I remain sceptical that 1969 was the first time they connected two computers together 'with a long grey cable' - though it probably was the day the first test was done with ARPANET. In 1969 I was at University and we used to log onto the computer there via a remote teletype terminal. Indeed even in 1968 this was very common. I would be surprised if somebody somewhere had not had two computers connected in a primitive network. OK, computers at that time were pretty crude, 4k of core store and normal input via punched tape and cards. At least we didn't have to worry about viruses....
