If you can find Art Snapper or Jeff Ingliss (Englis? Engliss? Inglis?) they
might have one they are willing to part with. I used an 8 for much of my
graduate career. When the thing crashed, you'd have to toggle a bunch of hex
code in order to load the OS from paper tape. We thought we were fortunate
when you could boot the thing on 8 ½ in floppies!
