Hello All, Is there someone on the list who can supply me with a photocopy of the wiring diagram of the cable used between the reader and the interface? I need to fabricate the cable. If you have some punched cards as well to spare that would be great!

PDP-11 with real ADV11-C board still unhappy

Anyway, hopefully it will stay that way. Well done! You've fixed it ;-) Seriously, it's often stuff like that which catches us out. On the positive side, you've learned a few things, and had a bit of fun (depending on your definition of fun). -- Pete Peter Turnbull Network Manager University of York

Probably, but I'm not sure what :-) You could try halting it and see if i always halts in the same place(s). If so, it would be worth looking to see if you can figure out what instructions it executing at that point. It might be a WAIT or a polling loop. Also look at the vectors in low memory (from locations 0 to about 20), and the vectors for the devices you have in the system. They should point to somewhere in the program. > I did try doing a "770400/" and it returned 000000, with the > module out it gives a ?, so that seems good. 770402, the data buffer > returns 007777. Sounds like you have it set up correctly, at least as far as addressing is concerned. > Does anyone know what to try next?

The order of the modules shouldn't matter, though it's best to have CPU-memory-serial followed by whatever device needs highest priority response. I expect the DSD RX02 controller works just like a DEC one as far as addresses and interrupts are concerned, so that's unlikely to matter. The BDV11 is another story, though. It includes a line-time clock, and your system may need that. IIRC, it's controlled by a combination of a switch on the BDV11, a bit in a register on the BDV11, and the LTC switch on the front panel. All of those have to be enabled, and the BDV11 must be present, for the clock to run. I have seen systems that boot but then hang if the software needs a clock but it's not present or is disabled. -- Pete Peter Turnbull Network Manager University of York

Security bits and screws

Ah, that's the rub: I'd been expecting to see a security bit shaped like the triangular hole, but you're saying the tri-wing (with three vanes from the center) is the proper bit for those screws... - John

RT 6150 Docs (and mouse??)

There is an RT newsgroup that has ontopic postings every once in a while so you can ask there for questions. Did you get the desktop or tower form factor? Desktop can only have 1 drive AFAIK. 16meg is the max mem i believe. Mine has a MDA so I can run text only but am getting a Megapel for it soon. Not rare machines, but I've never seen any besides the one I have. I'd hate to pay shipping for it though, extremely heavy! -- Antique Computer Virtual Museum www.nothingtodo.org

RT 6150 Docs (and mouse??)

by doc＠mdrconsult.com

Hi. Does anyone have pointers for detailed documentation? A mouse, maybe? And which operating system - AIX v2.2, BSD4.3, or AOS - do I want to run? I'm leaning toward AIX, mostly because I work with "modern" AIX, but I'm plenty willing to take suggestions. For that matter, what *is* AOS, anyway? I just found out that I got in first claim for a functional RT 6150. I can't pick it up till tomoroww afternoon, though.... The guy who's giving it away says he "has no boot disk, but it starts up just fine."!? He also thinks it has 3 drives and is maxed out on memory. It comes with a display and keyboard, but no docs and no mouse. I've been googling, and there are a lot of mentions of it, but no real information. This is kind of a special score. I never used computers at all till late '95, and started building my own in '96. That spring, I went to pick up a video card from a guy who had an RT 6151, and it was the first time I really grasped that the world wasn't all Mac & PC. I've wanted one ever since. I guess all things come to those who lurk. Doc

Every VW (and Audi & MB, etc) of that vintage that I've seen used CIS, which was a purely mechanical system. I have seen a 1969 Audi Super 90 (wagon) that had an aftermarket Capacitative Discharge Ignition (CDI) System... by 1974, Audis had those as stock, while CIS was still 1 year off... My 1986 Audi 5000 CS Turbo Quattro uses a Motorola 6802-based controller... very simple to upgrade, too.... ;-) -dq

looking for DEC VR160 monitor

Hey folks. I'd like to find a DEC VR160 monitor (19" mono) at some point. Does anyone have one that they want to get rid of? -Dave -- Dave McGuire St. Petersburg, FL "Less talk. More synthohol." --Lt. Worf
