When will CCS64 support connection to a real 1541 drive?
Probably never as there exists very good tools for transferring the data on 1541 disks to system independent file formats (like .D64). As I see it the main benefit of using a real 1541 disk drive connected to the emulator would be to use copy-protected software that uses fast-loaders and/or special formatting that the transferring tools can not handle. But as I am pretty shure that it is theoretically impossible to get the connection 100% compatible so that it will support all kind of fast-loaders, I think it is not worth to implement a half support. The support that should be possible is the 1541 normal loading protocol and perhaps some special selected fast-loaders. To understand the problem you have to consider that the 1541 is not just an ordinary device with a specified communication protocol. In fact it is a complete computer of its own and can therefore be re-programmed to send signals in any way and in any speed wanted, and mostly with very little or none handshaking control (c
