TSR? Looking at an old mouse binding in Ada I see in the comments: -- uses int33 functions ... -- In 1987 this interface was standard and supported by all PC mice. which suggests the code dates from 1987. I also found an old (Ada) .com program, 36K in size, which displays atomic orbitals with the perspective changing as you move the mouse. I doubt the mouse takes up "35kb" of that. (To my surprise, it still runs under W2k!)
