Memory - We have an Ampex 4 megaword ECC memory box

I've done preliminary design work on a board to
plug into the S bus
cable slot and implement the 4 megawords of memory using six 8M*8 SDRAM
chips.

If it was my machine, I'd probably try to get the
memory box working,
even if it eats power (what? 3kW or so?). On the other hand, a new memory
subsystem is certainly a reversable mod, and it's something worthwhile...
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.
