Another identification needed...

I have a few more boards which need identification. Again, the scans can be found at ftp://ftp.std.com/ftp/pub/mbg/scans/computrol_30-0096_7.jpg it is a two-board set. There is an over-the-top connecting cable and a thin cable with a bnc connector on the end. One board is labelled 'Memory Map Megalink 1' and 'dma bus' and the other is labelled 'Memory Map Megalink 2' and 'datacom'. They're qbus boards, but with no switches for setting addresses and/or vectors. Can anyone identify the pair of boards? Thanks in advance...
