Oldest software you had to use day-to-day for work?

Probably the inventory software at my old job when I was in retail. They used something called the AS400 which was a super old school UI with green text on a black background. Google says it's from the 1980s and ide believe it. Fucking so brutal to use...

@hexc For me, it's the inventory software as well, in a beverage distribution company.

@hexc I used AS400 to see orders, type of products and quantity of a certain product.
They told me that it is made in RPG language (1960). Anyway there is th GUI version made in Java. It's quite difficult to learn how to use it, but then it becomes really simple :)

Mmmh... The control software of a WatchGuard firewall that only runs on a WinXP VM. I'm not at work and can't check the model, but I recall that piece of junk was considered already obsolete in 2009 or so XD

Turbo C++.

PeopleSoft, the version we used was released around 1998.

They only upgraded it last year to a system that's almost worse.

Vi

Emacs, and FreeBSD 9

@Kodeus webfacing? I'd rather use AS400 directly than that.

@hexc try writing a readable API for the AS400... that will haunt my nightmares till I die.

@Kodeus AS400? Well guess what I am using day to day

A 20-year-old sun still running applications in production to this day. We are working hard to finally scrap it...
