The DEC LA36 DECwriter II Terminal
Date: 1974. "The LA36 provides true 30-character per second printing for full
utilization of a 300-baud communications line without the use of fill
characters. Printable characters are stored in a buffer during the carriage
return operation; and while more than one character is in the buffer, the
printer operates at an effective speed of 60 characters per second."
Adjustable pin-feed tractors take up to 6-part forms, with or without carbons,
from 3" to 14 7/8" wide. Optional ROMs were available for APL as well as
Katakana and other character sets. The later LA120 model looked the same but
printed 120 cps. Later still was the desktop LA34, which could print not only
characters but also Sixel graphics.
