360/91, 360/95, & 360/195. There was an initial redo of 360/195 as
370/195 but it never got virtual memory.
The 370/165-3 was 2.5 to 3 mip machine (depending on cache hit and
workload, etc).
The 370/158 was a processor engine that was "time-shared" between
performing the I/O channel functions and 370 instruction set.
For the 303x, there was a channel director for I/O ... which was
effectively the 370/158 processor engine with just the channel I/O
microcode (and no 370 microcode).
A 3031 was a 370/158 processor engine running just the 370 instruction
set microcode and no channel i/o microcode ... coupled to a channel
director (which was a 370/158 processor engine running just the
channel i/o microcode and no 370 instruction set microcode).
A 3032 was a 370/168-3 redone to use channel director ... instead of
the 168 outboard channels.
A 3033 started out being a 370/168-3 remapped to newer technology.
The 168 used 4circuit/chip logic ... and the 3033 had chips with about
ten times the circuit density ... and the chips ran about 20 percent
faster. The 3033 started out just being a straight wiring remap to the
new technology ... which would have given a straight 20 percent boost
... from 3mips to about 3.6mips. Late in the development cycle, there
was some rework of critical logic to take advantage of the higher
circuit density ... eventually yielding a 50 percent improvement
... aka 3033 were about 4.5mip machines. For operating system and
regular data processing type codes ... the 3033 was almost as fast as
370/195 (however, for highly optimized codes utilizing the 370/195
pipeline would run twice as fast).
Following the 3033 was the 3081 ... the initial 3081D was a pair of
five mip processors. The later 3081K was a pair of seven mip
processors. There was a 3084 which was a pair of 3081 in a 4-way
configuration. 3081 & XA architecture were code-name 811 ... for
nov78.
370/135 turned into 370/138 and then 4331
370/145 turned into 370/148 and then 4341, and then 4381.
3081s had a UC.5 microprocessor for the service processor.
After the 3081 was the 3090 ... which had a pair of 4331s running a
highly modified version VM/370 release 6 for the service processor
function.
When I was doing the RFC1044 support for mainframe tcp/ip ... the
standard code could just about saturate a 3090 engine getting
44kbytes/sec thruput using standard adapter (8232). Tuning the RFC1044
at cray research ... between a 4341-clone and a cray would hit nearly
1mbyte/sec using about 20 percent of the (4341) processor.

oops, that is
370/135 turned into 370/138 and then 4331, and then 4361
the service processor for the 3090 started out to be 4331, but by the
time it shipped ... it had turned into a pair of 4361s (not 4331s).

The second date appears to be either date-of-completion or
close to date-of-1st-delivery.... what's the first date?
Start-of-project? Conception?
The 64-09 is interesting though... While some programmers
were designing SIPROS, Cray had started writing the Chippewa
OS in June '64 and had most of it done by November... with
some not-quite-final tweaks dated 21 Dec 1964 (1AJ, Advance
Job).

What's SIPROS?
Douglas H. Quebbeman
Obviously an acronym, it was the OS being designed by the
programming gurus at CDC. it was a flop, and I'm not sure
anyone actually ran it for any period of time. Instead,
most sites created their own variants of Chippewa OS. David
Sachs at CMU took Cray's octal source and added mnemonics;
it then evolved along separate lines into SCOPE and KRONOS.
SIPROS is probably something like SIxthousand Programmable
Operating System...
