What I've never understood about the A2091 SCSI card, is: if you are using external devices via the DB29 connector AND internal SCSI devices, should you REMOVE the terminator resistors from the card itself (blue resistor pack near the SCSI connector)?  The card is in the CENTER of the SCSI chain in this setup:

EXTERNAL DEVICES <----> A2901 <----> Internal Devices

The resistor packs would have to be de-soldered and that would be a real pain.

I have heard conflicting information regarding the above question.

I have used the above SCSI chain for a long time (with the resistors in place).  It's mostly reliable, but once in a blue moon I get SCSI Checksum errors on my external drives (which go away if I reboot).

Well, okay.  I might remove the SCSI resistor packs on the A2091.  But I need to know if I have the right ones identified.  In this picture:

is RN1, RN2 and RN3 *all* SCSI terminator packs?
