Get a copy of
BigMac, and go ahead. it's a nice all in one
environment, and works fine on every Apple.
Oh Yeah! BigMac (or as we used to call it at Software Productions,
"BigHack").
My favorite was always LISA, Laser Interactive Symbolic Assembler, a
complete editor/asm/runtime kind of setup.
I need to look around and figure what the status is of the program, but I
have most of the versions of it that ever existed.
