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

by maxeskin＠hotmail.com

Who exactly decided that there was a frequency change? It seems strange that they could have known if there are no monitors to check and this is not a central problem. Of course, if this was a resonant transformer and the guy shorted it, or he hooked the transformer to a portable generator that the construction company was using, or he temporarily powered it with a solenoid using a jackhammer for a slug... >> Who knows hertz and 60 volts.

Spring CP/M-UG N.W. Swap Meet this Saturday

by jimw＠agora.rdrop.com

For those in the N.W. Oregon / S.W. Washington area (or those inclined to drive a bit) B^} The 'n'th Annual Spring edition of the CP/M-UG Swap Meet will occur on Saturday June 6th, on Rose Festival Parade day just as always. It will be held in the lower level of the Senior Citizens Center on Omera, just south of the Tigard (Oregon) City Hall on Hall Blvd. (not too hard to reach from I-5 or Hwy-217) As always, it's Free, Easy, and Non-Fattening! (except perhaps to your wallet or garage, depening on your approach!) Bring your Junk, your Treasures, and your Wallet! The only rule is... Leave Nothing Behind! (NO garbage service!) Address: 8815 S.W. Omera (Just south of Fanno Creek on Hall Blvd.) Tigard, OR. Hours: 0800 to 1500 or whenever the good stuff runs out! (8am to 3pm for the layfolk) Fees: No charge! (we pass the hat for contributions) NOTE: Tailgating is encouraged! Some of the best deals are made in the parking lot! (before, during, and after!) See you there! --- For additional details, (directions, etc.) call Gary @ Oregon Electronics (503) 293-5293 or drop me a e-mail. -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

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.

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.
