Brad, Sounds like you're on the path to ultimate success - keep at it, and you'll get to the heart of it. There's no better guarantee for success than simply refusing (aka failing) to give up at any time. Take needed breaks, review docs, listen to suggestions - but never, ever quit until it's

Unibus controller for MFM disks

I don't know that Digital ever had a Unibus disk controller for ST412 interface disks, but were there any third party controllers? I'm in need of disk controllers for PDP-11/40 and think that might be an option given the availability of reliable MFM disk emulators. -chuck

Re: ASR 33 buzzing

I see you didn't bother to check the clutches. You'd have found that the clutch that reset the keyboard could be released. The buzzing may also be related to your fuse blowing the supply that feeds the receiving coil may have a shorted diode or capacitor. That would both explain the fuse and

Got a little further. The keyboard was definitely jammed. I pulled the carriage over to the right and noted there's a bar on the left side that a piece of metal attached to the carriage belt hits, I assume triggering something. Doesn't work.. the bar is stuck. At any rate, I put the metal

RE: ASR 33 buzzing

Okay so, a bit more playing around. The buzzing stops if I rotate the motor. And then after rotating the motor if I power on and off, it just makes a single click. Every so many turns though it starts buzzing again. So maybe we need to get back to the motor and why it's not doing anything?

Re: ASR 33 buzzing

It would actually be coming from the motor not the reader. The motor for the papertape reader is either in the pedestal (if your ASR is on one) or somewhere in the UCC-6 (the power supply). You have to follow the cable that comes from the reader along the rim of the chassis. B On Fri, Oct 14,

Check that all the clutches lock up. You can do this by hand. If they drag it can stall the motor. Rotate and push on the tab on each. You have to hold the one from the input coil as the last one. The tension from rotating should hold them all. Always start it in local to reduce the load. If
