Apple Lisa 2/5 (1984)
Apple Lisa 2/5 is the January 1984 configuration that adds a 5 MB external hard disk to Lisa 2. Apple's Owner's Guide identifies that disk as ProFile and connects it to the external parallel port. It is neither the diskless base Lisa 2 nor the internally equipped 2/10.

Identity and date
Apple Lisa 2/5 is the January 1984 configuration that adds a 5 MB external hard disk to Lisa 2. Apple's Owner's Guide identifies that disk as ProFile and connects it to the external parallel port. It is neither the diskless base Lisa 2 nor the internally equipped 2/10.
Hardware
It shares the MC68000 processor and family architecture: 512 KB memory expandable to 1 MB, an integrated 12-inch display and a 400 KB 3.5-inch floppy drive. The manual documents 720 × 364-dot resolution and a separate keyboard with numeric keypad.
Use and expansion
The external disk stores programs and documents without occupying the floppy drive. The computer retains two serial ports and three expansion slots. For more parallel devices, Apple points to an expansion card: the 2/5's ProFile already uses the computer's parallel connector.
Important distinctions
Apple presented the 2/5 as a hard-disk system to which memory could be added for its integrated Lisa applications. That sales proposition does not prove that every surviving unit has the right memory or software today. Check computer, ProFile, cable and configuration separately.
