This parallel port can be used to print from the computer. Some software has printing capabilities built in (such as the text editor VEDIT Plus), but by pressing Ctrl+P in CP/M any text sent to the display will be simultaneously sent to the printer.
I also needed to mount the LCD inside the case. I bought a plastic strip to try to make a nice frame for it, but couldn't cut it accurately enough by hand so have had to make do with merely sticking the LCD behind a rectangular hole cut in the aluminium. It's not the neatest arrangement and doesn't protect the LCD from scratches but is better than nothing.
To demonstrate the computer's hardware and software, I recorded a video:

Watch video on YouTube
I'm not desperately happy with the way it came out; I really need to find a better microphone and the angle of the sun and variable weather when I made the video threw the white balance off. On the plus side, I did find out how to capture crisp black and white video with my TV capture card; I connected the composite video output from the computer to the luma pins on the S-video input on the capture card, then dropped the saturation to zero in VirtualDub. For some reason this produces great quality video, in comparison to the composite input which produces a fuzzy mess ? there shouldn't really be any difference with a black and white signal (regular television sets don't have any problems).
I like the way you used three different kinds of microprocessor / controller in it :)
