Hi all --
I'm finally turning my attention back to my 11/40 (which I started working
on 7 years ago and never quite got around to finishing -- I've learned a
lot since then and I'm hoping to be able to debug it properly now).
My ultimate goal is to run V6 or V7 UNIX on it -- I have the MMU but I'm
looking for an M787 (line-time clock) and M7237 (stack limit register) to
complete the set. I have other DEC stuff for trade, drop me a line...
Thanks!

Just curious, are you aware whether these two are required to boot a RL02
disk or certain versions of RT-11? I have been experiencing difficulties,
I only have the m737 iinstalled in my system.

TTBOMR the stack limit register is not need for Single Job and the
other RT11 OS variants. However a program could overwrite the vector area
and cause an ungraceful shutdown. Make sure the jumpers on the KD11-A are set
correctly for this configuration.
Using an RL02 to boot RT11 should be okay as well.

RT11 will run w/o an LTC.

from an RL02 on my 11/40 my next move is to emulate a
TU58 drive on a 2nd
serial card and run XXDP. I can run BASIC with no problem,
but it seems
like my known working (elsewhere) M7762 RT11 controller card does not wake
up when called by the bootstrap 9312 ROM, etc.

Rt-11 must be configured for the controller that boots it at the CSR and
vector its using
(try the standard addresses/Vector). RT has few needs and will run on a
16K machine
with minimal hardware (console and boot device). I have a 11/2 with
28KW and
DLV11J that boots RT-11FB from TU58 (very slowly but it does!). That's
a tiny 4
slot Qbus machine (BA11VA) and is very minimal.
Also make sure your trying to boot RT11SJ initially as that has the
lowest needs.

To the best of my recollection?.(sorry). I didn't recall and don?t see stack limit
as a requirement
for RT-11 in any release notes I quickly scanned this afternoon. The LSI-11 doesn?t
implement any stack overflow detection and works fine under RT-11.
If BASIC runs, interrupts are working ok. That would support a TU58
as well.
If neither RL11 Controller and/or RL02 drive show activity when you try to boot

from disk there are some other things to investigate.
E.g. Toggle the RL02 Bootstrap if you can,
Check NPR (DMA) Grant jumper wiring on
the Unibus Backplane. If you haven?t already
tried these, these are easy enough to walk through.
