Where can I get terminating resistors for old SCSI drives?

Post by ral-clan »

Hi, I'm putting a Quantum Maverick 540MB hard drive in an Amiga 3000.
This type of drive uses resistor packs to enable on-board termination.

Unfortunately, the resistor packs are missing. More unfortunately, they seem to be not the more common kind, which uses three 8-pin resistor packs. Instead, this drive has space for two long 10-pin resistor packs.

Here is a short page/image on the drive:

Does anyone know what kind of resistor packs these are and where I could get some today?

Would I just be better off getting one of these on Ebay?

It's an internal in-line active terminator with pass-through. You plug it into the device you want to terminate, and them plug the ribbon cable into it.

SCSI active terminator

I have a male SCSI 50 pin Male Active terminator.

I can send you the cable as well, if you need it.

Send me a PM if you are interested.

Thanks, but I really need the pass-through option. I think I'll just buy that one on Ebay.

You can terminate on the device, or terminate after that device on the SCSI cable if you can't find a terminator pack that fits the device. I've got a couple of drives that I don't have terminators for, so I use a cable with an additional connector and plug in a terminator after the drive. I've also done the opposite for a SCSI host adapter for which I couldn't find the nonstandard one-off terminator block--connected the board to the second plug on the cable, with a terminator on the first plug.

Resistor packs are standard components used for all sots of purposes, not just termination of signals.

You can get billions of different types of resistor SIPs on Digikey.com (digikey.ca).

Also, on-cable SCSI terminators are very easy to find on eBay. The one you offered a link to on eBay seems outrageously expensive as I have seen terminators going for less than 4$.
