The first hardware revision, the Lisa 2, was released in January 1984 and was priced between $3,495 and $5,495 US. It was much less expensive than the original model and dropped the Twiggy floppy drives in favor of a single 400k Sony microfloppy. The Lisa 2 has as little as 512 kB of RAM. The Lisa 2/5 consists of a Lisa 2 bundled with an external 5- or 10-megabyte hard drive. In 1984, at the same time the Macintosh was officially announced, Apple offered free upgrades to the Lisa 2/5 to all Lisa 1 owners, by swapping the pair of Twiggy drives for a single 3.5-inch drive, and updating the boot ROM and I/O ROM. In addition, the Lisa 2's new front faceplate accommodates the reconfigured floppy disk drive, and it includes the new inlaid Apple logo and the first Snow White design language elements. The Lisa 2/10 has a 10MB internal hard drive (but no external parallel port) and a standard configuration of 1MB of RAM.
