----------- You are a bit off as to size/time. and I recall a late '50's version computer (McBee ) which was desk size and had a wonderful 4KB drum memory and 500ms multiply time. This was followed by an IBM (1600? name lost in antiquity) which was more powerful and still desk sized so the development of smaller computers was definitely there- the concept of desktop units was there- the technology wasn't. Many mainframe IBM's at that time would occupy part of a large room - the bulk of the dedicated room being used by periperals and people-hardly a building floor in most cases-admittedly air conditioning and power supplies took up about as much space. By the later
60's there were definitely remote terminals and, in the 70's remote desktop terminals with monitors and keyboards were appearing -first step towards desktop computers.-- Don Kelly snipped-for-privacy@peeshaw.ca remove the urine to answer
