Hmmm...interesting. No, the terminator is not installed in slot RN1 on either of the 2 drives I own. The system I used it on it only designed for a single drive so that's all it can handle and I've had this drive since the computer was new so I can guarantee this is how it came installed.brightcaster wrote: ↑Sun Nov 21, 2021 9:08 pm This is in deed a very poor signal quality! Is the terminator plugged in? (Look at page 20/21 of the manual for function and position on the PCB.) Was it the only drive in the original machine you tested it with or was there a second drive connected?
Otherwise I could only think of a EMC problem at the moment. Do you feed the drive with a separate power supply which is not connected to anything else but mains and the drive itself? Does the power supply have a ground connection, which leads to a "ground loop" to your PC?
Does that mean it needs to be installed to use it with the Kryoflux and apparently not installed to use it on the actual system? I wouldn't even have any clue where to find one for it unless it's a common thing on Digikey etc. It appears to be a 14 pin slot (not 16 weird).
Or possibly connect it to the second drive connector on the Kryoflux and put a terminated drive (e.g. the Teac) on the end of the connector?
