This post made my childhood come rushing back. I was fortunate to grow up with a new-at-the-time Model I, which my father and I upgraded piecemeal from a Level I Basic ROM to the Level II ROM, then adding the expansion bay, filling it with 48K (16K at a time), then the chip that allowed displaying lowercase letters, and eventually 4 external double-density floppy drives. The Model 4 was the machine that I would daydream about while flipping through Radio Shack catalogs and "80 Microcomputing" magazine. I was determined that, when I grew up, I'd have a Model 4 with both banks of RAM (128K total) and 4 internal half-height floppy drives in the bays (I don't think that was possible, in retrospect), and the hi-res card. I still love the look of this machine.
