I have here a PDP-11 which was used in a X-ray-"defractometer".
There was no Boot-disks or documentation.

	3HE-19"-case (with a label VAXstation 3200) with an on/off-switch
		and 6 buttons.
	3,5"-HDD (probably ST-506-type)
		Fujitsu   Model M2227D2
		Type B03B-4815-B104A#B
	On the side to the disk/floppy there are unused connectors:
		Fixed Disk 0 (2 con.)
		Fixed Disk 1 (2 con.)
		Removable Disk 1&2 (1 con.)
	It has 3 modules:
		quad-size from Mentec with 4 connectors (serial ports)
		quad-size from MDB with 4 unused connectors
		dual-size from Dilog (connected to disk and floppy)

	It is installed RT-11FB V5.04D.
	The output from resorc/a is:

RT-11FB (S) V05.04 D
Booted from DU0:RT11FB

USR   is set SWAP
EXIT  is set SWAP
KMON  is set NOIND
TT    is set QUIET
SL    is set OFF
EDIT  is set EDIT
KMON nesting depth is 3

LD0 is  DU0:USER.DSK[50068.]  = DK 
LD4 is  DU0:USER.DSK[50068.]  
LD7 is  DU0:PW.DSK[3000.]  

I got somehow a M70>-Prompt (after a @-Prompt) and booted it with DU<Return>.

Can I make somehow a bootable floppy-backup?
Is it supported by V7 or another UNIX?
How big is the harddisk?
What device/size is the floppy? DK? 
Is it possible to read/write these floppies with a PC?
Is it possible to make UNIX-boot/install-floppies with an emulator
and install with the UNIX on this PDP-11?
What did I forget to ask?
