As an absolute minimum I think you need 64K of RAM and 64K of ROM to build
a system that will allow you to run a couple of apps. If you want to
be able to log in and run a shell, you will need a filesytem. In this
case in addition to the 64K kernel ROM you will need 128K or so
of filesystem ROM, and probably 128K of RAM. The rest of the chips you have
in mind sound fine.
