Moslo is probably the best of the CPU decelerators. Its freeware for the basic version, but if you need speeds lower than 1% you need the deluxe version. And with a modern machine you may need speeds way lower than 1%.

Also, when you go looking for those drivers, you will almost certainly not have them installed already. You will have to get the soundcard one from the original manufacturer which is usualy not too tricky. The mouse may be harder since M$ stopped distributing their official DOS driver some time ago. I dont have a live link to it right now, but I'll dig it out when I get home. Google should be able to turn one up easily enough though.
