Share your knowledge on these two classic MPCs

There is at least one jumper set to set the SCSI ID's of the reader slots...

The newer PCD's will have a jumper for termination. For 99% of MPC owners the termination should be ON. On some PCD's to enable the termination requires that the jumper be removed. This is reverse of your typical devices. Most PCD's with this jumper will have this configuration stampled on the PCD itself. The older PCD's do not use jumpers, but use two inline resister banks. If you see a series of holes on the underside of the reader near the 50-pin IDC connector, then you need the resistor block for termination.If they are filled in with something then termination is installed and set.


I'm assuming that my drive uses two inline resistors, and that they are in fact filled in.

In the upper corner of this pic it says TKK-5:

Could this be the "stamped on" congifuration ???

Or does none of that matter, and can i just mount it? :D

It is not too hard to blow the SCSI termination power fuse that is inside the MPC.


I really don't want that to happen :D

The way I'm reading and seeing the pictures... The card reader you have is not terminated.
The second picture you have on here doesn't have anything to do with the termination.
You'll need the 2 inline resistor banks to terminate this. The resistors look a reddish/orange color, about an inch long and should have 12 to 15 pins (i'm guessing how many. It's been awhile since I've seen one) sticking out of it to be able to insert into the series of holes (First picture) near the 50 pin SCSI connector. Thats' why it's labled R22 (inline resistor bank 22) and R23(inline resistor bank 23)... This is where the inline resistors are to be placed for termination.
Hope this helps.


one...

Good Look!
