It is not only that, actually. A bidir. port with possibly exposed interrupt and other bus lines would allow hardware types to connect a variety of home-built devices and write drivers for them. An example: there are very cheap (US$10) flash AD converter which can be used to sample video signals. They work reasonably with a sample rate of 1MB/s or more. I have done this on a spare IDE card, but the parallel port connector is way easier to use.
