It ran at 1 VUPS, making the 93/94 the fastest PDP-11.
Quote: Introduced in 1990. The last of the original (DEC) PDP-11s. Technically it is a re-enginered PDP-11/83 (it uses the same J-11 CPU chip) with more modern components (it could be modified for 20MHz clock frequency), and 2 or 4 MB's of on-board ECC RAM. It also features eight buffered serial lines (a terminal multiplexer emulated by a Z80) on the processor board.
