    The MicroVAX 3100 models 30, 40, 80, 85, 90, 95, 96, and 98 all use the same
    memory SIMMs. These SIMMs were produced in 4 MB and 16 MB versions. The same
    memory is used in the VAXstation 4000 models 60, 90, 90A, and 96.

    In the MIcroVAX 3100 models 30, 40, and 80, as well as the VAXstation 4000 model
    60 the memory SIMMs can be used in pairs. In the rest they must be used in sets
    of 4. I'm not real sure about the MicroVAX model 85, but since it's a slowed
    down version of the model 95, I'm guessing sets of 4.

    I believe your model 40 is limited to 72 MB of memory, with an initial 8 MB on
    the motherboard. This system will run quite well on the 24 MB you have. Memory
    requirements will depend upon usage, with DECwindows being a bit of a hog.
    VAX/VMS has a rather small footprint in comparison to Alpha.

    I've got some of the 4 MB SIMMs I'd part with, but the shipping to Australia
    might be an issue. Knowing all the systems that used the memory should help you
    find some. A pair of the 16 MB SIMMs would be the best choice for you. I've
    seen these SIMMs on E-Bay, usually specified as VAX 4000 memory.
