As this is port-alpha, your machine should be a DEC3000, not a pmax-based
DECstation.

The DEC3000-300 accepts PS/2-SIMMs with parity only. You can use pairs of
8MB or 32MB modules. The usual PS/2-SIMMs for PCs have no parity bit and
can't be used in the DEC3000. The memory check at startup recognizes modules
without parity, but if you do a TEST MEM you will see the truth :-)

My DEC3000-300XL was not too picky about memory modules, single-sided 70ns
8MB modules with parity ripped from an old 486-PC work perfectly. It even
accepted modules of different brands within one bank.
