Ok, then my guess is this either came from a KI or a KA with a very different memory box. I'll put it in the collection, and oddly enough I'll bet that it could work in the 11/05 if one of those boards ever blow out.

I know for certain they had KL and KS machines but no KA.

It is possible they had a KI machine.

So which class of pdp-10 did QZ have? KA or KI?

The one pictured should be from QZ which had PDP-10 machines.

Very similar to mine, however this one has only one of the core mats

There’s a piece of core on eBay

 which claims to be H214. The interesting thing is the label says 8K x 16 but 
the silkscreen says 8K x 19.
