 The files

http://minnie.tuhs.org/UnixTree/V7/usr/sys/dev/rl.c
http://minnie.tuhs.org/UnixTree/V7/usr/sys/conf/mkconf.c

don't seem to match - mkconf.c wants to generate references to
rlopen() and rlclose(), which don't exist in that version of rl.
What I'm really looking for is the right version of driver(s) etc. 
 It seems that a version of the rl driver that matches
 mkconf, was never supplied by the bell labs.

 As a workaround delete the rl entry in cdevsw and the line
 "int rlopen,..." from c.c. This will give you a block device of the rl
disk,
...
  but no raw device. 
Hmm... my 7th Edition distribution  /usr/sys/dev/rl.c  certainly *does*
have rlopen() and rlclose().  If you want them, I can send rl.c and the
matching mkconf.c  to you, or to Warren, along with the rl1conf and rl2conf
(for RL01 and RL02 disks) from  /usr/sys/conf/  and any other files needed
(if someone can tell me what might be required -- it's a long long time
since I looked at any of this.   The distribution came for an 11/23 with 2
x RL02, and it also has some special source files for 11/23, 11/34, etc
("small machines") including tests for recovery from segmentation traps in
floating point (which isn't the same on all PDP-11 models), and an RK
driver from the Boston Children's Museum which handles overlapped seeks on
multiple drives.

I'll be away for a couple of days so don't expect a prompt reply, but the
source is online here so I can easily copy a few files when I get back.
