The SMC-70 was the first computer to have a 3.5" floppy drive and perhaps the only computer with 3.5" to run CP/M (some MSX models did have a 3.5" floppy disk drive too, but they weren't CP/M-only machines.) In addition to the 280 KB 3.5" Floppy, the SMC-70 supported a cassette tape drive, and had an optional 8" floppy drive available for additional storage. It had an RS-232 serial port, 2 expansion slots, a port for an Analogue RGB Monitor, and a port for a TV set.
