Yes, the PB2400 worked fine with 16MB and booted up and ran just fine with the 64MB card installed in the previously empty expansion slot but, after booting, still showed only 16MB total memory. I am running MacOS 8.0 and the first order of business after installing more memory was to install a newer OS - something I cannot do with the original 16 MB. (OS 8.6 requires 24 MB for installation).
