8MB 0f physical RAM is not a bad complement, and implies that you have a 4MB daughter-card in place already. There is built-in VRAM enough to support mirroring on a CRT (two distinct groups of VRAM chips) if you wish. You can already support System 7.5, perhaps a little breathlessly under some applications. My greyscale PB180 handles 7.6.1 quite comfortably with a full 14MB of RAM, so you will get the idea.
If your machine shows 16MB of RAM space with VM off, but only 8MB of physical memory, it is probable that, as LCGuy writes, there is a third-party app. active. This could suffice for many of your needs if speed is not a consideration.
