Gurus,
I'm looking for your advice.
My DEC 3000 gave me a POST NVR error and after trying all the steps to fix it (reseating boards, memory, etc...) it looks like the RTC (DALLAS DS12871A) has died.
Searching on line I found some places marketing a replacement for DS1287 for old PC's but not sure if any would work for DEC given it had an A at the end in the model number (different pins etc...)
Given that this sounds like a common problem on early VAXen, I was wondering if of you have some recommendations on a good source to purchase a replacement RTC that will work with DEC equipment.
Thanks much!
Mike
. one more time. This time should be the last time, I hope.
108.65.195.50
As always, decnet.jfcl.com points to the correct address, so if your end is
using that you just need to restart the link.

Indeed. I haven't been up to that much just lately, been doing other stuff.
But I keep coming back to my failed H7864 PSU (from an rtVAX 1000), trying
to find the fault. Right now I have a little DEC Venturis PC onto which I am
just installing Windows NT 3.1 as I type. It isn't VAX or any kind of PDP,
but it is still a DEC machine!
Regards
Rob

Yes, very quiet. I?m also starting to think about Retrochallenge. This time I think I might combine my ham radio hobby with my retro hobby. I?m going to try to get a VAX to connect to HECnet using DStar ID-1 radios that act as 128kbps ethernet bridges. From my reading, they are true bridges, so should be able to transport non-IP protocols. I suspect this is the first time anyone will have tried to deliver DECnet over DStar :)

Well, about two weeks since my last announcement, but I figured I should
do another one.
I've cut a new release of TCP/IP for RSX, and I encourage everyone to
update to this latest release.
A short list of changes since my last release:
Documentation:
. I've worked some on the documentation, and filled out some parts that
were previously TBD.
TCP:
. Performance improvements. In general, I've improved file transfer
performance by about 20% by tuning when TCP ACK messages as well as
window updates are sent. On links where packets are dropped from time to
time, the performance improvements can be significantly higher.
. Bugfix. Retry counter were incorrectly reset under some circumstances.
. Bugfix. TCP did not resend an ACK if the same data was received twice.
. Bugfix. TCP sockets could erronously be left in a closed state with
no task. However, looking at the socket, it looked like a task was
associated.
FTP:
. Size calculation for stream type files in RSX mode was done incorrectly.
Applications:
. I've included a precompiled version of PCL.TSK
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
The documentation is also available through ftp on Mim, or also at
http://mim.update.uu.se/tcpipdoc

Hello,
My Vaxstation 4000-60 seems to be dead, probably due to a PSU problem (it does not power on). Does anyone know about options to find a replacement or to diagnose/fix it? (I just noticed it is dead, I have not even dissassembled it yet).

About four months since I last announced anything. There have been
various development since, and I figured I should encourage people who
are using BQTCP/IP for RSX to upgrade to the latest release.
A short list of changes:
TCP:
. Small bugfixes in various states.
. Bugfix in window handling. TCP reception could occasionally accept
data outside of window.
. Added ability to dynamically change transmit and receive buffer size.
. Bugfix. SYN packets could result in lost pool if sockets were closed
with outstanding SYN packets queued.
. Bugfix. If pool is full, system could crash on incoming connections.
FTP:
. Added SUMMARY, PROMPT, MGET and MPUT commands.
. Improved filename parsing and handling for mapping between local and
remote filenames.
. Bugfix. FTP would abort if a long file transfer took place, since the
command channel had a timeout.
. Much improved progress line for file transfers, including ETA and
delta between updates.
FTPD:
. Bugfix. If a file transfer was followed by an immediate close of the
connection, the file could be left in a locked state.
. Expanded time stamp information in directory listings to include seconds.
TELNET:
. Bugfix in telnet options processing.
TELNETD:
. Bugfix in telnet options processing.
IFCONFIG:
. Added commands for setting default and maximum allowed tcp transmit
and receive buffer sizes.
RMD:
. Added information on task page about UDP connections.
TRACERT:
. Added /NUMERIC switch
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
The documentation is also available through ftp on Mim, or also at
http://mim.update.uu.se/tcpipdoc
I believe the state of the code is now good enough that I expect there
will be fewer updates to the basic networking drivers in the future. I
plan to find some new protocols to work on next, and also improve some
of the current clients and servers as the need arises.
(On a different note, Madame.Update.UU.SE is now a CNAME for
Mim.Update.UU.SE, making the naming of the machine consistent between
DECnet and TCP/IP, in case someone wonders why the name have changed...)

I speak to machines with the voice of humanity.
Hello all,
I?m introducing someone new to the hobby - he?s just acquired a VAXstation 4000 VLC and will soon be needing a hobbyist license to get going. It?s looking like the hobbyist program keeps moving around - I?ve found what appears to be the current HP page for it, but they seem to be restricting licenses to only 3 recognized chapters - Connect/Encompass, Internet Netherlands, and Interex.ch <http://interex.ch/>. I?m either unable to understand the language, or the chapter wants real money for membership. Does anyone know how to get a membership number that HP will accept that is free?
Alternatively, without asking for anyone to break the law, I recall someone here has a method of generating a full set of keys (I have PAKGEN but it would take me quite a while to generate all of them). If someone could point me in the right direction off-list, I?d appreciate it!

Some of you are aware that I've been pursuing a long-term project of
constructing a museum in the Pittsburgh area.
I am proud to announce that we have hit a major milestone: We have
set a date for the first public opening. The Large Scale Systems
Museum will open its doors to the public on Saturday, October 17th,
just under one month from now.
This is to be a one-day provisional opening coinciding with an event
here in town. We may decide to open the museum regularly on a sparse
schedule afterward, or it may wait awhile, depending on how things go
on the 17th. The renovation work is ongoing, so it won't be perfect,
but we think it'll be good. A great deal of progress has been made
here in the past several months.
Many of the Really Big Computers here will be running and
demonstrated on a rotation throughout the day.
The event in town is a large "block party" of sorts that will
encompass much of the downtown area. A few highlights:
- A fancy department store that was located on this block decades
ago will re-open in their old store location to show off vintage
wedding gowns, and some people who purchased their gowns there in the
past will bring them back to show them off.
- A local winery will set up a wine tasting.
- A soldering workshop.
- A makerspace pop-up.
- A beer garden!
- The standard fare of food vendors, live bands, etc.
There are two other "Big Deal" tie-ins that I'd like to announce:
Big Deal #1: Many of you will remember my fiancee Autumn, who sold
handmade vintage-computer-themed soaps at the most recent VCF-East.
Her company, Apothecary Soap Company, will be opening its first store,
here in town around the corner from our main building.
Big Deal #2: While the details aren't yet finalized, C/PMuseum in
downtown Pittsburgh, curated by Corey Little and Chris Little, will be
relocating many of its exhibits, including some vintage game consoles,
to a temporary exhibit space just a few buildings down from mine.
Since C/PMuseum's primary focus is on microcomputers and the Large
Scale Systems Museum's primary focus is on minicomputers and
mainframes, so together we'll have great coverage of a range of genres.
My building is at 924 4th Avenue, New Kensington, PA 15068, right in
the middle of the block party area. New Kensington is about ten
minutes' drive from the Allegheny Valley exit of the Pennsylvania
Turnpike, Exit 48. It's a very easy area to reach, and there are a
number of decent hotels nearby.
I wish to extend an invitation to all of you to attend this event.
It's on Saturday, October 17th, from noon to 8PM.
Please feel free to forward this message to anyone whom you think
might be interested.
Thanks,
-Dave
