Were the brackets on the 1700 cordwood modules shorter than the 6000
series? I've got a switch module here in a desk drawer--it's a
3-position switch labeled A O C and is illuminated with a couple of reed
relays on the PCB. PCB size is the same as 6000, as is the connector,
but bracket is

Nope, the Cyber 70s were very minor upgrades to the 6000 series. A
bunch of QSEs were made standard features, such as CMU (lower Cyber),
CEJ, ILR, etc. Same
I think the Cyber 70s used the later modules (the multilayer and/or IC things).

Don't know what the 1700 count was, but each 6600 had about 6,000
Don't let the (very few) online pictures of early 1700s (1704 and
1706) fool you - the things have a *lot* of modules when the options
are added. It might be that while the 6000 series followed the Cray
"simple/fewer" design philosophy, the 1700 line may not have.

That's an interesting observation, but I'm not sure I'd agree with you.
Statistically, it is more likely to be a 1700 module (a more common
machine). The front bracket is missing, which is the easy way to
distinguish the two types.

Gentlemen of advanced years who can remember CDC, cradle of Cray.
Can you tell me which CDC computer type these three boards belonged to? It
is for labeling purposes in my personal museum.

I am sure this will
The second one is a 6000 mainframe "cordwood" module. It should have a
two-letter module type code on the front.
The third looks like small bits cut from such a cordwood module (my wife has
some earrings made that way) but it may be they are actually complete items.
If so, I don't recognize
