Not sure if it is real CDC 6600 memory or not, but it does look like most core made from the late 1960s or early 1970s. It is certainly not Cray memory — no Cray ever used core memory.

The CDC 6600 is my favorite weird-ass architecture: it used 60-bit words, instructions were variable-length (15, 30, or 45 bits), and multiple instructions could and were packed in a word. There was also a 7-word instruction cache, and so people would reorder instructions in their loops to avoid padding their code with nops (and fit then into cache). Goofy stuff. I really with I had that old APL terminal I nabbed in the 90's. Overstrike! Even better.

Mr. Seymour Cray at least worked on the system design of this machines. See http://www.cray-cyber.org/memory/scray.php for some further information. We at Cray-Cyber.org (located in Munich, Germany) own several of those core memory modules, also the one in your picture :-) wolfgang I’m pretty sure, that this core memory isn’t from a Cray supercomputer, but from a Control Data 6600 series of computers.
