That is 160 times slower than a Dorado, which did about 400K bytecodes
per second. So their Modula-2 implementation would do something like
2400 bytecodes per second. Apple Smalltalk on the Lisa was about four
times faster than that, for example.

Sun introduced their first 68020 machines in September of 1985, so
either the 1984 article was based on their earlier 10MHz 68010 computers
or on non Sun machines (which I wouldn't expect given the previous
Berkeley Smalltalk project).
