Quantex 650 / 2200 QIC tapedrive

Hi, I'm thinking of getting my Zilog System 8000 maybe one day back to life... this includes multiple tasks. - get a working harddrive - get a working tapedrive - get access to tapes containing the OS and the diagnostics Right now I'm thinking of the tapedrive part. The original drive is a DEI CMTD-3400 http://www.bitsavers.org/pdf/dei/CMTD-3400S2_4tk6400bpi_1979.pdf I have one but it is broken in multiple ways - the previous owner I got the drive from replaced it in the 80s as it was failing (no further details available) - the motor does not run smootly - it does not start on its own when powered up and the UPM is changing. I was not able to open it. - the rubber wheel went to fluid (usual problem...) I now got a so called "Quantex 2200" which is a 19" case with two Quantex 650 drives which should be able to handle the same tape format as the DEI drive. All I was able to find about this drive was: http://www.bitsavers.org/pdf/quantex/TM1001_650_Jul81.pdf Does anyone have any experience with this drive? I wonder if I could make it "connection compatible" somehow with the DEI drive. The manual itself talks about a controller board which is the only whay the drives can be bus driven - it looks like the drives in this 2200 case do not have this optional controller board. Maybe they do not have it because the big plate in top of the case is a controller board for both drives... Who knows - I did not find anything usefull about this 2200 case nor how it is supposed to be connected to what (pinouts). The rubber wheels are as well went fluid. I could also need some ideas how to get a QIC drive capable of reading and writing DC300XL QIC cartridges hooked up to a PC with BSD or Linux running as in some point in the future. I must be able to copy the system tapes (reading + writing) with a PC. Pics of this 2200 case: http://pics.pofo.de/gallery3/index.php/S8000/Quantex-2200 Greetings, Oliver
