Systems like that don't even have to be particularly old. I used to work on a system that started out as an Access database, and rather than doing things properly, the developers basically just translated everything into SQL statements and used ASP and COM+ on top of it. It was a load of crap, but it still ran about 10x faster than what customers were used to, so they weren't complaining. Last I knew they were still running the same basic setup, and it's been 5 years since I worked there.
