We had an Elan E9 at my first proper job, this would be in 1984. I wrote a program to run on our Tektronix Unix box that allowed the EPROM programmer to be remotely controlled, devices programmed in bulk etc. On the strength of this, I arranged an interview at Elan when they were based in Crawley and was offered a job. However, I chose to work at a different firm, also in Crawley, as I suspected that writing software for EPROM programmers would lose its appeal after a few months.
