The native DOS version of The Laffer Utilities would still probably work fine in DOSBox, but the only version of the program I know of that's been archived was the Windows port. If the DOS version is out there, I know not where.
Not that you're missing out on much, really. It's just a badly-dated* "infotainment" product from the early '90s that was more or less a Print Shop clone mixed with simple databases for dirty jokes, places to go for lunch, office pools, and stuff like that. I'd like to have it included for the sake of completeness, but it's not worth losing sleep over IMO.
* - With Larry, is there any other kind of date?
