From Wikipedia
- The VAX 8650, code-named "Morningstar", was a faster version of the VAX 8600 introduced on 4 December 1985. It was originally to be named "VAX-11/795", but was renamed before launch. The VAX 8600 was the last VAX to be 100% compatible with the VAX-11/780 and VAX-11/785, to have the PDP-11 compatibility mode, and to use the SBI also used by the VAX-11/78x. The CPU had a 55 ns cycle time (18.18 MHz).
