Hi all --
Got myself a nice looking DECwriter Correspondent (AKA the LA12). It's
having a bit of trouble moving the carriage assembly and I can't find a
service manual for this thing. (It's similar in some respects to the
DECwriter IV, but the mechanical parts appear to be fairly different.)
The carriage assembly (print head, ribbon) is carried from one end of
the platen to the other via a cable attached to a servo motor on one end
and a pulley on the other; in the middle of this cable is a small metal
ball -- this ball is (as far as I can tell) meant to sit in a small
"cup" on the underside of the carriage and when the cable moves, the
ball pulls the carriage along. I'm assuming this was done this way
since the Correspondent is meant to be portable, and allowing the
carriage to break free of the pulley mechanism would probably reduce
damage in the case of a sudden shock (like getting dropped.)
So far so good -- unfortunately the vast majority of the time, the ball
leaves the carriage behind (especially on carriage return) and I can't
quite figure out what's out of tolerance -- the carriage appears to move
smoothly, nothing is bent out of shape or broken as far as I can tell,
and there's plenty of tension in the cable. There's also not much to
adjust here so I'm kind of puzzled.
I've put up a few pictures (and a short video demonstrating the problem)
with the print head/ribbon removed here:

Anyone ever worked on one of these before? Any ideas?
Thanks as always,
Josh

Greetings folks.
The additional drive was added to ccmp server last night. No problems
encountered other than for some oddball reason xenserver added it as drive 4
instead of drive 3. It thinks drive 3 slot is in use but it's not. I can
live with ada3p1 ;)
I've got my hands full with some work on bitsavers as well as ongoing client
workload, and some rough edges still remain on the mailman "two views of the
same list but joined at the hip" thing. That needs to be addressed quickly
before the current/new archives get incoherent but I'm short on available
time.
So, is there anyone that is *very* well versed in mailman "under the hood"
that can do a one-time assist with the following:
1) Get the "two views of the same list but joined at the hip" working
the way it previously was. I have some details/recollections on this, but
not complete "do this" instructions.
2) There has been an ongoing issue for years with the "forgot password"
emails and/or the new subscriber email verification not working right.
3) Please for the love of god figure out why every single post to the
list gets me a "bounce rejection" notice to my mailbox and stop it.
4) Integrate multiple fragments (I have several, if that's not complete
other listmembers have mentioned they can supply any missing fragments) of
the list archives into one archive that is complete.
FYI - when rebuilding the server a couple weeks ago, I switched from
sendmail to postfix, so a passing familiarity with postfix would be helpful
as well in your endeavors above. The OS is FreeBSD r10 p11.
If anyone is versed in the above and has a bit of time to spearhead the
above tasks, please email me off-list.
Also - once the archives are cleaned up, two other folks have volunteered to
get archive searches to be "much improved".
Thanks!!

That would be really useful.
If I had to bet, I'd go with the 8: DEC SPC/MUD memory boards often have CA1
jumpered to CB1 (NPG), and I don't see that here. And the way CC1 is ganged
to CF1 to CT1 is very odd - CC1 is Parity A in an SPC/MUD slot. (Yes, it
could be for a specially wired system unit - but those don't usually use hex
cards.) And then there are a number of different kinds of component (e.g. the
transistors in the cans, TO-18 I think?) which seem to be in multiples of 12.
Too bad there's no picture of the edge of the handles to give us an M-number!

So, my local bookstore guy has an IBM 5151 monitor for sale, which is
surprising because:
a) I haven't seen *any* vintage IBM PC kit locally in the last 8 years,
b) I picked up a 5160 with an MDA display adapter but non-IBM monitor from
John over in Duluth a few weeks ago, and I was thinking what a shame it was
that it didn't have the original IBM screen.
So, it's almost like it's meant to be, or something...
Of course working condition is unknown, so before I commit to it, are there
any common showstoppers with these displays (failed CRT, yoke windings,
LOPT etc.) - or are whatever faults that may be typical with them all in
components that are still available?
(I'm kicking myself a bit because he said I was welcome to bring it home
over the weekend to try it out and then bring it back if I decided I didn't
want it - I just couldn't remember at the time if the 5151 was the MDA
display or something else, but with hindsight I probably should have just
taken it regardless!)

I'm trying to install the Whitesmiths C compiler under RSX11M using
FLX (using the Whiteshmiths c compiler distribution tape V2.25 from
bitsavers).
Alas, 'FLX' says the tape has zero files and directories, while a dump
under Linux shows definitely some contents.
I tried both the simh & tpc format, no luck here yet.
Am I missing something?
The command I used is 'flx /rs=ms0:[*,*]/do'
Thanks,
Ed

Zeg NEE tegen de 'slimme' meter.
There's about an 80% chance that I will reboot the classiccmp server tonight
to add another 300gb drive to it. Total expected downtime would be about 30
seconds.
If I do wind up doing it tonight, I'd expect it to occur vaguely around
8:30pm-ish CST.

Longest of long shots, but does anyone happen to know the keyboard
connector pinout on an ADDS 4000/260 terminal?
I have such a terminal here, and it has a 6-pin RJxx-type socket, but the
keyboard which came with it would appear to be for something else, and has
a 4-pin RJxx plug (I'm not sure of the actual RJ designations, but they're
physically different, albeit close - the keyboard one fits in the
terminal's 6-way socket, but is too loose to make contact on its 4 pins)
However, the manual for the terminal mentions supporting a PC keyboard, so
it's possible that a standard PS/2 keyboard with the PS/2 connector lopped
off and replaced with a suitable RJxx connector would work - i.e. the
clocking method and scancodes are identical - if I knew the pinout (it's
also possible that the same is true of the keyboard that came with it - the
physical layout's identical to a PC, but with the addition of a 'select' key)
cheers
