Anyone know what this:

  http://www.ebay.com/itm/251526917058

is? It has five chips, not six, so it's not the KEF11-BB CIS option. I've
tried Web searches on "57-27889-01", but not turned up anything useful.

All chips on the carrier have the text DC327C-3x (where x is 1.2.3.4.5).
That lead me to "V-11 VAX chip RAM/ROM patchable control store".
And ... KA820-AA.
See http://www.cpu-galaxy.at/Boards/Boards_CPU/Boards_CPU.htm
in the mid of that page.  Nice page, hadn't seen that one before.
Cool looking chip!
