1990. The last of the original (DEC) -11s. Technically it is a re-enginered /83 (it uses the same J-11 CPU) with more modern components (it could be modified for 20MHz clock frequency), and 2 or 4 MB's of on-board parity RAM. It also features eight buffered serial lines (a terminal multiplexer emulated by a Z80) on the processor board.
