Hi,
After being kept in a corner, I unearthed my LA180 aka DecWriter I.
After powering it up, no magic smore, but some humming from the fan.
The selftest went ok, but the ribben needs replacement, the characters
were faint.
Now, I want to hook it up, so I opened the backpanel to locate the
serial line, only to find out is is not having the converter board
which is an LAXX-NY for EIA signals according to the user guide.
So, is there someone having this board and is willing to sell it?
Thanks,
Ed

Bravo! I like LA180s a lot. I used one for a long time. I miss the

I don't have any of those serial interface boards. Bus interface boards,
though...I think several of those will drive the LA180, but the one I used
with the LA180 on a Unibus machine was the LS11. It's a good setup. I have
a few spares; if you want to try driving it that way, send me your address.

Hello Dave,
I do have a few of the LP11 cards, so I'm covered there.
I'm looking for the converter as I want to use this printer
also when not connected to a PDP-11.
The printer just needs a bit of cleaning, especially the platen,
as it has some fly rust. Nothing a good rub using a sink
cleaning pad to get it removed.
The only thing left to do is to locate my box of greenbar paper.
Thanks,

Yep. I used to run them all the time. I got one in college because it was
handy for printing out listings on greenbar paper and was a lot more
affordable than a band or chain printer. It probably got the most
time on an LPV11 in my RT-11 box, but it worked great with an
LP8E on my PDP-8 too. I heard it was possible to cobble up a
cable (maybe with an inverter or two?) to use an LA-180 with
the printer output on a DMF-32, but I only read about it, I never
tried it.

If it's just a Data Products interface (I've never had an LA180), I did an
i8051-based (actually Dallas DS5000) RS232-to-DP adapter a few years ago and
it was a piece of cake (most of the effort came from getting sidetracked with
adding a command prompt and saving various settings in a 93C46 EEPROM). Yes
I agree it could be done in loose parts too (although flow-control could get
interesting, especially if it's XON/XOFF). But if anybody wants schematics
or gerbers or firmware (assembled with Alan Baldwin's RT-11 cross-assembler,
if I remember right), drop me a line. The PCB uses a Centronics connector
with a pinout to fit the Black Box Cent-to-Winchester cable, which at the
time (10+ years ago) was the cheapest/only way I could find to get new Winch
connectors.

Hi,
After being kept in a corner, I unearthed my LA180 aka DecWriter I.
After powering it up, no magic smore, but some humming from the fan.
Probably needs a drop of oil. Some of these machines had open-frame fans
with shaded pole motors. The bearings have oilholes. If so, squirt some
light machine oil in there.
The selftest went ok, but the ribben needs
replacement, the characters
were faint.
Now, I want to hook it up, so I opened the backpanel to locate the
serial line, only to find out is is not having the converter board

I don't know if it applies to thsi machine, but some DECwrited have 2
flat, white, 8 pin mate-n-lock conenctors on the logic board. One is a
20mA current lopp with the normal DEC pinout. The other is where the
converter conencts, it's TTL level seiral I/O and power lines. The
converter is quite simplke, jsut a 1488 and 1489 IIRC.
If yours is like this and you cna fidn the conenctions to that conenctor
(or the printset), it would be very easy to make the RS232 converter if
nobody has a spare.

Every LA-180 I've seen (and I've seen a few) was connected via
40-pin ribbon cable and driven from some flavor of DEC parallel
printer interface (LP11, LPV11, LP8E...)
I'm sure someone out there has a spare LAXX-NY or two, but I
don't think they were common.

The only (standard) interface is the one requiring the
LP11.
The LAXX-NY is an option for the printer and handles the EIA,
the LAXX-NX is needed for 20mA
Ah yes... I know the machine to which yuo refer now. It's covered in the
printset for my MINC, which has an LPV11 as standard. I never got the
printer with the MINC though...
Do uou need to add a serial interface to it? I would guess that linking
it to a Centronics output port would be quite simple

Hmm, that could be an interesting route to a solution.
The standard interface uses 7 / 8 bits plus some ready
signals, so it may be indeed possible to use a Centronics
port with a little bit of supporting logic.

to get the S.O. seriously upset with me and park it in the living room.

The local (San Francisco Bay Area) Craigslist has
had a posting for a
FREE but non-working DECwriter III for over a month, now. It looks like
he just has no takers for the thing.
It's worth a rescue, if only to obtain a pile of spare parts. I seem
to recall someone asking about a space bar recently.

Oops! And speaking of which, I haven't sent that out yet. I'll try to do
that tomorrow.
I'm a bit of a newbie on the list, but I've been a pdp11 guy since
1973; anyway, I'm also looking for an LA120 spacebar; I posted a
request to the vintage computer dec forum some months ago, but got no
replies.
I've been building a small personal collection of unibus and qbus
systems, and my recently-gotten LA120 is in very nice shape, with that
one small exception.
So, if you've still got one, I'm interested.

No, the LA180 is a different beast. First of all, it prints
unidirectionally, while the LA120 prints bidirectionally. There is a
keyboardless version of the LA120, and I have one here...It just an
LA120-xx, I will have to check the suffix later.

I recently got my Teletype ASR33 working against TOPS-20 on SIMH. It really
was a trip down memory lane. I am in the process of getting some more
ribbons, need to make a few adjustments and then I can get some good hard
copy.

New subject: Help in identifying an old plugboard
I'm trying to help a guy I met at the Maker Faire that collects
plugboards. He has one he cannot identify.
There is mention of magnetic tape storage and the like written on the
board. It also mentions a "character
generator" so the system probably had some sort of CRT display. Could
well be military. Also, the plug-in
cable ends don't look like the ones I have from IBM or UNIVAC.
I put up his photos here:

Amongst the stuff that the college dumpstered, was an IBM plug-board
clearly lanelled, "COBOL Interpreter".
Before we get into the unlikelihoods, . . .
We assume that it was for the [long gone] card interpreter,
and was jumpered for optimal display of the fields of a COBOL unit record.

Yes there is some lag. That is to SIMH running on my local PC. I don't know
the cause but I wonder if it is the serial interface code in SIMH.

The LA180 predated the LA120 by 5 or 10 years,and came out shortly after
the LA36.The LA35 (I have one left) is a no kybd LA36. The LA180 was called
the Decprinter I. The Decprinter II is an LA120-RA or RO and came out
shortly after the LA120.

Hi Ed,
I'm still looking for a LA180 for myself! Care to trade for a LA120AA, DA,
or RA?
I should have the serial interface here somewhere, but I know I have the
PDP8, unibus and q-bus interfaces. Where are you located?
Thanks, Paul

After powering it up, no magic smore, but some humming from the fan.
The selftest went ok, but the ribben needs replacement, the characters
were faint.
Now, I want to hook it up, so I opened the backpanel to locate the
serial line, only to find out is is not having the converter board
which is an LAXX-NY for EIA signals according to the user guide.
So, is there someone having this board and is willing to sell it?
Thanks,

From my city to Amsterdam for something the weight of a
packed LA120 would be $890
if shipped via FedEx. That's economy shipping, too!
Priority is $1325.10!
That'd definitely be killing.

So how much was a LA120 New?, when you had cheap 6 month shipping.
