If it has a hard drive, it was probably not used as a Tempest machine. The
TPC I have contains only two floppy drives, and my understanding is that a
tempest machine must have media that can be removed and cannot have fixed
media. Did you get the tempest keyboard and monitor with it? I got mine
about a year ago, and was the first one I had seen. As seems usual though,
no docs came with it. Congratulations on the neat find!
