Anyone know the best way to get files off an AT&T

one has a lot of Perq stuff in a directory as well as hilarious things you
can do with RP06 disk platters (ah, when we were young...)
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

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.

If you have a floppy or hard drive image such as from my emulator there are tools to
work with them.

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. Maybe I can install TCP and find my old Synoptics 10bt to
AUI adapter?
Never had access to a machine with Ethernet so can't help.
