Sharp PC-7000

I just today acquired a Sharp PC-7000 "lunchbox" style luggable, I thought it was a boombox until I opened it up. I know that it is an MS-DOS (XT or AT class?) machine, but now I need software for it. Can someone direct me to a good software archive for this machine? Also, what is the purpose of the metal-covered (screwed shut) connector on the underside of the machine? Is it for an external hard drive? ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.
