Unibus Backplanes

Type	Slots	Description
DD11-A	4	The end slots are Unibus in rows A and B, one of the middle slots, row A is for the power connection. Rows C to F are SPC.
DD11-B	4	The end slots are Unibus in rows A and B, the middle slots, rows A and B are for DF11. Rows C to F are SPC. Power connection is via a harness and faston tabs.
DD11-CF	4	The end slots are Unibus in rows A and B, the middle slots, rows A and B are MUD (?). Rows C to F are SPC. Power connection is via a soldered harness for a BA11-F mounting box.
DD11-CK	4	The end slots are Unibus in rows A and B, the middle slots, rows A and B are MUD (?). Rows C to F are SPC. Power connection is via a soldered harness for a BA11-K mounting box.
DD11-DF	9	The end slots are Unibus in rows A and B, the middle slots, rows A and B are MUD (?). Rows C to F are SPC. Power connection is via a soldered harness for a BA11-F mounting box.
DD11-DK	9	The end slots are Unibus in rows A and B, the middle slots, rows A and B are MUD (?). Rows C to F are SPC. Power connection is via a soldered harness for a BA11-K mounting box.
