Yes, checking it is the easiest way. Getting one de-capped and imaged would also be interesting too. OT: The differences between the static ram 6566 and dram 6567 are also interesting, you can see how they hacked multiplexed address lines into the non multiplexed design (the static ram version was finished first because dram was too expensive and they would be able to ship the Max sooner).
