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!
