RL-02 Question

by healyzh＠ix.netcom.com

In the pile of stuff I got yesterday was an RL-02 and a Q-Bus controller for it. I've placed the Q-Bus controller in one of my SMS-1000's (PDP-11/73), and am trying to get the drive to spin up. Looking through my archives of the mailing list, it looks like the drive itself is fine. I think my problem is on the PDP end. The motor spins for about 15 seconds, I hear the click, but the fault light stays on. I've reversed the way I've got the cable plugged into the board, but still know luck. I suspect my problem is that the SMS-1000 doesn't support RL-02's. The Boot ROM's seem to be built into the beast, and I suspect it only supports Hard Drives (DU), TK50's and floppies. I guess my next project is to try and attach a TK-50 to the machine, as I got a small stack of TK50's with the stuff yesterday, and it looks like they've got TSX-11-something on them. Do PDP-11's have the VAX equivalent of Standalone Backup? Zane | Zane H.

What is it called when the 60hz line power becomes something else?

And on some IBM mainframes, I believe. A friend of mine obtained a 360, and was most upset when the previous owner decided to keep the 50Hz-to-400Hz converters. -- Pete Peter Turnbull Dept. of Computer Science University of York

My RSX11M 3.2 and 4.1 manage fine. AFAIR, it's supported -- it's certainly in the manual somewhere. The driver understands that it has to be careful about using the bottom 124K words for disk access. -- Pete Peter Turnbull Dept. of Computer Science University of York

Yes, but are they still valid if the owner is out of business? I know the HK manuals are WIDELY copied and the copies sold. So are Tektronix, HP and a lot of others, and they're still in business!

RL-02 proves me an Idiot!

by healyzh＠ix.netcom.com

Well, I've got my RL-02 on the /73 working. The cable on the back had the locking key in the unlocked position. Arrrgggghhhhh, it took me a day to figure that one out! Lesson learned, visual inspections just don't cut it! Of course I don't seem to have Boot ROM's in the SMS-1000 that support the RL-02. I tell it to boot dl0: and it tells me it's an illegal device. Yet the RSX11M boot tape tells me that's the device name. I still haven't been able to figure out what they guy I got this stuff off of could have been using to boot it. Zane | Zane H.

It will work in a Q22 backplane providing you remove two links, which otherwise cause the RLV11 to use BC1/BD1 for "other than BDAL18/19". It has to be a straight backplane, with CD-interconnect, of course. Even then, it only does 18-bit DMA, so whether it's useful depends on the O/S -- RSX11 and Unix manage fine, but I don't know about RT-11. -- Pete Peter Turnbull Dept. of Computer Science University of York
