No, you have one of the replacement booklets. The S/360-20 ref summary
was a yellow card, similar to the S/360 larger systems "Green" card. I
used to have one, but someone stole it out of my desk some years ago. I
ordered a replacement and got the booklet (which has since come up
missing -- but I'll probably find that one once I get done unpacking --
just moved to TX from OH).
all my 360 fan-fold reference cards (gx20-1703) are green (except for blue fan-folds
that were specific to 360/67, 229-3174) ... i think that they changed to yellow
for 370 (i.e. gx20-1850)
the website (referenced elsewhere)
http://www.planetmvs.com/greencard/
shows 360 x20-1703-1 card as yellow
there was also a gcard ios3270 created ... which i've done a crude effort of
converting to html

the 360/67 blue card has stuff for 24-bit and 32-bit virtual addressing, control registers,
virtual memory instructions/operations, channel controller, and multiprocessor operation.
the channel controller was available as part of 360/67 multiprocessors and supported
configuration switches to operate as multiprocessor or partitioned into individual
uniprocessors ... with different physical channels and memory banks either dedicated
to specific uniprocessor operation or available to all processors (i.e. all
processors
in multiprocessor configuration could address all channels and all memory
banks). some
of the control registers were used to read-out the (manual) switch settings on
the channel
director.
one of my surviving "blue cards" that I got at the science center
http://www.garlic.com/~lynn/subtopic.html#545tech
is stamped with M's full-name ... i.e. GML (precursor to sgml, html,
xml, etc) was invented at the science center in '69 and the letters
are taken from "G", "M", and "L" last names (with morphing to come
up with the more familiar "markup language" label).
