A2RTR will be down tomorrow (Monday) for a couple of hours sometime
between 9AM PDT and 3PM. It's not my doing - PG&E is replacing a
transformer and the power will be off. I have battery backup for some of my
equipment, but not A2RTR. Sorry.
It's also going to have to go down sometime again, maybe next weekend, so
I can replace a disk drive that's failing. I bought two identical drives
and plan to set up a RAID 1 array this time. If anybody has set up a
software RAID on Ubuntu, using the md driver and mdadm, for the system drive
and you have advice, let me know. Espcially if you managed to make both of
the drives bootable.

Recently Al Kossow made available a zip file containing a Micro/PDP-11
installation kit for Unix V7M-11 V1.0 on bitsavers as RX50 disk images.
Tinkering away here in Covid lockdown, I've managed to get this running
under SIMH pdp11 emulating an almost historically accurate PDP-11/23 plus.
I've placed the SIMH initialisation file, a couple of RD51 disk images and
an "installation recipe" for making these disks on GitHub at -
https://github.com/agn453/V7M-11
While I mainly had exposure to later versions of Unix and Ultrix-11 on
a PDP-11/70 as an undergraduate - this one surely brings back memories!

After a prolonged outage Area 4 is now back on hecnet via a new Raspberry
Pi, so the archive on SLAVE:: is now available again (all the time the
windows vm that it is being emulated on is up) as well as a debian VM
hosted SIMH ORAC recreation.
I'm planning on using a (real) VAXstation during this years October
Retrochallenge (it starts tomorrow):

After a shaky couple of retrochallenge I've decided to step in and help out
with this one, but will also be hopefully using it as an excuse to spend a
bit of time on DEC equipment.
Also please note that it is DEC Legacy in Windermere, UK in two weekends:
9th/10th October.

This is a re-release announcement of TCP/IP for RSX-11M-PLUS.
This is version 2.7 of BQTCP/IP.
The reason for the re-release is that the patches mentioned for TTDRV
were incomplete, and lacking instructions about them. This has been
fixed now.
It's been five months since the last official update, and there been
various smaller improvements.
Highlights:
. Many daemons now run under NETUIC, if defined. Which means logical
names that are mainly used for configuration of these daemons now can be
in that group logical name table instead, which removes a bunch of
logicals from the global table.
. Improvements have been done to TCP to be able to have larger buffers,
if desired.
. Patch files for the TT: driver have been included, which if used, can
be combined with a new task to get logical names defined at login time,
which tells from where a user connected using telnet. See
[TELNETD]README.TXT for instructions on how to install the patches for
the TT: driver.
Detailed information on things that have been done since the last release:
TCP:
. Removed immediate ACK for TCP packets with PSH set.
. Added settable TCP syn queue maximum size
. Bugfix. TCP retransmissions failed if window size was 0.
. Reworked TCP FIN logic and buffer management. TCP can now deal with up
to 64K buffer size.
. Added IO.IFL function to TC:
. Added _iflush() to IPC library.
TELNET:
. Added TNC2 task to define logicals at telnet terminals at login.
. Added files needed to update terminal driver with additional
functionality. See README.DOC on TNC2 for details.
. Changed TELNET to run under netuic.
FTP/FTPD:
. Added the ability to set a session timeout for FTPD.
. Changed FTPD to run under NETUIC.
. Added handling of TI: in FTP GET/PUT commands.
. Added handling of TI: in FTPD STOR/RETR commands.
. Added handling of file attribute errors in FTP/FTPD.
. Improved ETA computation in FTP, when data rate is low.
MAILD:
. Improved MAILD to not use a separate MAILDN task for new mail. Local
mails are now delivered by MAI..., which also is responsible for the
local mail API.
. Rewritten maild automatic forwarding handling.
. Improved MAILD error mail generation.
Multinet:
. Improved active tcp multinet connection handling.
LPT:
. Fixed LPR mode of LPT spooler.
. Changed LPT to run under netuic.
HTTPD:
. Improved httpd error logging.
. Added more logging information in HTTPD.
NTP:
. Changed NTP to run under netuic.
DHCP:
. Changed DHCP to define NTP logical name in group table.
IPINS:
. Changed IPINS to define logicals for DHCP, FTPD and TELNET under the
network uic group instead of global.
Some additional notes:
As usual, I would recommend people to update as soon as possible.
The changes are not critical, but will lead to a much better experience.
The patches to the TT: driver cannot be applied automatically, but
requires users to apply the patches themselves, and then run SYSGEN to
generate a new system.
Once added, the TNC2 task can be run at login, and will define logical
names for the user telling where he is connected from, if using telnet.
The TT: driver patches also allows the updated MCR to give more
information with the DEV command (SHOW TERMINAL in DCL).
As usual, the distribution is available from:
ftp://mim.update.uu.se/bqtcp.dsk
ftp://mim.update.uu.se/bqtcp.tap
ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk
!!! BQTCP is also available through RPM !!!
(As an additional note, I have become aware of that there is some device
proxying access to the ftp service at Mim. This might lead to failure to
transfer large files. If you observe such problems, try connecting to
Mim at port 10021 instead, which is an alternative port for the ftp
server, and which circumvents the proxy.)
The documentation is also available through ftp on Mim, or also at
http://mim.update.uu.se/tcpipdoc
I hope people find this update useful.

Greetings
Just checking I'm still subscribed? I have just started trying to give my
emulated systems a little TLC to get them reconnected. I need to find out
why my Raspberry PI based bridge isn't responding, it has run faultlessly
in the basement for years and years, but something is amiss.
Regards, Mark.

Hi,
My power has been out since a severe storm, maybe tornado, passed
through 7/21 afternoon. My hecnet router is not on generator power,
so if any of my peers notice my absence, this is why.

I may have asked before on this list if anyone had the document that describes the differences between DDCMP V3 (as implemented in the DMC-11) and DDCMP V4.
I just found it. It is Appendix I of the DMC-11 microprocessor technical manual, EK-DMCMP-TM-002 (on Bitsavers).
Just in case anyone cares...

Hi,
I am trying to reach a guy named Mark Darvill, can?t remember which list he was on, regards the DEC/HP VMS hardware he asked me to hold onto.
If you are he, or know him, I can be reached via this email or mark.d.benson at icloud.com
Thanks,
?
Mark Benson
