@cstross@wandering.shop @jackwilliambell@rustedneuron.com @ravenonthill@mastodon.social Back in the day, at least one model of X.25 packet switches from Hughes were programmed in Pascal. This was when Pascal was the big teaching language. As it was explained to me when I asked "why not C?", Pascal was fast enough to meet the requirements and they could hire new grads who knew Pascal without having to train them in C. The FAA's NADIN II packet switching network (long since retired) used these switches.
