board found

I looked in a box here that I hadn't looked into in a while, and found this board... It's _not_ ISA, PCI, or any of those formats. Says on the top "Panther EDAC Memory Board". There's also what appears to be an NCR copyright on it, 1993. There are a half dozen big chips across the bottom where the edge connectors are, 5 of them marked VLSI and one NCR with a 1990 copyright date on it, and eight SIMM (?) sockets, but these are not your standard ones -- if I take a 72-pin SIMM and line it up with the notch with one of the occupied sockets on the board, I have 3-4 pins left over (on the part on the board) at each end. Four of the sockets are occupied. The two in the middle that aren't are labeled "Bank-1/3 Byte-2" and "Bank-1/3 Byte-1", I can't see the markings for the other ones and don't want to pop these SIMMs out at the moment. Near the center of the board are four other sockets, with a chip in one of them, looks almost like a SIP but the pins are in two rows, real close together, coming out of the same side of the package (what do you call this?) and the part in the one socket that's occupied is marked "Toshiba" and "TC5117400Z-60". There are also 3 barcoded stickers one of which bears the date "Oct 31 1994" in the middle of two barcodes. This *may* belong with that NCR tower that went out of here a while back, I don't know for sure. Anybody know what it is? Anybody maybe have a use for it? -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.
