It does not apply to this model. The LA-180, AKA DECprinter I, is
natively a parallel device. There was an optional serial converter
board, which is what Ed is asking about, but I have never seen one.
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.

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.
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.
