Unibus Framebuffer information needed (DDS)

By luck I stumbled across what may or may not be a complete hex-width Unibus framebuffer board set made by Dynamic Digital Displays. Now that would be cool in the PDP-11/84. :) I can identify three of the boards but not all of them: -FB1000FBL001 Serial 55 Rev. 2 (looks to be the main memory as well as the D/A logic to output to RGB) -1000VB-001 Serial 35 (calls itself the "Voxel Buffer") -1000CTD001 Serial 47 (calls itself the "CTU Board") These boards can be seen at the following link: http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… Then there were two other boards that the seller had as well. They may be related to the previous three and they also might not be. -1000HIL001 Serial 45 (board calls itself "HI") - http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… -1000DTD001 Serial 54 (calls itself "DOTS") - http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… Unlike the first three boards, these ones have "Dynamic Digital Displays" on them, however the model numbers are similar on their structure. The unfortunate part is that these boards have connectors on them ("HI" board has three 40-pin ribbon cable headers, "DOTS" has two 50-pin ribbon cable headers) so either I'm missing more boards that that talked through their own bus and not the Unibus, these connectors are for options, or there is additional hardware/cards I am missing. I have no way to read the two TMS27C512 EPROM chips and Google has pretty much nothing about these boards that I can locate and their hand written serial numbers mean these are something special. Might anyone have further information on this?
