  • So I came to Nottingham in 1980 to do a physics degree and

  • Worked through that but towards the end of it

  • I got very interested in computing and fact, I ended up doing physics with computing

  • that's where I met Dave and the other people who were setting up the early computer science group and

  • Then he said after I'd finished that I've got a bit of spare money. Would you like to work on some typesetting stuff?

  • There's all sorts of interesting things happening

  • So I did. I worked on that for a year, I think, with Dave doing various things

  • including this

  • connection for the exams machine and all that interesting stuff

  • Never mind said Julian quite rightly. So, we'll keep the lower level

  • And then I got really interested in networking us as that was just starting to come about and I worked with another

  • lecturer called Hugh Smith

  • and he had contacts with UCL and so we got into this sort of Internet and ARPANET and

  • Early connections to that and I started working on

  • email software to try and make sense of all this stuff that was going on get rid of all these

  • exclamation marks in your routes and things like that and

  • Just try and make it simpler

  • It was quite early on so it was about

  • 1984 or three I think I got involved in it. At that time

  • The the internet was well, it was all just ARPANET. So it was the

  • American connection and we had a very very tenuous connection

  • we had some friends at University College London, and they had a satellite link to the ARPANET they'd had for a while and

  • we were in the maths building which is where we are today and

  • We didn't actually have a connection to the outside world

  • But (the) Psychology (department) did. So you could connect across to Psychology's computer and dial up London

  • Log into one of London's nodes and then you could use the internet

  • Very very slow. And of course it was going across satellite

  • So you connect to... I don't know, there weren't very many sites, but there were a few places you can pick up software

  • So you'd log into those?

  • but because it was going over a satellite you typed a letter a

  • and it would take about three seconds for the a to come back and so

  • You'd start typing and then you get very confused halfway through and have to delete it all and this was all painfully slow

  • But we thought it was wonderful at the time

  • So it was about you know, 20 minutes or something to get onto the Internet from here

  • But but we did manage it. Alongside that at the same time

  • There's sort of a more anarchic network called Usenet, which was just - that was machines

  • That you were friendly with. You talk to other machines and and a whole grouping came out of that

  • so we also have that so you could use that alongside it so you could

  • Send email to somebody and say do you know a good site

  • I can go to to pick up software for?

  • this, that, or the other and they'd send something back over that but it was all very very

  • disconnected

  • so, I remember we connected to Lancaster and then Lancaster connected to Kent and Kent connected to

  • Amsterdam and Amsterdam was the European gateway. They could then connect - and er, at a very early stage you actually have to work out your route

  • so if you wanted to email somebody you'd say right so go from Nottingham to Lancaster to Kent to Amsterdam to

  • Seismo to Rutgers to something other and you could eventually work out where to go and how it would get there

  • So it was

  • So much fun

  • We had email in the department for a long time and then as psychology and other places got connected. We sent it around campus.

  • I can't think who I would've send the first one to probably somebody at

  • University College London because we did a lot of work with them early on and eventually had some

  • Connection which is how we got connected to the Internet

  • I do remember

  • desperately trying to get in contact with Brian Kernighan and

  • Sending email after email along these different paths - via Amsterdam and Seismo to... It was called "Research" - Research

  • Everybody's

  • Name was just their computer name

  • So "Research" was the AT&T computer node, so and eventually I remember it was late on a Friday night

  • I was watching the logs and suddenly saw an email come in. It was from Brian

  • Rushed down to Dave Brailsford, and said look, look, we've got a connection

  • here's the route that you need to use and he scribbled it down and

  • From then on we had contact there very soon after that. We started sort of collaborating. So I was working with somebody in the

  • California and we were working on software that got switched around

  • so I'd be working on it during UK time and then he'd be working on at Californian time and then he'd send me changes and

  • Yeah, that was mostly done over email we didn't need

  • Very much

  • Because in the UK we were still we weren't using tcp/ip. We were

  • Told we had to use x.25 at the time

  • But we cheated and we ran some

  • tcp over x.25 and we ran strange protocols that allowed us to

  • Connect to the Internet and we did actually even managed to have a sort of talk

  • System where you could type a message and it would appear in California and vice versa

  • That was a great day when that first happened

  • I guess that was about nineteen eighty six or seven when that we managed to cobble together enough protocol to get that all to work

  • SEAN> And you mention email the instant thing you think of these days?

  • It's probably webmail or a client email with attachments just being dealt with for you. Can you talk me though that?

  • You couldn't do attachments at all though, you could sometimes because it was all just text

  • so sometimes you could wrap them up in interesting ways and

  • There was particularly one self-extracting

  • It was called a shar archive self-extracting

  • it was actually a small shell script program for UNIX and so

  • Your message arrived and you just ran the contents of the message as a program and it extracted itself and you could send files that way

  • but

  • That was fairly late on because we had very little bandwidth at the time. So it was more very quick short emails and

  • This is a place to pick up a file from we would try and get the file somewhere near nearer to the person

  • So that they could pick it up with a reasonable speed. So this is a message I've saved from

  • 1987 and this is the path you can see here

  • So it starts off over here. This is the person and then this is all the places

  • It's been through, Seismo was a popular place in I think it's in Virginia or somewhere like that

  • But it had great connectivity to lots of other places and then down here

  • We have MC VAX, which is the European node

  • And then it trickles across the UK to get to us from here

  • So, you know

  • That was kind of one of the early messages and you had to remember these paths and write them down so that you you could

  • Get back to them and this is kind of the route

  • it took it jumped around in Europe a little and then left over across the

  • Atlantic and then rattled around there until it ended up where it went to and this is just a,

  • This is the Sat net that was

  • So this bit here is all of the US and there's a connection here coming over the satellite to Goonhilly Down in

  • Cornwall and a landline up to UCL

  • I remember when they finally got to upgrading that they went to a transatlantic cable or something TAT 8 or TAT 6

  • Transatlantic telephone cable 6 when that was laid down. Suddenly. We had more bandwidth than we ever knew what to do with

  • Until about two months later when we fully utilized it all

  • That's the way it goes

  • That was what a lot of the internet was for and that's still what the Internet's for

  • actually, serving very little purpose but you know back then they took it to a to a different level and

  • we'd have to go to this really dark room and

  • The computers were green little I had an Amiga computer, right? This is like an Amiga 500

So I came to Nottingham in 1980 to do a physics degree and
