>After more than a year on a desk, I mounted the 6125 tape drive in the top of the rack with its power supply on the right side next to it. I went to mount my 6125 today, but alas I may have to get creative. My 6125 was in a "desktop" stand, and when I remove the power supply and also look at the DG Installation docs - it appears that they used a different sheet metal backing to mount the 6125 in a rack (on the side, as you say) rather than on the desktop unit. I was sooo hoping to just remove and mount. Well, either they used different metal or my vertical posts are spaced different than expected. I don't think it's the latter, because all the measurements matched with the installation guide for the cpu and the 6030 disk unit. Hummmm.. looking at pictures... it's the former. The sheet metal the PS is mounted on is definitely shorter (left to right) on mine than what is pictured. I guess I now have a use for the metal brake that I just bought yesterday that is still in my car ;) >Indeed! I feel like being spoiled by DEC with connectors for everything. Anything I would say to that would probably start a flame-war between DEC and DG enthusiasts, so I'll just leave that one alone ;) >I have the controller board for the 6125, but I do not have the cable from the backplane to the paddle board. I *think* I do have the cable from the paddle board to the pin header on the 6125 board (the horizontally mounted one). As Bruce pointed out to me, there are actually only a few different backplane wirings. Since it hasn't been rackmounted yet, I haven't gone searching all the DG racks to see if I have any of the internal or external or device cables for the 6125. We'll see. I suspect I will have to make all my own cables; all my DG gear came from two collectors in separate acquisitions - with one exception. This 6125 I bought off a shelf at the local electronics haunt years ago, and it had no cables. >My 6125 did power up correctly, but when I mount a tape and press BOT, it spools some tape and then stops. When I press BOT again, it spools again some tape. Did that a few times ... had to manually rewind the tape as REWIND did not work. Could be a missing BOT on the tape, or issues ... If there's no BOT tape on the tape, yeah. If there is, I'd look first at testing the BOT/EOT sensor. I think there's a procedure for that in the manual. ISTR that when it hits the BOT tape, it actually backs up a little so it can get a "running jump". >Keep posting! I am a "newbie" on DG stuff with a long road ahead. Ditto here, new to DG gear as well. Bruce has been a great help, but pouring over docs for hours has been invaluable. Best, J
