There were hard drives around in the mid 70's. I used a couple of PDP-11 
machines in 73/74, PDP-11/40 and a PDP-11/20. Each machine has 16 
kilobytes of memory. One had a fixed head hard drive with a capacity of 
256 kilobytes (yes, that's kilobytes). The other had some exchange 
cartridges whose capacity was 2.4 megabytes. These machine occupied 
several 6 foot high cabinets!
