Thanks David, and everyone else for helping me with getting these files off. Starting on Friday I hooked up a serial cable and null modem to my laptop PC, got getty running, and logged into this 7300 as install.

Escalated to root and went over to his directory. The big problem is the system did not have kermit but it *did* come with an XModem like program that I could hook up to with a simple Xmodem protocol on the PC. Uploaded Kermit, and sure enough it works...

From there it was a matter of copying the files and . files in his home directory, then tarring and compressing the big directories. This let me know just how far we had come: It would take 10+ minutes to compress a 6mb tar file, but when I decompressed it on my Mac Mini it would take well under a second. We have come a long way...

After moving all the files and directories I patted the computer on the top of the monitor and said to it "Well Done, though good and faithful servant" then did a rm -r on the rdd directory. Now I can put it up for sale and give the money to his mom.

Today I went over to her house with a 40 page folder of some of his writings. Bob was among other things an amazing author, and the items on this computer spanned his life from 1986 to about 1993. She was very happy to see his writings and poems, in a way it gave her a chance to get to know him again even after all these years....

Now I have a big crate with "Convergent technologies" sitting in my truck, I'll have to figure that one out next. Also more Perq manuals and floppy disks.

It's never a dull moment. But it's nice I was able to use my forensics skills to bring an old friend to life again...

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

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 

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 
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.
