It's not abandonware, but does anyone own Jasik Debugger and want to try it out in an emulated system?
It includes a software mmu of sort (that's my understanding) and could maybe be used in some way to run programs that require MMU.
The ancient program costs 225 bucks, but the website hasn't been updated in eight years. Anyone here outgoing enough to see if the author has any thoughts about releasing the program into the wild?
