Paul; The A2091 (and probably the A version too) is not correctly designed. The terminators on the A2091 are not removable. Thus you SHOULD use only the internal or the external bus (though you can use a drive on the card itself (without terminators) and still use the external bus (the cable to the internal drive will be less than the stub limit for a drive mounted on the card). Now having said that, I personally have not seen an A2091 that will not work with three sets of terminators present (one set on each of the ends of the internal and external buses and the one set on the card). I also know of people that have cut the leads on the internal terminators and that too has worked. Something else that works nicely is to install a Maxtor MXT-540 drive anywhere on the bus with the terminators "on." The active SCSI-II terminated MXT-540 settles an improperly terminated bus even when the MXT-540 "is not supposed to be terminated" because of it's position on the bus. This was first (as far as I know) done by a Maxtor employee that is also an Amiga owner. A bus analyzer indicated that putting the MXT-540 at ANY location on the bus improved the bus termination. Subsequently other Amiga users trying the same "trick" obtained the same appearent results. Hopefully, someone will find their copy of the A2091 manual (I have not been able to locate mine) and tell you what memory chips to use. -bill
