Subject: are the 3 terminating resistors identical?

I removed the 3 internal terminating resistors from an Ehman 40 recently
because I was attempting to put the drive in the middle of a SCSI chain.
I was able to get this to work, but when I put the terminating resistors
back in I was unable to use the drive on the MacPlus that its usually used
with, but the drive worked fine on the IIsi. I looked at another Ehman
drive that we have in the lab and noticed that one of the 3 resistors
was different in having some numbers on the top. When I rearranged the
resistors in the problem drive so that the "different" resistor was in
the same position as it is on the other drive the problem disappeared.
Are all 3 of the resistors the same or is one really different? What's
the significance of the order?  Thanks for your help.
