The pin out for DRV11-WA produced by DEC is shown in the table below.
The User's Guide for the General Purpose DMA Interface, DRV11 WA, was produced in 1986.
as Book Number; EK-DRVWA-UG-002.

However this pin-out was extracted from a document I wrote in 1992.
Part of the specification for a custom card design that interfaced to a DRV-11 card.
Either way, this interface is obsolete, being produce for the uVAX series of computers.
That is, the entire line of VAX and uVAX computers are out dated and obsolete.

Note that some of the pin labels are not used; for example, G, I, O, Q, GG and so on.
The outputs from the DRV11 card are standard TTL single-ended Totem-Pole drivers.
The design I used included the following ICs for interface:
Two 8-bit 74AS574 were used to drive data into the DRV11 [16-bit wide bus].
True table and data on the similar 74xx374 octal flip flop.
The outputs from the DRV11 were not used in this particular design example [being output to another card].
Both the input and output data width for the DRV11 is a 16-bit wide data bus.

Digital Equipment Corporation [DEC] was purchased by Compaq in 1998.
The DRV-11 card was a board used on the Q-Bus, so it's a sub-bus of Q-bus.

VAX Buses [Digital Equipment Corp.], include DR11W, DRV11, Q-Bus, and Unibus.
VAX interfaces were superseded in the 1990's by the Alpha computer lines, and then discontinued in the early 2000's.
VAX and MicroVax were never used as personal computers.
