Welcome to the murky waters of abandonware, where you can’t buy the product from a vendor anymore and downloading it for free is still considered illegal due to copyright.
But obtaining the product is only half your problem, since running pre-'95 titles on today’s operating systems is pretty much impossible without some sort of patch/emulator.
I wish you luck. If there is a demand for it, maybe Microsoft will go a bit further than just a flimsy in-game emulator within MFS.
