If it was a DEC memory box, I'd be more interested. We're not going to
throw it away, but I don't really see any point in trying to use it. If
it was core memory, that would be interesting, but it's just a humungous
box of 16K DRAMs, which aren't exciting at all. And it's certainly not
representative of the type of memory that was available when the machine
was introduced.
