The Ampex ARM10 was main memory for the PDP-10, which connected to the external memory bus. There were almost certainly at least two different forms, sharing only the name: a 256K word core memory unit (reported on the KA10 MIT-AI ITS machine); the large ARM-10L was also a core system.
Finally, there are reports of one which provided "four mega-words of ECC-protected semiconductor memory (using 64K DRAMs)"; that was likely the Ampex ARM20.
