Ok, it's me again with another RSX-11M question.
I have a nearly complete set in PDF form for 4.2. But I am running 4.8.
Is 4.2 close enough or does anyone have a set for 4.8 or maybe even 4.6?
In searching around on the 'net I have found a release notes doc for 4.8
but that's it.
Thanks!

Hi Mark,
Wow! Thank you for this info! I built the CLR command and it works
flawlessly. I need to read up on Macro11.
I will definitely check out MCE. I tried something like that a while back
under M+, don't know if it was MCE or another one I had found.
Thanks!

So, I may just be spoiled from using RSX11M-PLUS and now expect too much
from the RSX11M OS. But it seems to me the CLS command would be a
nice-to-have, but I am not able to find anything about it. So did that not
exist for RSX11M? How does one clear the screen in that environment?

Hi Mike,
Honestly, I don't know. How wide is the cartridge? I have an 88MB cartridge

Hello to the group,
I have been banging my head against a PDP-11/23 where I have an RQDX3 I'm
trying to get to work. Actually, I have two RQDX3's but only one at a time.
It is configured to the factory CSR, 172150, and it has the latest
microcode on it. When I run the XXDP ZRQCH0 formatter I get t

It is still a 'good to have' for those running real PDP-11 machines without
I/D support, like the 11/23 and 11.23+.
The TCP/IP stack Johnny has written works great on the machines (emulated
or real) that do support I/D space.

Ooo! Awesome! It turns out my setup is missing a lot of things so

Well, I learned that not all drives that look like ST-506, are... Turns out
the drive I was going to use is a Micropolis 1355, which is an ESDI drive.
So it won't work with the RQDX3.
I guess that drive goes back on the shelf until something else comes along.

Hmm, not sure why yet, but I'm not able to get vtserver to work. I have
entered the bootcode manually in ODT, and I have had vtserver send it.
It looks like it loads the code and then reads one record but then hangs.

handled

Thank you all for the tips and pointers. I like the idea of pulling the

I found that out the hard way recently when I acquired my AS/400 and the

And of course I had recently gotten rid of my old 10Mb/s hub I had been
