SD Card disk drive for C-64?

" I am saying don't make a permanent hardware change to a 1541 that does not have the switches unless you really want it to be permanent because there is a software method of assigning drives that is good enough most of the time. BUT if you must make it permanent and you don't have the external switches, consider adding some form of external switch so you don't ever have to open the case again to put it back to the default." Well then, we're having a major agreement. ;-) The device ID switch is the ultimate fix for Commodore drives, and I'm really not sure why CBM didn't incorporate one into the design - at least from the 1540 on upwards. Can't have cost much to add a discretely located access hole (or a knock-out) in the case, along with a 2-place DIP switch for controlling device ID.
