I am putting together a PDP-11/23 and have a working RSX-11M 4.4 OS running
in simh while I wait for a few parts. I want DECnet as well. I have the 4.7
kit and have done a netgen, but I can't install it because I don't have the
CEXPAR partition in my system image. I have gone over the VMR command in
the manual a few times and tried various things to try and create the
partition in my image, but have not been successful. I assume (from looking
in the manuals) that I either need to create that partition in my image, or
make room for it?
The netgen process has the defaults of 113500 as the base and 4300 as the
size. VMR complains about 'non-existing memory' for the base and if I try
the wild card I get 'alignment error'.
I have 512KW of memory that I plan to use in the real machine, so simh is
configured with that as well.
Any pointers would be greatly appreciated.

I will soon receive an ASR-33 and I will need roll paper, 1" rolled
(preferably oiled) paper tape and a ribbon or two.
Please DM me if you have any to spare.
Thank you,

Paper is easy enough - its a standard telex roll and they're still made
and sold. We used to have it in two grades in England - high quality
white for special occasions (use a new ribbon and clean the head first
and it almost looks good), and bog roll. If you know, you know ;-) Just
make sure you don't order the thermal version by mistake.
Telex ribbons are still made and sold in the usual places too. You can
fit a standard typewrite ribbon but of course they're normally
black/red. Pretty effect but probably not what you're after.
Paper tape is more of a problem but GNT still makes 1" (or did last time
I bought some). You don't say where you are (no one ever does on this
list) but they're in England. It's still used for CNC machines, amongst
other things. Getting the five-hole is more of a problem IME.
Regards, Frank.

Not relevant for you but relatedly, I just bought silent 700 thermal paper.
Won't be available forever.
https://www.mrpaper.co.uk/catalogsearch/result/?q=TH216-15
This is the same as fax paper but apparently the fax paper rolls hold more
paper and won't fit the roll holder on the silent 700.

Oiled paper is preferred if you can get it, but at this point it would be
expensive surplus. If you get non-oiled paper I don’t know if there would
be additional occasional mechanism maintenance needed. I guess take what
you can get.

If you get non-oiled paper I don’t know if there
would
be additional occasional mechanism maintenance needed. I guess take what
you can get.
Not only will there be more stoppages, you'll wear out the punch pins faster. Oiled
paper is pretty well a hard requirement.
You can of course *read* non-oiled tape without damage.

"This is the same as fax paper but apparently the fax paper rolls hold more

If you need a roll adaptor, or a core for re-rolling the paper on, I can
CAD that up, post to printables.com and/or 3D print that for you.

I seem to remember that you can use dry paper after soaking it in oil.
Put a very thin layer of light oil on a plate and let the paper roll soak in it.
