I tried this. It didn't work, at all. I had a few sizes of nitrile O-rings I use for another purpose (micro lathe drive belts) and tried a range, the BS336 as mentioned worked perfectly. It may perhaps work for other brands of tape unit if the hub pinch clamp arrangement is the same diameter but that is for someone else to try. Steve.

Blair http://www.nf6x.net Mark, you probably know … It is best to get a truck with a tail lift. Then you can roll the entire rack into the truck. No hassle with disassembly and making notoes how everything was routed. BTW, the disk drive in the bottom is *heavy*. You could lift it by yourself, but that Is not very clever. Better lift it with two persons. The same goed for the Kennedy tape drive – heavy! And the 11/34, in a 10.5” box will be heavy at the rear side where the transformer and power supplies are. So, disassembly will give you 3 heavy items best lifted by 2 guys. Leaving it in the rack and pay a bit more for a truck with tail lift, is a wise decision for your back! Regarding the rubber rings on the hubs of the tape drive, I remember that somebody once told that when the rubber tension is weak (because the ring diameter got a bit bigger, you can get the ring back to its original shape by putting it in warm water. Worth a try if needed … Henk, PA8PDP

BTW If the old rubber rings one the hubs are too expanded and won't allow a tape reel to slide on, just replace with a # BS336 O-ring from a bearings/seals/gasket shop. These are cheap, readily available and takes seconds to install for a perfect fit. Steve.

Re: 9-Track Magtape Drive ID
Cool. So that means that this 11/34A has more backplane slots than the base model? The programmer panel is also appealing. I presume that the Kennedy 9000 doesn’t have a Pertec interface, then? It remains to be seen whether I ever start my 11/44 restoration vs. moving it along to another collector and using some of the boards I accumulated for it in the 11/34A. I’m on the fence about that. -- Mark J. Blair http://www.nf6x.net

Re: 9-Track Magtape Drive ID
Looks like a Kennedy 9000 series, with the sliding panel and all. On Sat, Jun 1, 2019 at 12:53 PM Mark J.

45ips tension arm 800/1600 looking at the 'density' slide switch make shure you get the cables and controller board if you don't take the whole system On 6/1/19 10:56 AM, Al Kossow via cctalk wrote: > kennedy 9000 > > On 6/1/19 10:53 AM, Mark J.

Re: 9-Track Magtape Drive ID
I don't know for sure, but it looks a heck of a lot like the drive I loaded for backups on a 11/34a that the company I worked summers for had. 1983 or 1984 was the time frame.
