I really enjoy toying with retro software. Not that there is anything wrong with retro HARDWARE, of course, far from it. But for all the imperfection and impurity of emulation, it makes it very easy to at least approximate the software experience in question. I have mostly emulated games, but I have wanted to try something dry and practical. As I have worked a bit with databases, it was probably only a matter of time before I located a copy of dBASE for DOS. It certainly makes for a fascinating glimpse at what database work looked like before SQL became the big thing. I am using it to keep track of my library loans, which is a nice and simple use case. I am normally a Linux guy, but I do like to dabble with FreeBSD on a VM. It will be a while until I have the courage to take off the training wheels, but it's good for practice if nothing else.
