive connected to the PC.
In this way you can easily archive your diskettes and once converted you can use them again to use them on the Commiodore 64 via a modern Disk emulator such as the SD2IEC or the Pi1541

It is also possible in this way to write back digital disk images (*.d64, ..) to physical diskettes on the Commodore Diskdrive.
These diskettes can then be used directly for working with a physical disk drive on your Commodore 64.
