Re: Primos
We had access to a Prime run by the Home Office. Its main use was to run a Lockheed bibliography database. It was possible to write well tuned queries for that, a characteristic which Google, Amazon and eBay seem to remorselessly root out of their query engines. The responses were in the form of references to microfilms of the original papers which were supplied to the labs which used it. Elsevier would have a blue fit if that were done today. The database was written in FORTRAN; for some reason a query managed to get it to start regurgitating the source code but I never managed to get it to repeat that trick.
We also had Pascal available. I can't remember what use I made of that but I must have done. We got our Onyx Unix box a little later and I sacrificed one of the TTY ports to connect to the link to the Prime (we must have had some sort of multiplexer on the Prime link). We didn't have tip, cu or the like on the Onyx so I explored the possibilities of fork() (and, indeed C which was new to me at the time) to write a simple equivalent so I could get on to the Prime from my lab instead of having to go down to the library. If I'd just been wanting to use the Prime for a literature search I'd have had to go to the library anyway to use the microfilm.
Again, thanks for a reminder of times gone by.
