Having had success with ADTPro in audio mode (Apple II cassette IN/OUT transfers) I'm eagerly awaiting a USB to serial adapter (FTDI chipset) for transferring more of my 5.25" II+ floppy disks over to my Mac. I intend to use them with an emulator of some kind (haven't decided on any in particular but have played around with Virtual ][ in trial mode but I know there are others as well.
Many of my disks contain files I've made myself which would be nice to use with my Mac within current software. These are graphic images, MIDI files, text documents (Wordstar CP/M) and so on. I see that Retrofloppy offers a service for this sort of thing, and from touching the subject before I believe I need to use FTP transfers between the two platforms for this, but is there an FAQ/step-by-step guide for this somewhere? I'm hoping that once I get the USB to serial interface, and transfer a terminal program over to the II+ I should be able to do the transfers.
