If it's a T3100 (8Mhz), the floppy drive is 720k - if it's a T3100E
(12Mhz), the floppy drive should be 1.44M.

If it boots to DOS, or you can get to a DOS prompt (ALT-F4/Enter in
Win 3.x), then you should be able to communicate with the DOS prompt
via a terminal on the serial port: CTTY COM1
[I recall that the default speed is somewhat low, but it won't really
 matter as long as you can figure out what it is with your terminal
 emulator - if you like you can blind-type a MODE command first to set
 the serial parameters]

Once you get to a DOS prompt, you can format diskettes and copy files
to them - Don't try to run any non-command-line software!

Another option would be to use INTERLNK - you can "blind type" the
MODE and COPY CON: commands required for RCOPY and then run INTERSVR,
or you can prepare a DOS boot disk that runs INTERSVR in the AUTOEXEC
and boot the machine from floppy.

You could also use the boot disk approach to get LAPLINK running on
the machine etc...

As long as the machine is still actually running, it shouldn't be that
hard to get the data off - Enjoy the LSI-11.
