  Hi all --
 I finally tracked down the EIS option for my 11/40 and I have it up and
 running nicely (Ultrix-11 ATM, but I'll be playing with other stuff).
 Right now I only have a 4-slot DD11 backplane for SPC/MUD boards and I'd
 like a bit more space for expansion.
 I have a few DD11-DK backplanes but without modifying the cabling it won't
 work in a BA11-F chassis.  If anyone has a DD11-DF they'd be up for
 trading
 for the -DK variant (or for something else) please drop me a line.
 Thanks!

 Josh,
 Did you pull the Ultrix-11 from an image or make it yourself.  I'd love to
 get a copy of this if you're able to image and post to the web, and I am
 sure simH folks could use this too.
 
I built it from the tape images on TUHS on SIMH and wrote it out to a real
disk (cheated, since I'm fortunate enough to have a UNIBUS SCSI controller
to play with).  I'm happy to share it out, though it's not too hard to do
manually -- there's a writeup at
https://minnie.tuhs.org/Archive/Distributions/DEC/Ultrix-11/Fred-Ultrix3/se…
that covers the basics.
  Glad to to hear you were able to get this running with
the EIS, I was
 unsure if it was possible.  How much RAM do you have?
 
I have 128KW of MOS memory in the system (wish I had core, but I'll take
what I can get).  Ultrix runs fine, but it's tight and the lack of separate
I+D spaces means some programs won't fit (vi, for example).  I did manage
to build a kernel with TCP/IP and Ethernet included, but I need the larger
backplane in order to install the Ethernet controller to test it :).
 I will check to see if I have the backplane.
 
Thanks!
