Erm, first computer I ever used was an IBM Sys/36 Mini, about 4 ft high, 3 ft deep, and 5 ft long, came with a 55kilo hd with 4 18inch platters and 8 read/write heads, the hd had a transparent casing so you could watch it working...

Removable media consisted of a 2400ft magtape drive, and 8in floppies, which came in 10 disk magazine loaders...
