Re: Your purple ceramic and gold plated TRW chips...
Beautiful pictures -- thanks for sharing!
TRW was a pretty major defense contractor (now part of Northrop Grumman) with roles in designing and manufacturing electrical components for satellites, missiles, and numerous other aerospace applications.

It's hard to find much specific about these particular chips, but they look pretty vintage to me.
I would definitely solicit some advice from the folks at CPU forum.

They have a real wealth of knowledge on these matters.
One web link I found requested an email for a price quote.
