You may have finished by now but since I have done that reasonably recently I though I would document what I did/found. Probably the best way was the serial already discussed since you can start it running and let it run without needing to interact. I used kermit. Copy here http://unixpc.taronga.com/csvax/ Kermit setting I used on Linux set line /dev/ttyUSB2 set speed 9600 set send packet-length 1000 set file names literal SET CARRIER-WATCH OFF kermit settings I used on 3b1 set window 3 set receive packet-length 1000 set file names literal set file type binary I had enabled login on the serial port and had logged in so didn't need the set line. You have the floppy drive. The normal 3b1 format is 8 or 10 sectors but it can with the proper software read & write DOS disks. Later versions of the OS came with msdos command to read floppies and md_write and md_format. You probably want to use them to install mtools which are nicer for using msdos floppies. Binaries in above directory. /dev/fp021 is floppy first partition, /dev/fp020 is full disk Also found this page on transfering files that gives another method. https://rhodesmill.org/brandon/notes/unixpc/transfer.html If you have a floppy or hard drive image such as from my emulator there are tools to work with them. https://github.com/dgesswein/s4-3b1-pc7300 Since mounting was done as Linux kernel driver its going to be work to get it to build on current Linux. I have a fedora core 20 system I keep around that the driver works with. > It does have an AUI Ethernet port on the back, but doesn't appear to have > TCP/IP installed.
