I'm starting to collect some qbus equipment

setup a system around a KDJ11-AA CPU.
My current configuration is:
BA23 enclosure
KDJ11-AA (m8192)
MSV11-QC (m7551 cf)
DZQ11-M (m3106)
RQDX3 (m7555)
TQK50-AA (m7546)
First, will it be possible to boot this configuration? Can I setup to
start the KDJ11 in ODT mode and enter a bootstrap for the RQDX3 by
hand? How long a program would I have to enter?
You could enter this MSCP bootstrap by hand with a dumb terminal in
ODT, but you would probably want to use a terminal program to send it
rather than typing it.

I haven't actually tried that MSCP bootstrap, but I did enter the
TMSCP bootstrap I found there via a terminal program in ODT mode on a
KDJ11-A and it worked fine to boot from a tape.

When I was getting my first PDP-11 put together, before I even had a
VT of any sort, I'd use TELEX.EXE running on my old PC to download
the bootstrap. With the hardware you have here though, I think you
need a DLV11-J 4-SLU board, the first serial port on the DLV11-J is
your console port. You might want to keep your eye out for a 3rd
party disk controller with the bootstrap built in. I used a WQESD/04
for several years before getting a quad-height /73 board. At one
point the WQESD was in my /73 along with an RQDX3 (for RX50), and a
Viking QDT, all it did was boot the SCSI drive on the Viking board.
That was an "interesting" configuration.
I believe the recommended solution is to use a MXV11-B, but then I've
never owned one. That would give you 2 SLU's, a little RAM, and boot
ROMs.
