There is an early prototype of that fixture. It allows the analog scope to function without any other digital cards. The prototype is a subset of 067-0912-00. It is pictured on Kurt R¡¯s tekwiki page for the 067-0912-00 fixture. It allows selecting Vert and Horiz display modes. It reduces the 7854 to a 7804N. Contact Dennis Tillman. I gave him a board a couple of years ago. He made an offer to this group to have a few made but nobody was interested at that time.
