Porter, I specifically mentioned "64k ROMs" in my last post, which indicates the "old Macs" I was speaking of; namely, the original Mac 128k and Mac 512k (not the 512ke). Indeed, Mac128 is also focused on something that would work with the original 64k ROMs. The old 64k ROMs are the keypoint here. We all know we can do many things with the 512ke and onward. The point here is to do miracles with the older 64k ROM Macs.
