Hey, interesting, those are almost identical. Yeah, I'm not sure "hybrid"
was really the correct term, maybe MCM? I see a couple components attached
to a piece of ceramic and I want to call it a hybrid... probably have been
looking at too many RF component databooks recently, LOL.
Thanks for noticing the similarity and posting... I guess those modules are
almost certainly some kind of memory? It's just such an unusual packaging
scheme for it.
Best,
Sean

I'm really curious what all those SIP hybrids are running down the one
side
of the board. I see it's got no less than 8
74181 ALUs so I figure this
has
got to be some kind of processor?
I looked at a picture of an MXV11 board today and I noticed similar, but
not identical, SIP hybrids (as you call them):

Perhaps a clue.
