  Hello!
 Oddly enough the phone company besides having a good interest in
 things DEC related, also made stuff in Dayton.......

 Which model was considered to be a DECwriter? I seem to recall seeing
 one once, and also recall the discussions concerning the thing in a
 certain novel........ (Or other book) 
The first device called DECwriter was the LA30, an amazing piece of junk known to jam
every few pages. It also came with a really bad keyboard. Was it uppercase only? I don   t
remember anymore. It needed fill after the carriage return or it would lose characters
(and jam even more often, too). We had one in college for a short while.

Next came the LA36, which was something entirely different. Rock solid, and it didn   t
need fill after carriage return. Upper and lower case, of course.

The LA120, if I remember right, was the first DEC printing terminal to do bidirectional
printing. It used the T-11 as its microcontroller to make that level of sophistication
possible.

The LA180 receive-only printer was, I think, a derivative of the LA36, not the LA120. The
1976 Peripheral handbook seems to support that. Note that there also was an LA35, a
receive-only variant of the LA36. The difference is that the LA35 had a serial interface
while the LA180 had a parallel (line printer style) interface.
