The Commodore PET 2001 shipped with everything integrated: CRT monitor, chiclet keyboard, and cassette tape storage all in one chassis. No external peripherals needed. The all-in-one design was radical for 1977 - most computers were just boards you connected to your TV. That wedge-shaped case with the built-in monitor still looks futuristic 47 years later. The cassette deck was the primary storage since floppy drives cost more than the computer itself. Load times were brutal (minutes for small programs) but it worked. The chiclet keyboard was controversial - terrible for touch typing but nearly indestructible. The PET ran a 1 MHz MOS 6502 CPU with 4KB RAM (expandable to 8KB). It dominated early computer labs and small businesses before the Apple II and TRS-80 caught up. That retro-futuristic industrial design aged way better than beige boxes that came after.
