[net.micro.68k] Omnibyte CPU Card Users attention

jbn@wdl1.UUCP (01/30/85)

      Users of Omnibyte VMEbus CPU cardss of serial 3090 and down:

      Check your board for a Motorola 68432 chip at position U35.  If one
is present, your CPU card will not function properly if there is more than one
bus master.  The Motorola bus arbiter chip must be replaced with a two-chip
set on a daughter board to make the card work in a  multiple bus master
configuration.  Contact Omnibyte and get the Field Change Order 5 kit.
(part number OB68KVME1FCO5, parts kit VME1FCO5K.)
      This fix cured a serious intermittent problem for us encountered with
three bus masters in one VME cage.
