The first machine I opened (3100/76 SPX) does have all the SCSI stuff
onboard.

  The second box (3100/38 with graphics and flopp) does have a SCSI
daugher board, but it's quite different to

http://home.iae.nl/users/pb0aia/vax/vs3khw.html . I made a photo of my
board: http://lug-owl.de/~jbglaw/VAXstation_3100m38_scsi_board.jpeg

  There are, I think, two more MicroVAX 3100 systems down there, which
I didn't yet dismantle. Though the could have a matching board... Will
check these tomorrow.
