In a Datamation article on used machines, from a computer leasing firm:

	MODEL	   Introduced	MIPS
	7070	     9/02/58	.022
	1401	    10/05/59	.0074

I've gotten similar MIPS numbers for these machines from other sources,
except IBM.  The S/36 (5360, introduced 5/83) is about 0.2 MIPS.  I
don't remember the introduction dates, but Apple II is 0.15 and
TRS80-III is 0.22.

Multiple processors and intelligent controllers particularly affect
the importance of MIPS.  The S/36, for example, has two processors and
also has I/O interface processors.  One S/36 processor (CSP) seems to
be used as an MMU and arithmetic unit.
