99% of Compaq stuff is Compaq stuff. It may be manufactured by someone else but the firmware will list it as a Compaq peripheral. Got to
www.driverguide.com and put a search in for "compaq presario 1640 video driver" and see what you get. If it's less than 1.38 MB's in size or you have a splitting
utility to send it to multiple floppy disks then, yes, you can take it to you other machine.
