Sun 501-4882 CPU/memory board for Ultra Enterprise systems. (Yes, that name does seem a little silly, but it's what they're called! I'm not making this up. This thing also used the "Gigaplane" interconnect. Sun's titanic hubris is a lesson for us all.) Fits the E4000, E4500, E5000/5500, and E6000/6500.)
Board is fully equipped:
* Board itself, p/n 501-4882, option X2602A* Dual 400 MHz 8MB cache CPUs (p/n 501-5762, option X2580A)* 4 GB Sun original buffered EDO memory, 16x 256MB (p/n 501-5658, option X7026A)
Board is in good physical condition, except that the purple extraction levers are broken, as shown. The board is removable without them, but it's less convenient.
Worked when last used, but I haven't plugged it in in years, and I no longer have any compatible systems to use it with. My recollection is that I left it uninstalled because I had others with fully working extraction arms, and even if they're not important, I like to have the cosmetics in order, if possible.
