So I'm back to hacking on RSX-11M-Plus again, this time in a more
leisurely fashion, and under simh on a laptop since I'm still stuck in
bed with the "Primus Plague" that I caught while at VCF.
I'm trying to install C and F77 from .tpc files in the trailing-edge
archive, and I'm failing miserably. I've attached them to tq0 and have
tried every possible combination of FORMAT=TPC/FORMAT=SIMH, use of
mtcvt23, etc and cannot get past "tape label error on MU0:" from
autoins.cmd.
Doing this under RSTS/E is a breeze, and I expected it to be even
easier under RSX.
I assume I'm not the first person to hit this problem. Before I dig
deeper and spend a lot of time, does anyone know what's going on?

I probably say this every time this comes up: I've heard the point made
that the DEUNA draws too much power to live in a KS10's BA11K along with
the usual mess of stuff. I haven't checked the math but it certainly
wouldn't hurt to make it a DELUA instead, for that reason alone.
At one point I got a minimal start on writing a DELUA driver for ITS, but
it's on my ITS RM80 that may or may not still work.

OK I had PA and PB reversed, but, exactly. I don't know if that means
PA/PB had a slightly different meaning in the early days when the parity
controller was outboard of the core stacks (in that case I'd think you
couldn't mix old and new hardware, which doesn't seem to be a problem),
or else they changed the spec before the hardware hit the streets and
everything is fine (which sounds more like it).

Well, my point is that if it's true that PB is now asserted only on an error
(vs. both being asserted or not depending on the parity of that byte),
then if it *never* gets asserted, everything's fine. Accesses to CSR space
certainly don't check parity so it seems that nothing bad happens if you
don't assert these pins. And I'm thinking the DEUNA/DELUA would stop with
a parity error if it found PB asserted when reading memory with DMA, which
is a good reason to make sure the data structures and buffers you give it
never have the 17th/18th bits set, but otherwise, no sweat. You're giving up
parity checking but the KS10 MMC/MMAs already do ECC and I don't think they
need Unibus masters to be in charge of noticing flaky RAM.

All,
For those who did not attend VCF East you missed a great time! On
Saturday, the keynote speaker was none other than Brian Kernighan. You
really missed a treat - right Dave!
Next year, I plan to bring even more stuff (not nearly as much as Dave
did) but more than this year. Dave's island of equipment included the
following:
PDP-8
PDP-11/34
PDP-11/44
DECserver-200
multiple terminals
I'm sure I have forgotten something...
I added:
VAXstation 4000/60
DEChub-90 backplane with a DECserver-90TL and a 16-port DEChub
VT320
a gateway (actually bridge) machine to connect to HECnet only the link
was pathetic
Brian (aka VAXman) added:
VAXstation 4000/30 (aka VLC)
In addition to the "island" Dave had other "exhibits" that I will defer
to Dave for discussion.
Next year we NEED more stuff! This is the official challenge to anyone
on the East coast. We want to see many more of you. If is is DEC it is
needed.
I would also like to personally add my thanks to Dave and Brian for
making this such a treat. Dave is nuts (in a good way) and very
generous. Brian was there for me when my brain could not content with
the sheer volume of noise - helping me to configure the DECservers and
dealing with my fat fingering the keyboard and the license management
facility (LMF). For a while we were Frick and Frack but we managed to
get it together. Thanks guys!

Peter,
How exactly do I BOOT the SC-40 from tape? You're the only onw who knows.
;)
I have a compatible HVD tape drive and a properly-written tape...now I
just need to know how to boot it.

Hello,
I've been attempting to (likely incorrectly) get the DEUNA emulation
working in SIMH's KS10 simulator.
Current status:
* Exists
* Has an address
* Has a vector
* Can be enabled
* Can attach to host interface
...and that's as far as I've gotten. Currently having issues getting
TOPS-10 to successfully link for KS10 with ethernet support. Anyone have
a pre-genned MONITOR executable?
