Secondary chip marked (only reputable vendors).  I currently have ~2500 8641
and several 100’s of the other variants.  Assuming 100% good parts, I have
enough stock to build at least 100 unibus boards (total) of various types that I
have planned.

And to forestall any questions on the topic, no I will not be selling any of the
chips individually.  They are there to allow me to build/sell the various Unibus
