Needed: DR11-B equivalent for SGI 4D series

We have a Celco CFR-8000, currently connected to an old VAX using
the DEC DR11-W (new version of the DR11-B) DMA parallel interface.
We'd like to connect it to our SGI compute server (basically a 4D
machine with no graphics). Thus, we need something that goes into
the VMEbus and provides a 16-bit DMA parallel port. It needs to
provide DMA writes only; no read DMA is necessary.
Something that emulates the DR11-B handshake signals would be ideal,
since we could just plug the Celco into it. Something that provides
a 16-bit DMA parallel path with different handshaking would require
us to build some "glue" logic, but that is still workable.
Something with a working driver available would be ideal, but I'm
prepared to write one if necessary.
Does anyone have experience with such a beast?
