You know, I think half of these solutions are far, far more complicated than they need to be.
All he needs to do is use the floppy drive, and a program to split files to fit on disks. That's it! It's really not that hard, and won't take too long. It'll be faster than setting up all this other stuff
It amazes me how many vintage computer guys seem to hate floppies. Come on! Floppies are a fact of life when dealing with old computers. Sure, there are problems here and there, but by and large, they're very reliable. Keep your equipment clean, and take care of the disks, and they work just fine.
I even once did a multiple floppy file copy between servers. A botched upgrade on a SQL server had trashed the kernel and it's associated modules. I could get the machine up with a boot CD, but couldn't talk to the network. I had an identical server right next to it, so I could copy it's kernel and module tree. But these are Sun systems (although running Linux), and don't have USB ports, CD burners, etc. And even if they did, the only way I could boot the borked box was from CD, so I couldn't use the CD drive, and the installer's stripped down kernel probably wouldn't have been able to use USB storage. The quick and dirty solution? Floppies. I used tar to make a multi-volume archive onto 3 1/2" floppy disks. I copied about fifteen megs of data this way. Worked perfectly, and was far faster than any other solution my co-workers came up with.
The funny thing was that I only needed two disks. I just wrote the first disk, stuck it in the target machine and started extracting it. When the second disk was done writing, the first disk was done reading, so you swap the disks, starting to extract disk 2 on the target while overwriting the old disk1 with disk3 on the source.
Salute the humble floppy! They are your friends. Take care of them, and they'll take care of you.
