Found a discarded piece of Plexiglas that almost fits perfectly on the top, and added a front panel cover. The cover had two broken-off pegs in the holes so I used a drill press to auger them out. I am still missing the piece that fits behind the front panel. Click image for larger picture.
UPDATE: ...I see I never posted anything in this thread to mention the fact that I was able to load BASIC via papertape. Although I ripped a tape and needed to patch it, there were no issues I was able to load without problems. For the past few months I have been able to fire up the computer, attach to my Teletype and fire up BASIC from 000 000.
