The port will be used to control servos. I have used the standard 8 bit parallel port to control eight servos but I now want to control over fifty and so need 50+ output lines I can raise and lower.

Using the parallel port is no longer popular these days, and USB has pretty much taken over for multiple devices and daisy-chaining.  I haven't heard of 64-bit parallel hardware, but perhaps a hobby kit using a PIC? http://electronickits.com/kit/complete/motor/ck1403.htm

Once upon a time PC BIOS's had provisions for recognizing 3 parallel ports at 3 different I/O addresses. This requires that add-on cards are used as most PC's only have one port on-board. Such an array would give 24 data lines to use for servo., assuming your software can use the ports and that you have a suitable PC...

One other possibility is to use the other pins  in the port/connector (not only the data register), but I think you may have a hard time getting 50 control lines nevertheless. Take a look at www.lvr.com/parport.htm .

Next possibility is to use some kind of digital output card. These are often quite expensive, but I think you may look into it if you are serious about this project.
